  • Patent number: 4798630
    Abstract: A method for chlorinating a clay mineral starting composition to produce reactive chloride intermediates, comprising: reacting said composition in substantially dry particulate form with gaseous SiCl.sub.4 to activate the surface of said composition, thereby forming said reactive chloride intermediate, said reaction being conducted at temperatures below that at which volatilization or dehydration of the starting composition will occur. The resulting compounds are highly reactive intermediates, which can then be functionalized by reaction with a large group of organics, or organic derivatives.

  • Patent number: 4798816
    Abstract: A process for treating a molecular sieve-containing alkylation catalyst to increase its selectivity for monoalkylation in which the alkylation catalyst is contacted with a feedstock comprising at least one organic compound under conditions such that a sufficient amount of carbonaceous material evenly deposits on the alkylation catalyst to substantially suppress its alkylation activity. The carbon-containing catalyst particles are then subjected to combustion by contacting them with a gaseous oxidizing agent at an elevated temperature to remove at least a portion of the carbonaceous material, preferably substantially all of the carbonaceous material, thereby increasing the selectivity of the catalyst for monoalkylation by at least about 1.0 percentage point. The resulting alkylation catalyst can be used to alkylate benzene and other aromatic compounds with ethylene, propylene or other olefins to produce high yields of ethylbenzene, cumene and other alkylated products.

    Abstract: The present invention relates to a method of purifying water for fish-breeding, according to which the water is optionally subjected to sedimentation, is subjected to sand filtration and to oxygenization, and to which the water also is subjected to a treatment with an ion exchanger mixture consisting of 40 to 70 percent clinoptilolite, 30 to 15 percent anion exchanger and 30 to 15 percent cation exchanger, the two latter being of cellulose type. The invention relates furthermore to the ion exchanger mixture mentioned.

  • Patent number: 4613491
    Abstract: There is disclosed a redistribution catalyst which is the reaction product of a quaternary ammonium halide salt or tertiary amine, and an inorganic carrier having surface hydroxyl groups, such as silica, zeolite, clays, and silicone resins. The catalyst is useful for the disproportionation of chlorosilicon hydrides to dichlorosilane and silane at reaction conditions including a temperature from 0.degree. to 200.degree. C., in liquid or vapor phase with a pressure from 0.1 to 10 atmospheres.

  • Patent number: 4594332
    Abstract: Hard, fracture-resistant catalysts are prepared from zeolites of the pentasil family by a process in which water, organic additives which increase the viscosity and a silicate are added to the zeolite powder, and the material is molded, dried and calcined.The fracture-resistant zeolites obtained are used as catalyst carriers.
