Donath Ernest E: Three-stage gasification of coal. The United States of America represented by the Secretary of the, Price Jr Stanley J, October 8, 1974: US3840354 (16 worldwide citation)

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.degree.F. ...

Donath Ernest E: Two-stage downflow gasification of coal. The United States of America represented by the Secretary of the, Price Jr Stanley J, October 29, 1974: US3844733 (15 worldwide citation)

A process for the two-stage downflow gasification of coal to produce a methane rich fuel gas. In a first stage, partially gasified char recycled from a second stage is reacted with super-heated steam and oxygen to produce a first stage synthesis gas. In the second stage, the first stage synthesis ga ...
