Abstract

Hydrodeoxygenation (HDO) of guaiacol in a batch-type reactor at 40 bar and 250 °C was investigated using six different catalysts, Pt/HZSM-5, Pt/Mesoporous Beta, Pt/HBeta, Pt/MMZBeta, 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/MMZBeta, 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 CC coupling reactions.
