<p>This is a continuous partial oxidation process for producing fuel gas or synthesis gas from solid carbonaceous fuels. In the process, two separate solid carbonaceous slurry feed streams (with the liquid vehicle being water in one slurry stream and liquid hydrocarbon fuel in the other) along with a separate stream of free-oxygen containing gas which is interposed between said slurry streams, are simultaneously introduced into a reaction zone of a free-flow noncatalytic gas generator where the three streams impinge and mix together to form an atomized dispersion that reacts by partial oxidation at an autogenous temperature in the range of about 1,500 DEG to 3,500 DEG F. and a pressure in the range of about 1 to 250 atmospheres. The effluent gas stream from the reaction zone is split into two streams which are separately cooled and cleaned to produce two separate gaseous streams one gaseous stream saturated with water and the other gaseous stream containing less than 15 mole % water. By the subject mixed mode operation, the weight ratios of water to fuel, oxygen to fuel, and liquid hydrocarbon fuel to total solid fuel may be lowered. This provides a more suitable, and economical gas generator operation.</p> |
