  • Patent number: 8541638
    Abstract: Disclosed herein are processes in which precipitation permits removal of metal halides (e.g. AlCl3) from ionic liquids. After precipitation, the precipitated metal halides can be physically separated from the bulk ionic liquid. More effective precipitation can be achieved through cooling or the combination of cooling and the provision of metal halide seed crystals. The ionic liquids can be regenerated ionic liquid catalysts, which contain excess metal halides after regeneration. Upon removal of the excess metal halides, they can be reused in processes using ionic liquid catalysts, such as alkylation processes.

  • Publication number: 20100094070
    Abstract: Bimetallic, supported catalysts for production of 1-hexene from ethylene are manufactured by impregnating a porous, solid support material with at least one catalytic chromium compound and at least one catalytic tantalum compound. The bimetallic, supported catalysts have high catalytic turnover, high selectivity for 1-hexene production, a low tendency for metals to leach from the catalysts during manufacturing and use compared to catalysts manufactured using known techniques. Moreover, the catalysts can be reused in multiple synthesis runs. High turnover, high selectivity, and reusability improve yields and reduce the costs associated with producing 1-hexene from ethylene, while the absence of metal leaching reduces the potential environmental impacts of using toxic metal catalysts (e.g., chromium).

    Abstract: A catalyst composition is disclosed that includes chromium, oxygen, and at least two of gold, silver, and palladium as essential constituent elements. The amount of modifier metals (gold, silver, and/or palladium) in the composition is from about 0.05 atom % to about 10 atom % based on the total amount of chromium and modifier metals. Also disclosed is a process for changing the fluorine distribution (i.e., content and/or arrangement) in a hydrocarbon or halogenated hydrocarbon in the presence of the catalyst composition; and methods for preparing said catalyst composition. One preparation method involves (a) co-precipitating a solid by adding ammonium hydroxide (aqueous ammonia) to an aqueous solution of soluble salts of modifier metals and a soluble chromium salt that contains at least three moles of nitrate per mole of chromium in the solution and has a modifier metal content of from about 0.

  • Publication number: 20080103332
    Abstract: A method of manufacturing PTA oxidized catalyst with lower corrosion, the oxidized catalyst is brominated cobalt manganese acetate in solution with a weight ratio of Co/Mn/Br being in a predetermined ratio. When the brominated cobalt manganese acetate in solution meets a condition (Co×2.7)+(Mn×2.9)>Br, CoBr2, MnBr2, cobalt acetate and manganese acetate are used as sources for manufacturing; when the brominated cobalt manganese acetate in solution meets the condition (Co×2.7)+(Mn×2.9)<Br, CoBr2, MnBr2 and micro amount of bromine are used as sources for manufacturing without adding or with adding therein only with micro amount of HBr, corrosiveness of the oxidized catalyst is lowered.
