Abstract
The disclosure provides a gasification process for the production of a methane-rich syngas at temperatures exceeding 700° C. through the use of an alkali hydroxide MOH, using a gasification mixture comprised of at least 0.25 moles and less than 2 moles of water for each mole of carbon, and at least 0.15 moles and less than 2 moles of alkali hydroxide MOH for each mole of carbon. These relative amounts allow the production of a methane-rich syngas at temperatures exceeding 700° C. by enabling a series of reactions which generate Hand CH, and mitigate the reforming of methane. The process provides a methane-rich syngas comprised of roughly 20% (dry molar percentage) CHat temperatures above 700° C., and may effectively operate within an IGFC cycle at reactor temperatures between 700-900° C. and pressures in excess of 10 atmospheres.
