    Abstract: A method of recovering aqueous N-Methylmorpholine-N-Oxide solution used in production of Lyocell fiber comprises following steps. Bleach means for decoloring coloration in aqueous NMMO solution via alternate blow-mixing adsorption mode and static suspending adsorption mode reiteration. Filtration means for purifying the activated carbon powder and impurities by two filtering stages of first coarse filtering stage and second fine filtering stage. Concentration means for intensifying aqueous NMMO solution to obtain a condensed aqueous solution without NMMO solvent and a concentrated aqueous solution with NMMO solvent respectively by a sequential multi-stage evaporating system. Refinement means for purifying aqueous NMMO solution with promoting purity of concentrated aqueous solution to obtain required recovered aqueous solution by adding suitable agents in the redox reactions involved. Owing to streamlining and simplicity, the method not only has better competitiveness from promoted recovery cost, efficiency and quality but also meets regulations of environmental protection.

    Abstract: The invention provides a method to transform large quantities of fiber glass waste into useful ceramic products by a low-cost manufacturing process. The method consists of reducing the fiber glass waste into a glass powder; mixing the glass powder with additives into a glass-additives mixture; granulating the glass-additives mixture into granulated particles; forming the granulated particles into a green ceramic article; and heating the green ceramic article into the ceramic product. Water and clay can be included in the processing. Only one firing step is needed with a low peak firing temperature of about 700° C. to about 1000° C. The method conserves energy and natural resources compared to clay-based traditional ceramic manufacturing. High-quality impervious ceramic products can be produced by the invention.

    Abstract: This invention relates to methods for controlling the oxidation of hydrocarbons to dibasic acids, in the presence of a catalyst and a monobasic acid, by removing the catalyst from the reaction mixture, outside the oxidation zone, after the oxidation has taken place at least partially. Initially, the catalyst is partially precipitated and removed by reducing the water level in the reaction mixture and/or subjecting the reaction mixture to a temperature, at which or over which catalyst precipitates. After the initial partial precipitation of the catalyst, the remaining catalyst is subjected to a thermal treatment, during which at least part of the monobasic acid is removed leaving behind molten dibasic acids, in which, at least a major part of the remaining catalyst is precipitated, and it is removed. A minor part of remaining catalyst is removed by methods, which include but are not limited to ion exchange, precipitation with a base or appropriate salt, and electrodialysis. The precipitated catalyst in the three removal stages may be recycled in miscellaneous ways. The dibasic acid(s) may be removed at least partially before or after any catalyst precipitation stage.

    Abstract: A simple and efficient process is provided for disposing of easily airborne carbon fibers by subjecting them to an aqueous solution of an alkali metal or alkaline earth metal hypohalogenite at an elevated temperature for a period of time sufficient to substantially destroy the fibrous configuration of said fibers. In a preferred embodiment, carbon fibers are contacted with a solution of sodium hypochlorite (approximately 5 to 6 percent active chlorine concentration by weight based on the weight of the solution) at a temperature of between about 50.degree. and about 60.degree. C. for between about 1 and about 12 hours.
