the present invention is directed to a novel composition of a porous crystalline material , in both “ as - synthesized ” precursor form and its calcined form ( termed ics - 3 ), and methods for their preparation . whilst having some structural and synthetic similarities to zeolite zsm - 57 , this is a novel material . it possesses a similar x - ray diffraction pattern to that of zeolite zsm - 57 however it also includes reproducible additional peaks indicative of the novel phase . mfs is the structure code of zsm - 57 . zeolite zsm - 57 has interconnected 10 - membered rings ( mr ) and 8 - mr channels , i . e ., intersecting 10 - and 8 - mr channel systems . the synthesis of zsm - 57 uses the same template , diquat - 5 as in the present invention . the raw materials required for the synthesis also have some common features . novelty arises from variation in proportion of templates and aluminum sources and in the novel zeolite structures produced . the novel zeolite ics - 3 is believed to be a relative of zsm - 57 . this could also be seen in that the x - ray patterns of both ics - 3 and zsm - 57 have a number of common lines . “ as synthesized ics - 3 ” which is a layered pre - cursor form of the novel zeolite ics - 3 . the “ as - synthesized ” form includes pores still filled with templates and the active sites are generally inaccessible due to its layered structure . “ calcined ics - 3 ” or ics - 3 proper . this is the form of the zeolite once the as synthesized form has been heat treated . the structure is no longer layered in the same way ; the layering has been destroyed ( the layered structure collapses upon heating ). such a zeolite is particularly of interest as each sheet contains active sites and pores thus the reactivity is very high due to the high accessibility of these sites . the invention relates to the as - synthesized precursor ics - 3 and its calcined form . the general formulae for these are : as - synthesized : ( 0 . 001 - 0 . 5 ) m 2 / n . sio 2 . y al 2 o 3 . ( 0 . 15 - 2 . 0 ) r . z h 2 o where , m is the group i or ii cation , n is the valency , y is the moles of alumina and r is the organic template , z is the moles of water . calcined : ( 0 . 001 - 0 . 5 ) m 2 / n , sio 2 . y al 2 o 3 . z h 2 o . the original sodium cations of the as - synthesized material can be replaced in accordance with techniques well known in the art , at least in part , by ion exchange with other cations . preferred replacing cations include group i , ii , iii , transition metals , noble metals and rare earth metals . the as - synthesized material , ics - 3 is found to be layered based on the x - ray pattern . the presence of peaks at lower angles is characteristic of layered materials . in this case , the peak at 2θ = 4 . 439 ° is distinct and disappears upon calcination . the calcined material does not have this peak , however , there are two other peaks with very low intensities in the range ( 2θ = 4 − 5 °). this is attributed to the collapse of layers upon calcination and fusing of the sheets . the structures are also evident from micrographs of the two forms of the zeolite . fig1 is the transmission electron micrograph ( tem ) of the as - synthesized material , magnification = 50 , 000 . the tem shows the uniform lattice fringes without any patterns due to intergrowths or any other disorder . fig2 is a more magnified tem ( 200 , 000 times ) showing the distinct lattice patterns . fig3 ( a and b ) provides scanning electron micrographs ( sem ) of the as - synthesized layered precursor . these figures show the zeolite has a large crystal form comprised of numerous nanocomposites . there are flat sheets which are probably nanocomposites fused during crystallization . the layered nature might arise from the inter - sheet distances or the inter - particle distances . fig4 ( a and b ) provides sems of the calcined ics - 3 showing that the sheets have fused upon calcination . the layers stack upon each other , having collapsed upon heat treatment . the surface areas of the ics - 3 ( as - synthesized and calcined forms ) were ascertained via brunauer , emmett , and teller ( bet ) analysis and are presented in table 1 . the total surface area is obtained by fitting the nitrogen adsorption isotherm with the bet equation . the measurement is carried out by adsorbing nitrogen at liquid nitrogen temperature . the t - plot method by lippens and deboer yields the external surface area . the difference between the total and the external surface area yields the micropore area . the as - synthesized material does not have any micropores due to the template remaining in the pores and between the layers . however , a little surface is available for the nitrogen adsorption due to broken channels , partially decomposed templates or available pore mouths . thus , the surface area is substantially only the external surface area in the as - synthesized material . upon calcination , the template decomposes completely leading to exposure of the surface . thus , an increase in the surface area is observed . the particle sizes are from 50 - 100 nm composites , fused together . thus , a comparatively very large external surface area is expected , and the layered / thin flakes are shown to possess large external surface area . the preparation of the novel zeolite of the invention is typical with respect to synthesis of other zeolites . the processes involved are the hydrolysis of silicates , addition of templates or the structure directing agents , addition of an aluminium source and / or followed by the addition of a base such as na , li or k hydroxides and water . the ratio of components which can be used in the formation of as - synthesized ics - 3 are as follows : there are two important factors in the preparation which give rise to the novel zeolite of the invention : a ) the use of aluminium nitrate as the aluminium source , and b ) the amount of template added . we found that use of aluminium nitrate gives rise to ics - 3 whereas the use of aluminium sulphate led to a mixture of different materials , which on occasion yielded ics - 3 ( as synthesized ). the identity of the template is important in the preparation of ics - 3 . the template is n , n , n , n ′, n ′, n ′- pentamethylene ( bis tetraethylammonium ) bromide ( diquat - 5 ). the amount of template is crucial . the layered structure is favored with higher amounts of templates ( r / si & gt ; 0 . 08 ). lower amounts ( r / si & lt ; 0 . 07 ) lead to different zeolites namely , zsm - 57 along with or without zsm - 5 , mordenite and quartz . 1 & gt ; r / si & gt ; 0 . 08 leads to the layered material . the preferred amount being r / si = 0 . 1 - 1 . 0 . all types of sources of sodium as would be known in the art , such as , sodium hydroxide , halides , salts , and metal complexes are possible . other potential sources include a combination of hydroxide with or without sodium salts such as , sulfates and halides . the synthesis conditions have to be optimized upon variation in sources . we note that the sodium cation is the preferred cation however the use of other cations such as lithium , potassium or cesium ( eg in the forms of lioh , koh or csoh ) may be selected without departing from the scope of the invention . the ph of the process is important . we wish the ph to be kept in the range between 10 - 13 . 5 . when the sodium source is naoh then a base is not required as the ph is substantially in the required range . however when the sodium source can be fully or partly substituted by another species ( such as nacl or na 2 so 4 for example ), and the ph is altered . in this case , the ph is maintained by the addition of bases such as ammonia or other quaternary ammonium hydroxides , or amines or alkali / alkaline metal hydroxides partly . the identity of the silicon source is important . although a number of silicon sources could be used , as would be known in the art , in the present case , ludox hs - 40 ( aldrich 40 wt . % sio 2 0 . 41 wt . % na 2 o and 59 . 59 wt . % h 2 o ) was by far preferred . hs refers to high sodium content . ludox hs - 40 provides us with the most reproducible results . we have also conducted a few studies with a variation of silicon sources such as with ludox ls - 40 ( aldrich 40 wt . % sio 2 0 . 41 wt . % na 2 o and 59 . 59 wt . % h 2 o ). such studies do result in the layered precursor however not always , and the syntheses are not reproducible with these sources . however , other silicon sources may include alkoxides , fumed silica , colloidal / precipitated silica . fig5 illustrates a schematic flow diagram of the process of as synthesized ics - 3 production . an aqueous solution of the diquat - 5 template is added to the silicon source resulting in a thick template - silicate solution . to this , an aqueous solution including the aluminium and sodium sources is added and the resulting thick gel stirred for 1 - 3 hours . the final gel was autoclaved at 160 ° c . under stirring (˜ 250 rpm ) for 7 - 10 days , preferably 7 - 8 days . the final slurry obtained after the mentioned period was filtered , washed thoroughly with deionized water and dried at 110 ° c . for 6 - 12 hours ( preferably 6 h ). the dried material is the layered as - synthesized ics - 3 . the as - synthesized ics - 3 is converted to the calcined form by heating . as synthesized ics - 3 is heated generally to a temperature in the range 350 ° c .- 600 ° c . for a period of 2 - 20 h , preferably 8 - 10 hours . the preferred temperature is 550 ° c . for a preferred period of 8 h . fig6 provides xrd spectra of the as - synthesized and calcined ics - 3 . table 2 provides details of the important identifying xrd peaks , table 3 provides an intermediate list , whilst table 4 provides a full description . as mentioned previously the as synthesized xrd pattern has the first peak at 2θ ˜ 4 . 439 °, d spacing & gt ; 19 . 5 å ( the first reflection ) followed by the presence of other reflections partly common to zsm - 57 and additional reflections extending from 5 to 50 , with five sharp peaks at 20 of 16 . 378 ± 0 . 050 , 23 . 516 ± 0 . 050 , 25 . 017 ± 0 . 05 , and 26 . 654 ± 0 . 050 and 28 . 488 ± 0 . 