DESULFURIZING MIXTURE BASED ON MAGNESIUM GRAINS BEING COATED WITH AN INORGANIC COMPOUND AND GRAINS OF CALCIUM CARBIDE

摘要

In a desulphurising mixt. based on mineral-coated magnesium particles and calcium carbide particles with an average particle size proportional to the average densities of the particles. The mineral coating may consist of a slag of compsn. 2CaO.SiO2 or calcium carbide pref. of up to 80 microns particle size. The calcium carbide particles pref. comprise agglomerated carbide fines. The mineral coating and/or the agglomerated carbide particles pref. contain an animal, vegetable or mineral oil or fat as binder, pref. based on hydrogenated ricin oil. The calcium carbide particles may be agglomerated with a coal tar binder. Pref. the mixt. contains less than 38 wt.% magnesium.
