对催化体系的研究表明,甲醇的合成包括两个步骤:甲醇羰基化为甲酸甲酯和甲酸甲酯的连续氢解(使用氢气除去取代基)为甲醇,导致一个甲醇分子的净增益。反应可以同时进行,在一个反应器(单阶段过程),或在两个独立的反应器(两步法);本文讨论了这两种方法,并描述了一些主要的障碍,以克服,以开发一个从根本上改进的过程。
The investigations into the catalytic systems revealed that the synthesis of methanol consists of two steps: methanol carbonylation to methyl formate and the successive hydrogenolysis (removal of a substituent using hydrogen) of methyl formate to methanol, leading to a net gain of one molecule of methanol. The reactions can be carried out concurrently, in a single reactor (single-stage process), or in two separate reactors (two-step process); this article discusses both processes and describes some of the major obstacles to overcome in order to develop a radically improved process.
