To develop the Mo/H-MFI catalyst for methane dehydroaromatization with high and durable activity, metallosilicate-based catalysts have been employed. In the case of silylated Mo/H-MFI with triethoxyvinylsilane, more durable activity is shown than non-silylated ones. Mo/H-GaMFI shows high and durable benzene yield at low Ga contents. It is concluded that acidic property onto H-MFI or H-GaMFI directly relates to the catalytic activity for methane dehydroaromatization, and inhibition of coking onto strong acid sites in the MFI extraframework is important to enhance the dehydroaromatization activity.
