Selective and efficient BTX yield from methanol over low-Si/Al-ratio ZSM-5 impregnated with Mo

Nowadays, aromatic compounds such as benzene (B), toluene (T) and xylene (X), which are known as BTX, are significant chemical intermediates in fine chemical industries, which their commercial demands sharply grow up.1,2 Reforming of petroleum fractions aromatic hydrocarbons are the central source of aromatics while working on new non-petroleum substitute is industrially crucial.3-5 During the recent decades, the research on solid acid catalysts for the conversion of methanol to aromatics (MTA) process has fascinated both scientists and industrial organization, because since methanol is produced from various resources as syngas, natural gas, coal, biomass and any other carbon-based gasifiable feedstock.6,7 Some reports unveiled that the yield of aromatics hydrocarbons production could be improved where the conversion of methanol was executed over the upgraded ZSM-5 zeolite with some metal species. 8 In this work, the catalytic conversion of methanol to aromatic hydrocarbons has been studied over Mo impregnated-low-silica ZSM-5 (Si/Al=11) catalyst with various metal loadings (0, 1, 2 and 4 wt. %).
