【摘要】 本文研究的是在425℃、常压下,通过粘结沸石催化剂,甲醇与氨选择性合成一甲胺的反应。发现ZSM-5及ADHM沸石催化剂对一甲胺的选择率大于88％,甲醇转化率为90％以上。对三甲胺表现出明显的抑制效应可归结于沸石的择形催化效应。更多还原

【Abstract】 The selective Production of monomethylamine (MMA) from methanol and ammonia was studied over some adhesive zeolites at temperature of 425℃ under ambient pressures. ZSM—5 and ADHM zeolites catalysts were found to show considerable selectivity for MMA around 88% at the conversion level of over 90%. Indcating effective suppression of trimethylamine(TMA) format ion over the zeolites, which is due to the shape selective catalysis of zeolites.更多还原
