Abstract: The invention concerns a supported catalyst in the form of packing and constructed on an open-pore support material on whose external and internal surfaces a macro-porous ion exchange resin is mechanically and/or chemically affixed.

Abstract: Metal oxide powders comprised of Cr(III) oxide, Ti(IV) oxide, V(V) oxide, or mixtures of these, or metal mixed oxides comprised of Cr(III) oxide and Ti(IV) oxide and V(V) oxide, or their mixtures. They have BET surfaces of 5-50m.sup.2 /g and mean particle diameters of 25-350 nm and are useful to increase conversion and selectivity in the manufacture of mono-olefins by catalytic dehydrogenation of saturated hydrocarbons. The metal oxide powders are produced from mixtures of the vaporized metal compounds chromyl chloride, titanium tetrachloride, and vanadyl chloride, in the presence of certain gases by laser pyrolysis.

Abstract: Atomic hydrogen for chemical reaction is produced in relatively high concentrations by the combustion of molecular hydrogen with a substoichiometric quantity of oxygen. The chemical reactant is supplied at the point of the development of the atomic hydrogen. Combustion is effected at pressures between 10 mbar and 1.5 bar, with a mole ratio of molecular hydrogen to molecular oxygen of 2.3 to 5.0.

Abstract: A motor fuel comprising 35-98% hydrocarbon-containing base and 2-65% by volume of an additive which comprises a mixture containing(a) 5-35% by volume of methyl tert-butyl ether;(b) 5-40% by volume of isopropyl tert-butyl ether; and(c) 5-40% by volume of sec-butyl tert-butyl ether,has a high octane number and reduces exhaust pollutants.

Abstract: A process for producing isopropyl alcohol and isopropyl tert-butyl ether from a mixture of light hydrocarbons containing propane and butane, comprises:(a) separating from the mixture of light hydrocarbons a propane fraction and a butane fraction containing at least n-butane;(b) isomerizing at least a portion of the n-butane in the butane fraction from step (a) whereby a hydrocarbon mixture containing at least n-butane and isobutane is formed;(c) catalytically dehydrogenating the isobutane in the hydrocarbon mixture from step (b) whereby a hydrocarbon mixture containing at least isobutene is produced;(d) catalytically dehydrogenating the propane in the propane fraction from step (a) whereby a hydrocarbon mixture containing at least propene is produced;(e) reacting the propene in the hydrocarbon mixture from step (d) with water, whereby a mixture containing hydrocarbons and isopropyl alcohol is formed;(f) reacting the isopropyl alcohol from step (e) with at least part of the isobutene in the hydrocarbon mixture
