摘要: The removal of ethylene from gases which contain the ethylene in a concentration of not more than 1.8% by volume by means of a supported palladium catalyst which contains from 0.05 to 10 g of palladium per liter of an inert inorganic carrier, the oxidation reaction being started at a temperature of from 180.degree. to 200.degree. C.

摘要: Spherical refining catalysts containing cobalt and/or nickel together with molybdenum on aluminum oxide are prepared in closed mixers provided with mixing elements from spray-dried powders such as catalyst preparations or carriers using peptizing agents. The catalysts thus prepared have a bulk density much higher than that of extrudates of similar composition. Their surface and pore size distribution make them suitable for use in the catalytic refining of hydrocarbon fractions containing metal and asphalt, and particularly for refining vacuum distillates and residues from atmospheric distillation.
