Abstract: 1. Process for generating synthesis gas (CO + H2 ) by subjecting fine particulate materials rich in carbon to an autothermal gasification reaction with oxygen optionally in the presence of an additional gas, which comprises : injecting coal dust having a particle size of up to 0.1 mm and the oxygen and optionally the additional gas into an empty gasification zone maintained at 2000 to 2600 degrees C ; passing the resulting flue dust-containing crude synthesis gas with ist inherent thermal energy through a reduction zone having the feed materials necessary for initiating an endothermal carbothermal reduction with formation of ferrosilicon, calcium carbide, elementary phosphorus or metallic iron placed therein, and then passing it and the synthesis gas produced during the carbothermal reduction through a directly connected preheating zone having the same materials as this latter zone placed therein ; removing the synthesis gas at a temperature of 300 up to 1500 degrees C for purification and conversion ; and removing, below the reduction zone, as fused reaction product originating from the carbothermal reduction, ferrosilicon, calcium carbide or metallic iron and fused slag from a collecting and post-reaction zone.

Abstract: The invention relates to a process comprising the cooling and comminuting of molten calcium carbide, wherein a molten stream of calcium carbide is tapped off from a furnace at 1900 DEG to 2100 DEG C., cooled and comminuted. More particularly, the molten calcium carbide is initially comminuted into droplets and the droplets are cooled to less than 200 DEG C. The process can be carried out with the aid of an apparatus comprised of a heatable or coolable feed duct, a nozzle for comminuting the molten stream, and a series of fluidized bed cooling zones.