05 . table 5 provides details of the important identifying xrd peaks , table 6 provides an intermediate list , whilst table 7 provides a full description . the xrd of the calcined form exhibits two peaks with weak intensities higher angle peaks that are common to zsm - 57 and additional peaks that are characteristics of the new phase arising out of the layered precursor . the first peak at 2θ ˜ 4 . 459 ° is absent in the calcined phase . table 8 compares xrd spectra for zsm - 57 and as synthesized . it can be seen that there are common xrd lines with similar intensities in some cases . however the peaks have different intensities in addition to the peak observed at the lower angle for ics - 3 . ludox hs - 40 ( an aqueous colloidal silica sol solution , ( 40 wt % silica in water ,)) was mixed with distilled water and stirred for 10 min . diquat - 5 was dissolved completely in distilled water . this solution was added to the ludox solution dropwise under vigorous stirring and the mixture was stirred vigorously for 30 min . a clear solution containing aluminium nitrate nonahydrate , sodium hydroxide and water was prepared and added slowly and continuously to the ludox - template mixture under stirring . the thick gel was allowed to homogenize under vigorous stirring at 25 ° c . for 1 h . the final gel was transferred to a 300 ml ss parr autoclave and allowed to crystallize at 160 ° c . for 7 - 12 days and stirred at 250 rpm . the samples were removed periodically and tested for their crystallinity . completely crystalline materials were obtained after 7 days . the slurry was cooled , filtered and washed well with distilled water and dried at 80 ° c .- 110 ° c . for 1 - 2 h . the dried material is the “ as - synthesized ” layered precursor . the molar gel ratio is : a portion of the as - synthesized material was calcined in a static air furnace at 550 ° c . for 8 h . the calcined material is ics - 3 . example 2 : a synthesis recipe with exactly identical amounts were mixed except for 11 . 9 g of diquat - 5 . the amount of the template was doubled . this results in the increase of r / si = 0 . 2 . the final material was found to have a similar pattern mentioned in table 1 . 13 . 7 g of ludox hs40 , 36 . 4 g water , 3 . 9 g diquat - 5 in 7 . 3 g water were used instead of the previous recipe along with 1 . 5 g of aluminium nitrate nonahydrate , 2 . 4 g sodium hydroxide in 14 . 3 g water . si / al h 2 o / si r / si na / si as - synth . ics - 3 47 40 0 . 1 0 . 4 75 % pure layered material was obtained . another phase was present along with the layered phase . the x - ray pattern is given in fig7 . a ) oligomerization of light olefins : oligomerization of olefins is a process to convert light olefins to more value added products . this is conventionally carried out over acid catalysts such as zsm - 5 . the selectivity towards different fractions is mainly dependent on the size of the pore / channels . the products form important raw materials . the pore structure plays an important role . thus , we believe ics - 3 being a layered structure is suitable for the formation of the desired fractions . b ) octane improvement : isomerization of n - alkanes with 5 - 8 carbon numbers results in the improvement of octane numbers in the gasoline fraction eliminating aromatics or any other additives such as mtbe . thus , isomerization of these linear paraffins to branched isomers results in the enhancement of octane numbers . the layered structure , despite fusing of sheets might favor the formation of the highly branched fractions . c ) alkylation of aromatics : alkylation of benzene to cumene is one of the important process , likewise , the alkylation of toluene with methanol leads to p - xylene over the shape - selective zeolites . the product is an important raw material . d ) methanol to olefins / gasoline is a process to convert methanol to olefins or gasolines . thus , the pore topology and the acidity play a very important role in the product formation . e ) isomerization and cracking of linear paraffins lead to fractions that enchance the octane numbers . the above mentioned processes require acid catalysts for effective conversion . ics - 3 owing to its layered structure and acidity due to the aluminum present in the framework is expected to function as the acid catalyst similar to other zeolites . since , it is believed to be structurally related to the zeolite zsm - 57 , it is expected to have properties similar to that of zeolite zsm - 57 . where in the foregoing description reference has been made to elements or integers having known equivalents , then such equivalents are included as if they were individually set forth . although the invention has been described by way of example and with reference to particular embodiments , it is to be understood that modifications and / or improvements may be made without departing from the scope or spirit of the invention . in addition , where features or aspects of the invention are described in terms of markush groups , those skilled in the art will recognise that the invention is also thereby described in terms of any individual member or subgroup of members of the markush group .
