Abstract
The conversion of methyl mercaptan was examined over zeolites with MFI, FAU, BEA, MOR, CHA and MWW topology and Si/Al ratio between 10 and 19. At 450 ◦C, over all catalysts, the reagent has been primarily consumed into hydrocarbons and H2S. The crucial variables affecting the hydrocarbon distribution over zeolites were mainly their pore size/architecture and the amount of the acid sites. Over 3D H-ZSM-5, H-β and H-MOR zeolite, many aromatics and only few olefins were produced. In contrast, and analogous to methanol-to- hydrocarbons process, H-SSZ-13 and H-MCM-22 zeolite (containing cages and small pores) mainly produced C2-C3 olefins.
