Marion, C P

A process is described for recovering particulate carbon from the effluent gas stream from a partial oxidation synthesis gas generator by scrubbing the effluent gas with water in a scrubbing zone to form a carbon-water dispersion, by mixing said dispersion in a mixing zone with liquid organic extractant comprising a mixture of the liquid organic by-products from the oxo or oxyl process, optionally in admixture with a light liquid-hydrocarbon fuel fraction, to produce a clarified water layer and a carbon-extractant dispersion, by separating and recycling said clarified water to said scrubbing zone, by separating said carbon-extractant dispersion and introducing same into a fractional-distillation zone in admixture with fresh liquid-hydrocarbon fuel feedstock, by recycling a light fraction from said distillation zone to said mixing zone as said liquid organic extractant, and by introducing a pumpable bottoms carbon slurry from said distillation zone into said synthesis-gas generator as at least a portion of the fuel. 16 claims, 2 figures.
