摘要: The hydrogenation of olefin polymers and especially diene polymers can be carried out effectively in a fixed bed mode of operation, preferably with up-flow of polymer solution, using a heterogeneous catalyst containing an active hydrogenation metal in which the catalyst support has defined surface area and pore volume characteristics and the hydrogenation metal or metal compound is incorporated into the support by impregnation with a non-aqueous solution of the metal or metal compound.

摘要: A process for preparing silica-alumina compositions comprises mixing a first aqueous solution containing an aluminum salt (preferably KAl(SO.sub.4).sub.2) and an ammonium salt (preferably (NH.sub.4).sub.2 SO.sub.4) with a second solution containing an alkali metal silicate (preferably Na.sub.2 SiO.sub.3), wherein the mol ratio of the alkali metal silicate to the aluminum salt is in the range of from about 2:1 to about 20:1, and the concentration of the ammonium salt is chosen so as to afford coprecipitation of silica-alumina hydrogel (preferably at a pH of about 3-6). The thus coprecipitated silica-alumina hydrogel can be separated from the mixture of the two solutions, optionally washed, and calcined so as to prepare acidic silica-alumina suitable as cracking catalyst material.
