Abstract Process for the production of synthesis gas from hydrocarbon liquids by direct partial oxidation with oxygen-containing gas and steam wherein oil containing carbon recovered from the process is supplied to a flow-type synthesis gas generator maintained at an autogenous temperature within the range of 1,800-3,000* F., effluent gas from the reaction zone is cooled by indirect heat exchange to a temperature above the dew point of the product gas stream, and the product gas stream scrubbed with liquid hydrocarbon at a temperature above the dew point of water vapor contained in said product gas and below the boiling point the hydrocarbon liquid and resulting hydrocarbon liquid containing recovered carbon is supplied to the gas generation zone as part of the feedstock for the production of synthesis gas.
The process of claim 1 with the added steps of scrubbing the effluent gas stream leaving said gas-liquid separating zone with water at a temperature in the range of about 100* to 500* F. and in the amount of about 1 to 10 gallons of water per thousand cubic feet of effluent gas thereby removing any remaining particulate carbon, condensing hydrocarbon oil vapors from said effluent gas stream and producing a mixture of water and oil, vaporizing a portion of said water and oil mixture in a heating zone forming a steam-oil vapor mixture, and introducing said steam-oil vapor mixture into said reaction zone of the gas generator as at least a portion of said steam and liquid hydrocarbon fuel.
