IN THE CATALYTIC PRODUCTION OF HYDROCARBONS FROM CARBON MONOXIDE AND HYDROGEN, A PROCESS WHICH COMPRISES GENERATING A SYNTHESIS GAS CONTAINING CARBON MONOXIDE AND HYDROGEN BUT SUBSTANTIALLY NO OXYGENATED HYDROCARBONS IN A GAS GENERATION ZONE UNDER CONDITIONS, INVOLVING PARTIAL COMBUSTION OF HYDROCARBONACEOUS MATERIAL AT A TEMPERATURE IN ORDER OF 2100* F. AND HIGHER WITH OXYGEN, WHICH RESULT IN A GENERATOR EFFLUENT GAS HAVING ENTRAINED THEREIN SMALL AMOUNTS OF DIFFICULTLY REMOVABLE SOLID CARBONACEOUS PARTICLES FORMED IN SAID GENERATION ZONE, SCRUBBING SAID PARTICLES FROM SAID EFFLUENT GAS WITH LIQUID OB-
