Synthesis and Characterization of HZSM 5 Catalyst for Methanol to Propylene (MTP) Reaction
The effects of different templates on HZSM 5 catalyst morphology and activity in the conversion of methanol to propylene (MTP) were investigated. High silica HZSM 5 catalysts (Si/Al 200) were synthesized successfully using Ludox as silica source and different structure directing agents (SDAs) XRD, SEM, FT IR, NH3 TPD, and N2 adsorption desorption analytical techniques characterized the catalysts. Morpholine shaped nano plate like morphology. TPAOH as template resulted in the high BET surface area (369.4 m2/g) and crystallinity. The HZSM 5 catalysts showed significant catalytic activity. The catalyst with TPABr as template represented the highest propylene selectivity (45% methanol conversion (99.8% and long lifetime (72 h)
