US3840354A - Three-stage gasification of coal - Google Patents
A process for the production of methane-rich fuel gas by the gasification of coal in three stages. In the first stage, partially gasified char recycled from the process is reacted with oxygen and superheated steam at pressures greater than 50 atmospheres and temperatures greater than 2,500*F. to yield a first stage synthesis gas containing hydrogen and carbon oxides.
