Abstract: A process for liquefying coal by subjecting bituminous coal particles to electromagnetic wave energy and having wavelengths of from about 0.001 to about 100 A and recovering valuable liquid hydrocarbon products from the resulting liquid coal extract.

Abstract: A nonacidic multimetallic catalytic composite especially useful for the conversion of hydrocarbons comprises a combination of catalytically effective amounts of a platinum group component, a cobalt component, a uranium component and an alkali or alkaline earth component with a porous carrier material. A specific example of the nonacidic catalytic composite disclosed herein is a composite containing about 0.01 to about 2 wt. % platinum group metal, about 0.05 to about 5 wt. % cobalt, about 0.1 to about 10 wt. % uranium and about 0.1 to about 5 wt. % alkali metal or alkaline earth metal.

Abstract: An acidic multimetallic catalytic composite especially useful for converting hydrocarbons comprises a combination of catalytically effective amounts of a platinum group component, a nickel component, a uranium component, and a halogen component with a porous carrier material. The platinum group, uranium, nickel, and halogen components are present in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum group metal, about 0.1 to about 10 wt. % uranium, about 0.05 to about 5 wt. % nickel, and about 0.1 to about 3.5 wt. % halogen.

Abstract: Dehydrogenatable hydrocarbons are dehydrogenated by contacting them, at dehydrogenation conditions, with a catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a cobalt component, and a uranium component with a porous carrier material. A specific example of the nonacidic catalytic composite disclosed herein is a combination of a platinum group component, a cobalt component, a uranium component, and an alkali or alkaline earth component with a porous carrier material in amounts sufficient to result in a composite containing about 0.01 to about 2 wt. % platinum group metal, about 0.05 to about 5 wt. % cobalt, about 0.1 to about 10 wt. % uranium and about 0.1 to about 5 wt. % alkali metal or alkaline earth metal.

Abstract: Dehydrocyclizable hydrocarbons are converted to aromatics by contacting them at dehydrocyclization conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a cobalt component, a uranium component, and a halogen component with a porous carrier material. The platinum group, cobalt, uranium and halogen components are present in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum group metal, about 0.05 to about 5 wt. % cobalt, about 0.1 to about 10 wt. % uranium, and about 0.1 to about 3.5 wt. % halogen.
