Abstract: A process is provided for continuously controlling the hydrocarbon heat content and flow rate of a partial oxidation unit feed-gas stream under conditions where the composition and hence the hydrocarbon heat content of the feed-gas stream is subject to variation. The hydrocarbon heat content of the incoming gases is continuously measured and compared against a design hydrocarbon heat content. An evaluating means calculates whether a moderator is required to decrease the hydrocarbon heat content to the design hydrocarbon heat content or a supplemental high hydrocarbon heat content gas is required to increase the hydrocarbon heat content to the design hydrocarbon heat content. The process utilizes recycle synthesis gas as a moderator.

Abstract: Abundant low cost low rank coal may now be gasified by partial oxidation or burned in a furnace or boiler. About 30 to 45 parts by wt. of comminuted low rank coal is mixed and reacted in the reaction zone of a partial oxidation gas generator with a free-oxygen containing gas and (a) about 1 to 3 parts by wt. of a residual fuel oil, and (b) about 70 to 55 parts by wt. of water. The hot effluent stream of synthesis gas, reducing gas or fuel gas from the partial oxidation gasifier may be purified to provide a gas stream which will not pollute the environment.
