United States Patent Application: 0090126259
We've documented many times, that, through an initial process of gasification, followed by catalyst-promoted chemical condensation, Coal can be converted into the valuable alcohol, Methanol.
Such an operation is, in fact, being conducted on a profitable commercial basis by Eastman Chemical Company in Kingsport, Tennessee; again as we have documented, for just one example, in:
Coal to Methanol - Eastman & Air Products | Research & Development; which concerns Eastman's: "Commercial-Scale Demonstration of a Liquid-Phase Methanol Process; Abstract: The Eastman Chemical Company operates a coal gasification complex in Kingsport. Tennessee. The primary output of this plant is carbonylation-derived acetic anhydride. The required methyl acetate is made from methanol and acetic acid. Methanol is currently produced from syngas ... . (Syngas made from Coal.) An Air Products/Eastman joint venture, with partial funding from the Department of Energy under the Clean Coal Technology Program, has been formed to build a demonstration-scale liquid-phase methanol plant ... . In an array of integrated plants, coal is gasified and the resulting synthesis gas purified to a high degree. 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".
