Abstract: Process for treatment of black liquors from kraft pulp mills wherein black liquor is heated, in the absence of added free oxygen, under pressure at a temperature in the range of 450 to 700* F. for a period of 0.5 minutes to 6 hours to form a solid granular coke product which is separated from the resulting liquid to yield an aqueous liquid effluent suitable for reuse in the pulp making process.

Abstract: PETROLEUM COKE IS PURIFIED OF SULFUR AND METALLIC IMPURITIES BY HYDRODESULFURIZATION WITH SYNTHESIS GAS FOLLOWED BY PASSING THE RESULTING SYNTHESIS GAS, WHICH IS RELATIVELY RICH IN HYDROGEN SULFIDE, IN CONTACT WITH THE COKE, AT A TEMPERATURE AND PRESSURE AT WHICH THE HYDROGEN SULFIDE CATALYZES THE REACTION OF THE METALLIC IMPURITES WITH CARBON MONOXIDE TO FORM GASIFORM METALLIC CARBONYLS WHICH CAN BE PHYSICALLY SEPARATED FROM THE COKE.

Abstract: PURIFICATION OF PETROLEUM COKE HIGH IN SULFUR AND CONTAINING METALLIC IMPURITIES BY PASSING AN EXCESS OF SYNTHESIS GAS IN CONTACT WITH THE PREOXIDIZED COKE AT A TEMPERATURE AND PRESSURE AT WHICH THE CARBON MONOXIDE OF THE SYNTHESIS GAS IS CAUSED TO COMBINE WITH THE METALS, UNDER THE CATALYTIC EFFECT OF THE SULFUR IN THE COKE, TO FORM GASIFORM METAL CARBONYLS WHICH ARE READILY SEPARATED. THE RESULTING SYNTHESIS GAS IS THEN USED TO HYDRODESULFURIZE THE COKE UNDER APPROPRIATE CONDITIONS.
