Abstract: A method for converting calcium sulfoxy compounds selected from the group consisting of CaSO.sub.x and Ca(HSO.sub.x).sub.2 and their hydrates wherein x is 3 or 4 into calcium carbonate, the method consisting essentially of; converting the Ca(HSO.sub.x).sub.2 compounds into CaSO.sub.x compounds by reacting the Ca(HSO.sub.x).sub.2 compounds with calcium carbonate in the presence of water, thereafter reacting the CaSO.sub.x compounds with ammonia and carbon dioxide in the presence of water to produce NH.sub.4 (HSO.sub.x) wherein x is 3 or 4 and calcium carbonate, thereafter separating the NH.sub.4 (HSO.sub.x) and calcium carbonate and reacting the NH.sub.4 (HSO.sub.x) with carbon to produce ammonia, hydrogen sulfide and carbon oxides.
Abstract: A method is provided wherein nickel molybdenum and cobalt molybdenum catalysts can be used in large scale sulfur hydrogenation reactors without runaway methanation and resulting exotherms while converting organic sulfur compounds to hydrogen sulfide in gas streams which contain significant quantities of carbon monoxide, carbon dioxide, and hydrogen.

Abstract: In a process for hydrocracking heavy carbonaceous materials by contacting such carbonaceous materials with hydrogen in the presence of a molten metal halide catalyst to produce hydrocarbons having lower molecular weights and thereafter recovering the hydrocarbons so produced from the molten metal halide, an improvement comprising injecting into the spent molten metal halide, a liquid low-boiling hydrocarbon stream is disclosed.
