Hydrodeoxygenation of guaiacol over Pt loaded zeolitic materials
Abstract Hydrodeoxygenation (HDO) of guaiacol in a batch type reactor at 40 bar and 250 degC was investigated using six different catalysts, Pt/HZSM 5, Pt/Mesoporous Beta, Pt/HBeta, Pt/MMZ Beta Pt/Al MCM 48, and Pt/Si MCM 48. Among various catalysts, Pt/Mesoporous Beta and Pt/HBeta, which have both large pores and strong acid sites, showed guaiacol conversions larger than 90% The main product species of HDO of guaiacol was cyclohexane. Meanwhile, Pt/Al MCM 48 and Pt/MMZ Beta which are mesoporous catalysts with weak acid sites, led to lower guaiacol conversions than Pt/Mesoporous Beta and Pt/HBeta and the main product components were cyclohexane and 1,1 bicyclohexyl resulting from C C coupling reactions.
