Study on highly active and stable catalysts for methanol/higher alcohols synthesis from syngas

Abstract

随着对原油消耗的日益关注,发展煤基替代能源成为我国“十二五”规划能源发展的重要战略,其中煤基合成气制低碳醇醚燃料不仅可以减少我国对石油进口的依赖,还能摆脱“石油危机”。醇醚燃料包含甲醇、二甲醚和乙醇等低碳醇组分,不仅可以作为燃油的清洁替代品和添加剂,还是重要的化工原料。合成气可以由煤气化得来,目前低碳醇合成催化剂存在活性差、C2+醇选择性低和催化剂易失活等问题,因此开发高活性、高稳定性的催化剂迫在眉睫。本文研究了两类催化剂:1)CuCo基低碳醇合成催化剂;2)PdZn基甲醇/二甲醚合成催化剂。本文的目的是分别对这两类催化剂构建其构效关系。 一、CuCo基催化剂研究结果 分别采用浸渍法和水热...Along with the increased concerns on the depleting crude oils, the development of clean coal-based alternative process for fuel productions became the important strategy during National “12th five-year plan”. The low carbon alcohol-ether fuels synthesis from coal-based syngas can reduce our dependence on oil imports and break away from the “oil crisis” in the future. The low carbon alcohol ether f...学位:工学硕士院系专业:化学化工学院_化学工程学号:2062014115141
