    Abstract: Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum or palladium component, a rhodium component, a rhenium component, a tin component, and a halogen component with a porous carrier material. The platinum or palladium component, rhodium component, rhenium component, tin component, and halogen component are present in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum or palladium metal, about 0.01 to about 2 wt. % rhodium, about 0.01 to about 2 wt. % rhenium, about 0.01 to about 5 wt. % tin, and about 0.1 to about 3.5 wt. % halogen. Moreover, these metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum or palladium component is present therein in the elemental metallic state, substantially all of the rhenium and rhodium components are present therein in the elemental metallic state or in a state which is reducible to the elemental metallic state under hydrocarbon conversion conditions or in a mixture of these states and substantially all of the tin component is present in an oxidation state above that of the elemental metal and in a particle size which is less than 100 Angstroms in maximum dimension. A specific example of the type of hydrocarbon conversion process disclosed is a process for the catalytic reforming of a low-octane gasoline fraction wherein the gasoline fraction and a hydrogen stream are contacted with the acidic multimetallic catalyst disclosed herein at reforming conditions.

    Abstract: High surface area alumina bodies for use as catalysts, catalyst carriers, and sorbents are made by controlled mixing of fine particle size platy boehmite alumina aggregates with a monobasic acid to produce non-pasty free-flowing particulate mass of aggregates of boehmite. This mass can then be formed by pressure into selected shapes such as rings, saddles, cylinders, solid, or hollow, or pellets, dried and fired to produce bodies of boehmite, gamma alumina, delta alumina, theta alumina or alpha alumina ranging in surface area of from 10 square meters per gram to greater than 300 square meters per gram. Catalytic metal can be included in the bodies by impregnation, before or after firing, or can be incorporated by inclusion in the aqueous acid treating solution.

    Abstract: A bithermal, catalytic, hydrogen isotope exchange process between liquid water and hydrogen gas to effect concentration of the deuterium isotope of hydrogen, wherein liquid water and hydrogen gas are contacted with one another and with at least one catalytically active metal selected from Group VIII of the Periodic Table, the catalyst body has a water repellent, gas and water vapour permeable, organic polymer or resin coating, preferably a fluorinated olefin polymer or silicone resin coating, so that the isotope exchange takes place by two simultaneously occurring, and closely coupled in space, steps namely, using protium (H) and deuterium (D) as the example, HD gas + H2O vapour catalyst H2 gas + HDO vapour
