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： Oligomer products are produced by reacting an alpha olefin and a vinylidene compound in the presence of a solid catalyst, such as a solid oxide or a chemically-treated solid oxide. Metallocene compounds, organoaluminum compounds, and BF3 are not needed to perform the reaction. Oligomer products formed by processes disclosed herein have a trimer:tetramer weight ratio of at least 2:1.

摘要： Disclosed is a method for reducing carbon deposits on a catalyst in recycling HFC-23. The recycling is realized by means of a fluorine-chlorine exchange reaction with HFC-23 and a halogenated hydrocarbon. The catalyst for the fluorine-chlorine exchange reaction comprises a main body catalyst and a precious metal. The precious metal is selected from at least one of Pt, Pd, Ru, Au or Rh, and has an addition amount of 0.01-2 wt %. During the fluorine-chlorine exchange reaction, hydrogen gas is introduced. The invention has advantages of good catalyst stability, long life, etc.

摘要： Methods for producing supported catalysts containing a transition metal and a bound zeolite base are disclosed. These methods employ a step of washing the bound zeolite base in the presence of an alkali metal, prior to impregnating the bound zeolitic support with the transition metal. Alkali metals such as potassium and cesium may be used.

摘要： Disclosed herein are catalyst compositions containing a heteroatomic ligand transition metal compound complex, a chemically-treated solid oxide, and an organoaluminum compound. These catalyst compositions can be used in an ethylene oligomerization process to produce a liquid oligomer product containing hexene and octene, as well as a solid polymer product with a molecular weight sufficiently high to permit easy separation of the liquid oligomer product from the solid polymer product.

摘要： Disclosed in the present invention are a chromium-free gas phase fluorination catalyst and an application thereof. The precursor of the related chromium-free gas phase fluorination catalyst 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 roasting and fluorination treating to obtain the chromium-free gas phase fluorination catalyst. The precursor of the catalyst is roasted at 400-500° C. and fluoridized with hydrogen fluoride at 350-450° C. to obtain the chromium-free gas phase fluorination 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.
