    摘要： Disclosed herein are methods and systems that relate to electrochemically oxidizing metal halide with a metal ion in a lower oxidation state to a higher oxidation state; halogenating an unsaturated hydrocarbon or a saturated hydrocarbon with the metal halide with the metal ion in the higher oxidation state; and oxyhalogenating the metal halide with the metal ion from a lower oxidation state to a higher oxidation state in presence of an oxidant. In some embodiments, the oxyhalogenation is in series with the electrochemical oxidation, the electrochemical oxidation is in series with the oxyhalogenation, the oxyhalogenation is parallel to the electrochemical oxidation, and/or the oxyhalogenation is simultaneous with the halogenation.

    摘要： Provided herein are methods comprising a) treating a slag solid or carbide lime suspension with an ammonium salt in water to produce an aqueous solution comprising calcium salt, ammonium salt, and solids; b) contacting the aqueous solution with carbon dioxide from an industrial process under one or more precipitation conditions to produce a precipitation material comprising calcium carbonate and a supernatant aqueous solution wherein the precipitation material and the supernatant aqueous solution comprise residual ammonium salt; and c) removing and optionally recovering ammonia and/or ammonium salt using one or more steps of (i) recovering a gas exhaust stream comprising ammonia during the treating and/or the contacting step; (ii) recovering the residual ammonium salt from the supernatant aqueous solution; and (iii) removing and optionally recovering the residual ammonium salt from the precipitation material.
