英文摘要: It is found that the water in cofeed gas had three kinds of effects on the oxidative coupling of methane: 1) decrease in the temperature of catalyst bed and increase in the selectivity of coupling products 2) a rise in the temperature of catalyst bed 3) oscillating in the temperature of catalyst bed. Those mainly depend on the properties of the catalysts and operation conditions. Mie have developed the radial now fixed bed reactor for the oxidative coupling of methane, which may maintain the good performance of catalysts an the larger test scale. it is proposed that the methane aromatization on the Mo/ZSM-5 zeolite catalyst without using oxidants is a structure sensitive reaction and the deactivation of the catalyst is initially related to the reduction of the Mo species at higher valence and loss of surface oxygen. The equation of the coke forming is listed.
