  • Patent number: 4116870
    Abstract: A catalyst useful for the hydrotreatment of hydrocarbons comprising, on a refractory inorganic oxide support, the following metals:(a) from 0.02 to 2% of at least one platinum metal;(b) from 0.02 to 2% of at least one metal belonging to the group consisting of zirconium, titanium, and tungsten;(c) from 0.02 to 2% tin.This catalyst is preferably halogenated, typically with chlorine, from 0.4 to 2%.Catalysts according to this invention are particularly useful for isomerization of a charge of alkylaromatic hydrocarbons, and particularly those having eight carbon atoms. The preferred isomerization catalyst is a platinum, tin and zirconium trimetallic catalyst halogenated with chlorine approximately from 1 to 2% based on the total catalyst weight.Said catalysts are also useful for hydroreforming and aromatizing being surprisingly superior for all these types of reactions.

  • Patent number: 4071437
    Abstract: Catalysts are disclosed for the hydrotreatment of hydrocarbons, and particularly for reforming, which contain no platinum and which consist of:A refractory-mineral carrier (alumina).0.05 to 5 wt. % of at least one first metal from the group consisting of iron, cobalt, and nickel.At least one second metal from the group consisting of tin (0.01 to 5%), lead (0.01 to 10%), and germanium (0.01 to 4%).Possibly from 0.01 to 0.5% of sulfur.Processes for preparation of these catalysts, by impregnation, and for their use are disclosed. It is preferable to deposit the metal (or the metals) from the tin-germanium-lead group before the metal or metals from the iron-cobalt-nickel group are deposited.

  • Patent number: 4039477
    Abstract: Catalysts particularly useful for hydroreforming and isomerization of hydrocarbons formed of a refractory mineral oxide carrier having a halogen in combined form and the following metals in free or combined state:A. A metal from the platinum group (0.02 to 2%);B. tin (0.02 to 2%); andC. at least one metal selected from the group of scandium, yttrium, thorium, uranium, and the rare earths metals (0.01 to 5%) -- said percentages being based upon the total weight of the catalyst, said catalyst preferably having platinum and chlorine. Also the use of said catalyst in the aforementioned hydrotreatments.

  • Patent number: 4002687
    Abstract: Process, and resulting product, for improved hydroperoxidation of branched alkanes of at least 4 carbon atoms, especially useful in preparation of isoprene from isopentane; comprising the substantial elimination of acetic acid and similar by-products in the hydroperoxidation reaction which are harmful to the yield of the desired hydroperoxides; all of which is achieved by at least one washing between at least two successive oxidizing reactors. The wash solution may be just water or advantageously a pre-saturated aqueous solution containing the oxidation products which are desired not to be extracted from the organic phase of the reaction medium.

  • Patent number: 3957900
    Abstract: Method for dehydrating diols into diolefins and/or olefin alcohols by contacting said diols under dehydration conditions with a catalyst prepared by forming an intimate mixture of finely divided solid particles of at least one pyrophosphate and at least one acid orthophosphate of at least one metal belonging to the group consisting of lithium, sodium, strontium, and barium into a formed mass which is thereafter calcined to transform the acid orthophosphate into pyrophosphate.
