摘要:The present invention shows a synthesis method for a highly dispersed supported catalyst over a KIT-6 type nanostructured mesoporous oxide with elements from Groups IIIA or IVA, or IVB. The method includes the synthesis of the support, the incorporation of CoMo and NiMo active phases through impregnation to pore volume, assisted by ultrasound, calcination at controlled conditions in order to obtain a phase of hydrated trioxide molybdenum or molybdic acid, which facilitates the subsequent sulfihydration and the mechanical mixing of a CoMoS/support with a hydrodenitrogenant NiMoS/support additive. The obtained catalysts exhibit a catalytic activity mainly in reactions of hydrotreatment, hydrodesulfurization, and hydrodenitrogenation.

摘要:The present invention relates to a process for hydrocyanating a hydrocarbon-based compound containing at least one ethylenic unsaturation by reaction in liquid medium with hydrogen cyanide in the presence of a catalyst comprising a metal element chosen from transition metals and an organophosphorus ligand, characterized in that the organophosphorus ligand is a monodentate organophosphorus compound. The present invention is in particular useful for the synthesis of adiponitrile from butadiene.

摘要:This invention is directed to a synthesis process for preparing magnesium aluminosilicate clays and to the products of said process. Briefly, a silicon component, an aluminum component, and a magnesium component are combined, under aqueous conditions and at an acidic pH, to form a first reaction mixture and subsequently the pH of the first reaction mixture is adjusted to greater than 7.5 to form a second reaction mixture. The second reaction mixture is allowed to react under conditions sufficient to form the magnesium aluminosilicate clay of the present invention. The invention is also directed to catalyst compositions comprising the magnesium aluminosilicate clays synthesized according to the process of the invention. The resulting magnesium aluminosilicate clay can be used as a catalyst or as a component in catalyst compositions. The invention is further directed to a magnesium aluminosilicate clay with a characteristic 29 Si NMR spectrum and the use of said magnesium aluminosilicate clay in catalyst compositions.

摘要:The present invention discloses a high compact density nickel-cobalt-manganese multi-element lithium ion battery cathode material with dopants and methods of its preparation. A preparation method of this battery cathode material is as follows: (A) preparing a nickel-cobalt-manganese multi-element intermediate with dopants by co-precipitation or chemical synthesis; (B) preparing a mixture by mixing said multi-element intermediate with a lithium salt; (C) pre-treating the said mixture, then adding into it polyvinyl alcohol and mixing uniformly; (D) pressing the resulting material into lumps, calcining the lumps at 800Ëœ950° C., cooling after its removal from the furnace, crushing, passing through a 400 mesh sieve; (E) calcining the resulting power at 700Ëœ800° C., cooling after its removal from the furnace, crushing and sieving to obtain a product. The lithium battery cathode material obtained using the above-described method has the formula LiNi x Co y Mn z M (1-x-y-z) O 2 . The cathode material has non-agglomerated single crystal particles. The material has a particle size ranging from 0.6Ëœ30 μm, a compact density of 3.5Ëœ3.7 g/cm 3 , and an initial discharge capacity of 150Ëœ165 mAh/g, with excellent cycling and safety performance.
