Marion, C P; Jahnke, F C

Heavy liquid hydrocarbon fuel containing high metal concentrations and all of the soot rich in metal values that is produced in the system are feedstocks in a partial oxidation process. Three free-flow noncatalytic partial oxidation gas generators are simultaneously operated for the simultaneous continuous production of two streams of cleaned, raw synthesis gas having high and low H/sub 2/O/dry gas mole ratios, respectively. In the process, all of the hot, raw synthesis gas containing entrained particulate carbon and ash that is produced by the first two gas generators is quench cooled and scrubbed with water in separate quench tanks. Simultaneously, as stream of hot raw synthesis gas containing entrained particulate carbon and ash is produced by a third gas generator and cooled in a convection-type gas cooler without fouling and plugging of the tubes. All of the soot recovered from the quench cooling and scrubbing waters in the process is recycled to the first and/or second gas generator in admixture with the heavy hydrocarbon fuel.
