摘要
本文综述了低温液相合成甲醇的发展历史、研究现状和目前存在的关键技术问题。重点讨论了催化剂体系和活性中心、催化反应过程和工艺、反应机理和失活机理以及催化剂循环再生的研究。与传统的甲醇合成方法比较 ,液相低温甲醇直接合成方法具有单程转化率高 (90 %以上 ) ,生产成本低 ,产品品质优 ,反应条件温和等优点。共引用参考文献 36篇。
The history and development of methanol synthesis at lower-temperature in liquid phase (MSLTLP), the research situations, and the present key problems of the technology to be solved are reviewed in this paper. The following topics are especially discussed: the catalyst systems, active sites, reaction pathways and processes, reaction mechanism and catalyst deactivation mechanism, the catalytic re-cycle and regeneration. Comparing the traditional techniques for methanol synthesis, there are a few advantages for the MSLTLP method: the high simple-pass conversion(more than 90%), the low production cost, the high grade product quality, the mild and temperate reaction conditions. 36 references are cited.
