英文摘要	enhanced performance of methane dehydro-aromatization reaction (mda) were achieved on a mo-based hzsm-5 zeolite catalyst in which hzsm-5 were pretreated by a proper amount of nh4f (mo/hz(f)). the results of nh3-tpd and al-27 mas nmr demonstrated that the number of bronsted acid sites decreased on the hzsm-5 zeolite and mo/hzsm-5 catalyst after nh4f treatment. tga and tpo measurements showed that the mo/hz(f) catalysts were highly resistant to coke deposition, which resulted mainly from the elimination of the bronsted acid sites after the pretreatment of the hzsm-5 zeolite with nh4f.
