主 题：Methane conversion Methanol Co-reaction Acidity HZSM-5
摘 要：A co-reaction of methane with methanol over zeolite catalysts has emerged as a new approach to the long-standing challenge of methane ***,the effect of catalyst acid properties on the co-reaction has been rarely *** this study,a series of HZSM-5 zeolites with comparable diffusion abilities and various acidities were synthesized directly through steaming with 100%water vapor at 693 *** co-reaction of methane and methanol was subsequently ***?nsted acidity at 0.262 mmol/g was detected to reach the maximum methane conversion of 5.42%at 673 K,which was also the odd point in the relationship between acid concentration and C4 hydrogen transfer ***,the influence of methanol feed was investigated over parent and steamed ZSM-5 catalyst,with results showing that excessive acid sites or methanol molecules reduce methane *** is proposed that acid sites adsorbed with methanol molecules construct the methane activation ***,a proper design of zeolite acidity should be achieved to obtain higher methane conversion in the co-reaction process.
