  • Method of preparing a hydrogen-permeable membrane catalyst on a base of palladium or its alloys for the hydrogenation of unsaturated organic compounds
    Patent number: 4132668
    Abstract: The invention is related to a method of preparing a hydrogen-permeable membrane catalyst on a base of palladium or its alloys for the hydrogenation of unsaturated organic compounds.According to the invention the surface of a metalloceramic sheet on a base of nickel, copper or stainless steel with a thickness from 0.05 to 1 mm is covered with an organosilicon polymer which is subsequently cured at a temperature ranging from 20 to 150.degree. C.The curing results in the formation of a film of the organosilicon polymer with a thickness from 0.01 to 1 mm, whereupon a layer of palladium or its alloy with a thickness from 0.001 to 0.1 micron is deposited on the polymer film.The method of the invention allows decreasing by hundreds of times the consumption of palladium, and other noble metals such as ruthenium, rhodium, rhenium, silver, and gold.
