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.

为开发高效、耐用的甲烷脱氢芳构化Mo/H-MFI催化剂，采用了金属硅酸盐基催化剂。在含有三乙氧基乙烯基硅烷的硅化Mo/H-MFI的情况下，表现出比未硅化的更持久的活性。Mo/H-GaMFI在低Ga含量下表现出高而持久的苯产率。结果表明，H-MFI或H-GaMFI的酸性与甲烷脱氢芳构化反应活性有直接关系，抑制MFI骨架中强酸性中心的结焦是提高催化剂脱氢芳构化活性的重要因素。
