Methanol is predominantly produced by a coaltomethanol process in China. However, this process is criticized by high CO 2 emissions because of the high carbon contents of coal. The high CO 2 emission and low resource utilization efficiency greatly weaken the competitiveness of the coalto methanol industry. Coke oven gas, one of the hydrogenrich resources, is used as fuel or directly ...

A number of technologies were developed over the years to produce methanol, including several feedstocks, such as natural gas, coal, and biomass or CO 2 —the latter directly recoverable from the atmosphere [3,7].. From an historic point of view, methanol production processes took place before the 1660s (by Robert Boyle).

The coaltomethanol process can be divided into four major cost areas: coal purchase, coal gasification, gas preparation, and methanol synthesis. The contribution to the plantgate cost was estimated for each area except for coal purchase by dividing the plant capital and operating costs among the areas and calculating a product price for each.

Gasification is a thermochemical process for the conversion of a solid organic material, typically coal or biomass, into syngas. From a chemical point of view, gasification occurs due to the partial oxidation of a solid material at temperatures of 700900 °C by means of a gasifyingoxidant agent, such as air, oxygen, steam or carbon dioxide.
