An improved continuous partial oxidation process for producing clean synthesis or fuel gas and by-product steam 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 hot immersion fluid is continuously removed from the immersion vessel and cooled to a temperature in the range of about 300°to 850°F. but above the dew point of the water in the process gas stream in an external heat exchanger, such as a steam generator. High pressure by-product steam may be produced thereby. A portion of the cooled immersion fluid, optionally in admixture with a hydrocarbonaceous scrubbing fluid of a similar composition obtained subsequently in the process may be recycled to the immersion vessel and optionally to the gas generator as at least a portion of the hydrocarbonaceous fuel feed.

A continuous process for producing clean synthesis or fuel gas comprising: 1. introducing into the reaction zone of a free-flow, unpacked gas generation zone as feed materials a dispersion of particulate carbon in liquid hydrocarbonaceous fuel, a stream of free-oxygen-containing gas selected from the group consisting of air, oxygen-enriched air, i.e. at least 22 mole % oxygen, and substantially pure oxygen, i.e. at least 95 mole % oxygen, wherein the ratio of free-oxygen in the free-oxygen-containing gas to carbon in the feedstock (O/C atom/atom) is in the range of about 0.6 to 1.5, and optionally a temperature moderator selected from the group consisting of H2O, CO2, flue gas, a portion of cooled and recycled effluent gas from the gas generator, and mixtures thereof, and reacting said feed materials by partial oxidation at a temperature in the range of about 1300°to 3000°F. and a pressure in the range of about 1 to 250 atmospheres, thereby producing an effluent gas stream containing H2, CO, CO2, H2O, particulate carbon, and optionally at least one gas from the group H2S, COS, N2, A and CH4; 2. cooling the effluent gas stream from (1) to a temperature in the range of about 300°to 900°F. but above the dew point of water in said gas stream and simultaneously removing said entrained particulate carbon by discharging said effluent gas stream directly into a body of hot immersion fluid contained in a quench zone and comprising a dispersion liquid hydrocarbonaceous fuel and particulate carbon, and removing from said quench zone a clean gaseous stream comprising H2CO, CO2, H2O and optionally at least one material from the group particulate carbon, H2S, COS, N2, A, and C1 -C10 hydrocarbons; 3. cooling at least a portion of the hot immersion fluid from (2) to a temperature in the range of about 300°to 850°F. by indirect heat exchange with water in an external heat exchange zone thereby producing by-product steam and cooled immersion fluid, and recycling at least a portion of said cooled immersion fluid to said quench zone; and 4. introducing a portion of said hot immersion fluid from (2) or a portion of said cooled immersion fluid from (3) into said gas generation zone in (1) as at least a portion of said dispersion of particulate carbon in liquid hydrocarbonaceous fuel.
