    Abstract: A propensity to form gummy mixtures with water is a troublesome characteristic of a technical grade of boehmite, said power comprising a total ignition loss of about 25 percent, a volatile alcohol content corresponding to less than 1 percent carbon, minor amounts of amorphous alumina and a major amount of alpha mono hydrate. A portion of the technical boehmite is mildly calcined at 400*-500* C. for at least 15 minutes to provide a dehydrated alumina powder, which then mixed with a significantly larger amount of the uncalcined technical grade of boehmite, can be mixed with water for providing a plastic mixture suitable for shaping into catalyst particles. The catalyst particles are calcined above about 600* C. for more than 1 hour in the presence of steam to form attrition resistant particles of gamma alumina having the pore size distribution desirable in certain types of catalysts.

    Abstract: A process for preparing a catalyst comprising a metallic catalytic agent on a particulate carrier is disclosed which provides improved uniformity of distribution and fineness of division with narrowness of particle size distribution of the metallic catalytic agent on the carrier. The particles of carrier are suspended by agitation in an aqueous solution of a salt of the metallic catalytic agent and of a source, on heating in aqueous solution, of hydroxyl ions. The suspension is heated in a sealed vessel above 100* C to precipitate the metal or the particles with uniformity of distribution and fineness of division with narrowness of particle size distribution. The metal is converted by conventional procedures to the appropriate active, oxidized or reduced, state. The process is particularly significant with carriers, such as alumina and silica, that in alkaline media are liable to undergo structural charges.
