摘　　要：以A 6型催化剂为基础 ,采用连续进料、绝热固定床反应器合成和五塔分离工艺的甲醇气相胺化制甲胺技术的工艺流程合理 ,能充分利用热能 ;改善了气流分布 ,使催化剂性能得到充分发挥 ;一甲胺、二甲胺、三甲胺的产量可以根据需要自由调节。A 6型催化剂的催化反应性能为二甲胺选择性达 2 7 0 %。Based on A 6 catalyst, the technology for methylamine production by methanol gas amination has been developed using continual feeding, adiabatic fixed bed reactor and five column separation. This process exhibits advantages of reasonable process flow diagram, making full utilization of heat energy; catalyst capability fully playing well caused by improving gas flow distribution and controllable freely output of monomethylamine, dimethylamine and trimenthylamine. The catalytic capability of A 6 catalyst shown as dimethylamine selectivity is 27 0%.
