Abstract: Hydroconversion of hydrocarbons, particularly reforming of naphthas, is conducted in the presence of hydrogen with a catalyst comprising technetium in association with a porous solid carrier. Preferably the catalyst contains a platinum group component in addition to technetium.

Abstract: Gasoline synthesized from carbon monoxide and hydrogen is contacted with a solid phosphoric acid catalyst to improve the octane number of the gasoline.

Abstract: Apparatus and method for removing particulate impurities from a fluid stream flowing into a bed of discrete solid elements, such as a bed of catalyst particles. An improved basket design is provided which maximizes the use of the bed and the mesh area of the basket to remove the particulate impurities in such a manner that the cycle life of the bed of catalyst particles or the like is extended.

Abstract: A system for controlling the hydrogen/hydrocarbon mole ratio in a continuous hydrocarbon conversion process wherein the hydrocarbonaceous feed stock is catalytically reacted in a hydrogen atmosphere. Applicable to both hydrogen-consuming and hydrogen-producing processes, in which the reaction zone effluent is separated to provide a liquid product phase and a hydrogen-rich vaporous phase, a portion of the latter being recycled to the catalytic reaction zone, the control system affords improved overall operation of the particular process in addition to increased catalyst activity and stability. Analyzers are utilized to monitor composition characteristics of the charge stock and liquid product, and the hydrogen concentration of the vaporous phase recycled to the reaction zone.

Abstract: A method of producing a catalyst comprising impregnating shaped carriers of refractory material (e.g., alumina) with a solution of the salts of an active metal constituent (e.g., nickel) and an acidic or amphoteric constituent (e.g., uranium), the shaped carriers being fired to decompose the salts to form the oxide of the metal constituent and a compound or solid solution of the oxides of an active metal and acidic or amphoteric constituents, the active components of the catalyst being formed by reduction of the said oxides and/or compound or solid solution in a reducing atmosphere to form the active metal and the acidic or amphoteric constituent in a reduced or unreduced state, the shaped carriers then being impregnated with a water soluble compound of alkali or alkaline earth metal (e.g. barium hydroxide) and finally fixed as the carbonate by heating in an atmosphere containing CO.sub.2.

Abstract: A gasoline fraction is catalytically reformed by contacting the gasoline fraction and a hydrogen stream at reforming conditions with an activated bimetallic acidic catalytic composite comprising a combination of a platinum group component, a tin component and a halogen component with a porous carrier material, the catalytic composite having been activated by contacting same with an activating gas comprising oxygen and a halogenating component selected from the group consisting of halogen and hydrogen halide at a temperature between 700.degree. and 1100.degree. F. for a time of at least 0.5 to about 10 hours.

Abstract: Hydroconversion of hydrocarbons, particularly reforming of naphthas, is conducted in the presence of hydrogen with a catalyst comprising technetium in association with a porous solid carrier. Preferably the catalyst contains a platinum group component in addition to technetium.

Abstract: Acyclic and alicyclic aliphatic hydrocarbons are isomerized by contacting the same with hydrogen in the presence of a difficultly reduceable metal halide in combination with at least a molar equivalent of hydrogen halide. The preferred catalyst system is tantalum pentafluoride, niobium pentafluoride or their mixtures in combination with at least a five-fold molar excess of hydrogen fluoride.
