    Abstract: A method is disclosed for the manufacture of particles composed of an intimate admixture of barium or strontium ferrite and ferric oxide from a chloride solution containing barium or strontium ions and ferrous ions by a pyrohydrolysis reaction. The presence of carbon dioxide in the heated atmosphere in which pyrohydrolysis of an admixture of alkaline earth metal chloride and iron chloride is carried out has been discovered to substantially decrease the temperature required for reaction to occur.

    Abstract: Systems are disclosed for making and using micro-porous particulates at least partially composed of metal sulfides, particularly alkaline earth metal and transition metal sulfides, as sorbents for removal of mercury from flue gas. Calcium sulfide micro-porous powders derived from the high temperature reduction of calcium sulfate and calcium sulfite are disclosed to be reactive substrates for a group of sorbents for adsorption of mercury from coal combustion flue gases produced by the utilities industry, as well as from natural gas and gaseous and liquid hydrocarbons. The sorbents are useful for cost-effectively adsorbing elemental mercury and oxidized mercury species such as mercuric chloride from flue gases, including those containing acid gases (e.g., SO.sub.2, NO and NO.sub.2, and HCl), over a wide range of temperatures.

    Abstract: In the recycling of Nylon 6 and Nylon 6,6 polyamides from post-consumer or post-industrial waste, a process is disclosed to separate Nylon 6 and Nylon 6,6 polyamides from commingled polyolefin waste components, particularly polypropylene, by admixing the waste with an ester solvent composition and heating the admixture to a temperature above the melting temperature of the contained polyolefins to form an ester solvent composition further containing dissolved polyamide polymer and a separate immiscible liquid polyolefin phase. The ester solvent composition preferably contains ethylene carbonate, propylene carbonate, butylene carbonate, or mixtures thereof.

    Abstract: A process for the continuous production of alkaline earth metal hydroxide by continuously providing an aqueous alkaline earth metal halide solution to the anode compartment and an aqueous alkaline earth metal hydroxide solution or water to the cathode compartment of an electrolytic cell in which an anode and a cathode are maintained in separate anode and cathode compartments, respectively, by a stable, hydrated, cation selective, hydraulically impermeable, electrically conductive membrane interposed between said anode and said cathode; electrolyzing the alkaline earth metal halide solution; and continuously removing alkaline earth metal hydroxide solution and hydrogen from the cathode compartment and halogen from the anode compartment. The membrane is a film of a fluorinated polymer with pendant side chains containing sulfonyl groups present as ion exchange sites and attached to carbon atoms which have at least one fluorine atom attached thereto. In another embodiment the membrane is a laminate of two such polymers differing in equivalent weight.
