Abstract: 1. Process for making synthesis gas (CO + H2 ) by subjecting fine-particulate materials rich in carbon to an autothermal gasification reaction with oxygen, wherein the material rich in carbon having a particle size of 0 - 0,1 mm is injected together with oxygen and, if desired, auxiliary gas into a hot gasification zone, the resulting primary crude synthesis gas containing flying ashes is passed with its inherent thermal energy through a reduction zone charged with the feed materials necessary for effecting an endothermal carbothermal reduction and, increased by the synthesis gas produced during the carbothermal reduction, through a preheating zone arranged immediately above the reduction zone and filled with the same material as this latter zone, and removed with a temperature of 300 up to 1500 degrees C for purification and conversion, and wherein molten reaction product originating from the carbothermal reduction and molten slag are taken from a collecting and post-reaction zone below the reduction zone, which comprises : forming, as the gasification zone, in a heap of loosely aggregated feed material, a cavity or at least a fluidized bed of such loosely aggregated material which is maintained at 1300 - 3000 degrees C ; forming the reduction zone above, and laterally with respect to, the gasification zone ; carrying out simultaneously in the reduction zone a post-gasification reaction during which the steam contained in the primary crude synthesis gas and carbon dioxide undergo reaction with the material rich in carbon to give additional synthesis gas.

Abstract: Mixture for desulfurizing metal melts based on calcium carbide, calcium oxide, alkaline earth metal carbonates, aluminum oxide, chemically unbonded carbon and alkali metal carbonates, if any. The desulfurizing mixture contains 0.3-4.5 wgt % calcium fluoride as an additional constituent and is produced by grinding the individual constituents jointly in a mill over a period of 3-30 minutes.
