    Abstract: A method for preparing an olefin oxidation catalyst, which comprises impregnating silver oxide or a water-insoluble silver salt, e.g. silver carbonate, silver carboxylates (having from 1 to 10 carbon atoms), silver chloride, etc., having a surface area of from 20 to 40 m2/g, preferably from 25 to 35 m2/g, with a solution containing a decomposable salt, selected from the group consisting of salts of Groups VII-B, I-B, or the iron group of Group VIII of the Periodic Table of the Elements, drying said impregnated salt, and activating by contacting with a reducing environment. Preferably the silver compound is silver oxide and said decomposable salt is selected from the group consisting of gold, copper, rhenium, manganese, and iron salts. The catalysts prepared by the instant method are especially effective in the oxidation of ethylene to ethylene oxide.

    Abstract: A process is taught for producing a ruthenium catalyst. A fixing compound, selected from alkaline earth materials or rare earth materials which decompose to an oxide of the material, is deposited on a catalytic support. A hydrated, halogenated ruthenium compound which reduces to ruthenium is also deposited on the catalytic support. The materials on the support are heated in a reducing atmosphere to form the ruthenium metal. After the reducing step the materials are fixed by heating them to a ruthenate forming temperature. The product produced in this manner is desirable for use in the catalytic conversion, in a reducing atmosphere, of oxides of nitrogen. The ruthenium catalyst of the product produced by this method is resistant to volatilization when exposed to an oxidizing ambient.

    Abstract: A catalytic reforming process wherein naphtha feed streams, boiling from about 80* to 450* F, and comprising naphthenes, paraffins and aromatics, are contacted, in an initial reaction zone, with a hydrogen containing gas, in the presence of a catalyst comprising Pt and a group IB metal supported on a refractory oxide; passed into a tail zone wherein the feed stream is again contacted with a catalyst and thereby further reacted; and a high octane product is recovered. In a preferred embodiment the Group IB metal is Cu.

    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.
