Investigation on the Catalysts and Reaction Process for the Methanol Synthesis at Lower-Temperature in Liquid Phase

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.
