Abstract

The present invention describes a process for producing synthesis gas by partial oxidation of carbon-containing particles suspended in water with oxygen at elevated pressures and temperatures of 1000.degree. to 1600.degree. C. Three substance streams are added separately but simultaneously to the reactor. The inner substance stream consists of oxygen or a mixture of oxygen and synthesis gas. The middle substance stream forms a carbon-water suspension, and the outer substance stream carries oxygen or oxygen-containing gases. Due to the fact that these three substance streams intersect at an acute angle, an ideal distribution of the suspension with the gas streams is achieved and an optimum reaction course is ensured. In order to be able to compensate requirement fluctuations during continuous operation, the outlet opening for the carbon-water suspension and the outer gas stream can be correspondingly adapted in a continuous and independent manner.
