Coal to Methanol

This gas, which consists chiefly of carbon monoxide and hydrogen, is used to feed the chemical plants. Methanol is produced in one plant by the Lurgi low-pressure gas-phase process. The syngas needed for these plants is produced by two high-pressure gasifiers. High-sulfur coal is ground and fed to these gasifiers as a water slurry with pure oxygen.

Methane production from coal by a single methanogen

Oct 14, 2016Much of the methane in coal comes from microbial methanogenesis. Mayumi et al. characterized a strain of Methermicoccus shengliensis that, unexpectedly, is capable of making methane from the dozens of methoxylated aromatic compounds found in a variety of coal types (see the Perspective by Welte).

Based on the dry basis alone, the Martin Lake Texas Lignite is the best choice. However the coal received with high percentage moisture increases the amount of coal required. Martin Lake coal has the highest percentage of moisture, which will require a higher amount of coal to make the required methanol, which results in higher production costs.
