methanol production from lignite coal

Costs to Convert Coal to Methanol

With presently available transportation, the lowest delivered prices were for methanol production based in the southern lignite coal region. If new methanol-compatible pipelines were to be constructed, the lowest delivered prices would be for production based in the western subbituminous coal region.

lignite gasification increases costs of coal

Lignite is the lowest rank of coal and has the lowest energy content. Lignite is crumbly and has high moisture content. Lignite accounted for about 9% of U.S. coal production in 2017. Subbituminous coal has a higher heating value than lignite. Subbituminous coal typically contains 35%–45% carbon, compared to 25%–35% for lignite. [PDF]Get Price
