I have a gentle question: How is methanol produced (the manufacturing process)?
Thread Content
As the title suggests, I’m an amateur and would like to know: how is methanol produced (the manufacturing process)? I hope for your advice!

This book is complex enough for a layperson: L
In China, coal is mainly used, while abroad natural gas is generally used. The specific production process can be found by consulting relevant materials; searching for the triol synthesis method will provide the necessary information·
There is a lot of information on the specific theoretical principles in forums; in simple terms, it is synthesized through the catalytic action of a catalyst, using CO and H2 produced by the combustion of coal (or natural gas, oil), in certain proportions.
If methanol is produced from coal, it’s actually similar to the process of producing ammonia from coal. First, the coal is vaporized to produce gas; thereafter, the raw gas is purified and compressed before being sent to methanol synthesis. Purification: To obtain qualified methanol synthesis gas. The raw gas needs to be desulfurized (to remove sulfides from the gas, mainly hydrogen sulfide), shifted (to adjust the ratio of carbon monoxide to carbon dioxide), decarburized (to remove carbon dioxide), and further purified (using adsorbents to eliminate trace amounts of sulfides in the raw gas). Compression: Used to adjust the pressure of gases, in order to meet the pressure requirements of various production processes.
