Abstract: Some embodiments of the present disclosure relate to a device comprising a sorbent polymer composite and at least one phosphonium halide. In some embodiments, the device is configured to treat a flue gas stream. In some embodiments, the flue gas stream comprises oxygen, water vapor, at least one SOx compound, and mercury vapor. Some embodiments of the present disclosure relate to a method comprising treating the flue gas stream by: passing the flue gas stream over the device, reacting the oxygen and water vapor of the flue gas stream with the at least one SOx compound on the sorbent polymer composite, so as to form sulfuric acid, and reacting the mercury vapor with the at least one phosphonium halide, so as to fix molecules of the mercuiy vapor to the sorbent polymer composite.

Abstract: The rate of degradation of polymers and polymer blends containing (poly) lactic acid can be increased and controlled by the inclusion of up to 10% (typically less than 1%) by weight of specific additives such as lauric acid or a derivative thereof such as the anhydride.

Abstract: A method for cleaning an exhaust gas containing ammonia and at least one silicon-containing compound selected from the group consisting of silane and chlorosilanes, which comprises contacting the exhaust gas with a scavenger comprising a metal salt which forms tight complexes with ammonia. This ammine-forming metal salt may be immobilized on a porous solid support. Suitable ammine-forming metal salts include the sulfates, nitrates, chlorides, bromides, iodides, and hydroxides of copper, cobalt, iron, and nickel. Suitable supports include materials which are compatible with the gas mixtures being cleaned and the reaction products of the sorption process and which are stable under the conditions of use. Useful support materials include zeolites, aluminosilicates, alumina, silica, silica gel, kieselguhr, and activated carbon.
