An improved continuous partial oxidation process is claimed for producing clean synthesis or fuel gas from a hydrocarbonaceous fuel feed is disclosed wherein hot gases from the process are simultaneously cooled and cleaned by direct contact with hydrocarbon oil. Thus, the effluent gas stream from the reaction zone of the gas generator is cooled and cleaned by discharging the gas stream directly into a relatively large body of hot liquid hydrocarbon immersion fluid. For example, the immersion fluid may be a dispersion of liquid hydrocarbonaceous fuel such as petroleum oil and particulate carbon which is contained in a separate immersion vessel. A portion of the immersion fluid is continuously removed from the immersion vessel and is cooled in an external cooler to a temperature in the range of about 300 to 850/sup 0/F but above the dew point of the water in the process gas stream. Portions of the cooled immersion fluid optionally in admixture with scrubbing fluid obtained subsequently in the process are recycled to the immersion vessel, and optionally to the gas generator as at least a portion of the hydrocarbonaceous fuel feed. In another embodiment, a portion of the immersion fluid removed from the immersion vessel may be introduced into the gas generator as at least a portion of the feed without first being passed through a cooler. The effluent gas stream leaving said immersion zone may be subjected to additional cleaning by being scrubbed with said scrubbing fluid comprising make-up hydrocarbonaceous fuel and particulate carbon in a separate scrubbing zone. The clean product gas comprises H/sub 2/, CO, CO/sub 2/, H/sub 2/O and, optionally at least one material from the group H/sub 2/S, COS, N/sub 2/, A, and C/sub 1/--C/sub 10/ hydrocarbons. 13 claims, 1 figure.
