Abstract
A catalyst containing not more than 5 per cent by weight of a metallic mixture of 60 to 99 parts by weight of palladium and 40 to 1 part of copper, silver, or gold disposed on a catalytically inactive carrier such as pumice, inactive alumina, diatomaceous earth, asbestos, coke or charcoal, is used in the selective hydrogenation of acetylene in the presence of ethylene (see Group IV (b)). The catalysts are prepared by treating the support with aqueous solutions of soluble salts of the metals which salts can be decomposed at temperatures below 500 DEG C., drying the mixture, roasting in air at 325-500 DEG C. to convert the metal salts to the oxides and reducing to the metal in hydrogen at 25-450 DEG C. Specified salts are palladium nitrate, cupric nitrate, silver nitrate and chlorocuric acid. The catalysts are gradually inactivated by the deposition of carbonaceous matter and are readily reactivated by burning off the deposits by oxidation at, e.g., 400 DEG C., followed by reduction of the catalyst in hydrogen.ALSO:Acetylene is selectively hydrogenated in the presence of ethylene by contacting the mixture together with more than one mol. of hydrogen per mol. of acetylene with a catalyst containing a metallic mixture containing 60 to 99 parts by weight of palladium and 40 to 1 part of copper, silver or gold (see Group III). The feed is preferably desulphurized, e.g. by passing through basic lead acetate. Temperatures of room temperature to 250 DEG C. are used at above, below or at atmospheric pressure. A typical example illustrates the hydrogenation of acetylene in a gas stream produced from a commercial gas cracking plant consisting mostly of ethylene with small amounts of acetylene (3-4 volume per cent) methane, carbon dioxide and air. Hydrogen is added and the gas passed over a catalyst containing 0.2 per cent palladium and 0.01 per cent silver on diatomaceous earth at 100 DEG C. and 50 p.s.i.g.; the product stream is free of acetylene.
