摘要： A new chromium-containing fluorination catalyst is described. The catalyst comprises an amount of zinc that promotes activity and from 0.1 to 8.0% by weight of the chromium in the catalyst based on the total weight of the chromium is present as chromium (VI). The use of the zinc-promoted, chromium-containing catalyst in a fluorination process in which a hydrocarbon or halogenated hydrocarbon is reacted with hydrogen fluoride in the vapour-phase at elevated temperatures is also described.

摘要： The present invention relates to a catalyst for synthesizing ethylenimine as well as a preparation method and application thereof. The related catalyst comprises a carrier and metal ions loaded on the carrier; the carrier is a composite oxide comprising titanium, silicon and phosphorus elements; the metal ions are magnesium ions, iron ions and cesium ions; the molar ratio of the magnesium ions to the iron ions to the cesium ions is (1-10):1:0.1; the mass of all metal ions is 0.5-10 percent of that of the carrier. In the related preparation method, a catalyst precursor is roasted at the temperature of 350-650° C., so that the catalyst is obtained; the catalyst precursor is the mixture of the carrier, soluble salt of magnesium, soluble salt of iron and soluble salt of cesium. The present invention also provides the application of the catalyst to synthesis of the ethylenimine by using amino alcohol as the raw material. Compared with a common catalyst which has the requirement on the temperature of over 400° C., the catalyst of the present invention obviously reduces the reaction temperature. The prepared catalyst can catalyze the intramolecular dehydration reaction of the amino alcohol and has relatively excellent selectivity.

摘要： Disclosed in the present invention is a chromium-free catalyst for gas-phase fluorination and an application thereof. The precursor of the related chromium-free catalyst for gas-phase fluorination consists of a compound containing iron element, a compound containing rare earth metal element and a compound containing element A, wherein element A is one selected from Ca, Al, Mg and Ti, the precursor is subjected to calcination and fluorination treatment to obtain the chromium-free catalyst for gas-phase fluorination. The precursor of the catalyst is calcined at 400-500° C. and fluorinated with hydrogen fluoride at 350-450° C. to obtain the chromium-free fluorinated catalyst. The catalyst has characteristics of being chromium-free and environment-friendly, good catalytic activity and long life etc. The catalyst can be used for preparing hydrofluoroolefins or hydrochlorofluoroolefins from halohydrocarbons.

摘要： Catalyst systems and methods for making and using the same. A method for making a catalyst support includes forming a mixture of a support material and a fluoride donor. The mixture is added to a fluidized bed reactor. The mixture is fluidized to form a fluidized bed while maintaining a ratio of a pressure drop across a distributor plate to a pressure drop across the fluidized bed of greater than about 7%. The mixture is calcined to decompose the fluoride donor, forming a fluorinated support.

摘要： Methods for making alpha olefin oligomers and polyalphaolefins include a step of contacting a C4 to C20 alpha olefin monomer and a catalyst system containing a metallocene, a first activator comprising a solid oxide chemically-treated with an electron withdrawing anion, and a second activator comprising an organoaluminum compound. The alpha olefin oligomers and polyalphaolefins prepared with these catalyst systems can have a high viscosity index combined with a low pour point, making them particularly useful in lubricant compositions and as viscosity modifiers.
