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: A process of making an aromatization catalyst comprising: (a) mixing a zeolite, a binder, and water to form a mixture; (b) extruding the mixture to form a green extrudate; (c) drying the green extrudate to form a dried green extrudate; (d) calcining the dried green extrudate to form a support, wherein calcining the dried green extrudate is the only calcination step in the process; (e) washing the support to form a washed support; (f) drying the washed support to form a dried washed support; (g) impregnating the dried washed support with a Group 8-10 transition metal compound and at least one halide-containing compound to form a metalized-halided material; and (h) vacuum drying the metalized-halided material to form a dried metalized-halided material which is the aromatization catalyst.

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: The present application provides a method for preparing lanthanide fluoride two-dimensional porous nanosheets and belongs to the field of novel materials. In the present application, mixing a water-soluble lanthanide metal salt and an aqueous solution of sodium acetate in a nitrogen atmosphere to obtain a mixed solution, and adding an aqueous solution of fluorine-containing salt to the mixed solution obtained for precipitation reaction to produce lanthanide fluoride two-dimensional porous nanosheets. In the preparation process provided by the present application, no additional surfactant or template agent needs to be added, the pollution of the surfactant to the surface of the prepared material is avoided and the tedious after-treatment steps to template agent are reduced. Accordingly, the large-scale production can be realized, and the lanthanide fluoride two-dimensional porous nanosheets constructed by nanoparticles are prepared in large scale by one step. Moreover, no other organic solvents are required, and the pollution to the environment during the preparation process is avoided.
