    摘要： A process for the production of hydrogen, including contacting a light paraffinic hydrocarbon such as ethane, propane, n-butane, iso-butane, n-pentane, iso-pentane, etc., with a catalyst comprising an active metal selected from the group consisting of a Group VIII metal, such as platinum, rhodium, ruthenium, palladium, and nickel, and a Group VIB metal, such as chromium, molybdenum and tungsten, in an amount between about 0.5 and 15% by weight of the finished catalyst and a promoter selected from the group consisting of Group I, Group II, Rare Earth, and Group IVA metals of the Periodic System and mixtures thereof, in an amount between about 1 and 15% by weight based on the finished catalyst, both deposited on an inert oxide carrier; liquefying the effluent product, as by condensation or compression; flashing the dry gas portion containing hydrogen therefrom; if desired, further purifying the hydrogen by cryogenic, adsorption and diffusion methods, etc.; separating an unsaturated portion from a saturated portion of the remaining product, as by distillation, adsorption, solvent extraction, selective polymerization, selective aromatic alkylation, selective paraffin alkylation, etc., and recycling unreacted paraffins to the contacting step. The hydrogen recovered from the flashing step is also utilized for the hydrogenation of heavy unsaturated hydrocarbon materials, such as coal liquids, by contacting the heavy liquids with the hydrogen in the presence of a hydrogenation catalyst, preferably of the same character as the hydrogen-producing catalyst, and under conditions sufficient to hydrogenate the heavy liquids.

    摘要： A process for economically converting carbo-metallic oils to lighter products. The carbo-metallic oils contain 650.degree. F.+ material which is characterized by containing material which will not boil below about 1025.degree. F., a carbon residue on pyrolysis of at least about 2, and a nickel plus vanadium content of at least about 4 parts per million. This process comprises adding an additive to the feedstock consisting of a compound containing titanium, zirconium, or aluminum so as to restore cracking activity of high metal contaminated and deactivated, zeolite containing catalysts, resulting from processing of these carbo-metallic oils.

    摘要： A process is disclosed for economically converting carbo-metallic oils to liquid fuel products by bringing a converter feed containing 650.degree. F.+ material characterized by a carbon residue on pyrolysis of at least about 1 and by containing at least about 4 ppm of Nickel Equivalents of heavy metals, including nickel, into contact with a particulate cracking catalyst in a progressive flow type reactor having an elongated conversion zone. The suspension of catalyst and feed in the reactor has a vapor residence time in the range of about 0.5 to about 10 seconds, a temperature of about 900.degree. F. to about 1400.degree. F. and a pressure of about 10 to about 50 pounds per square inch absolute for causing a conversion per pass in the range of about 50 to about 90 percent while depositing nickel on the catalyst and coke on the catalyst in amounts in the range of about 0.3 to about 3 percent by weight. The coke-laden catalyst is separated from the resulting stream of hydrocarbons and regenerated by combustion of the coke with oxygen, the regenerated catalyst being characterized by deposited nickel in at least a partially oxidized state and a level of carbon on catalyst of about 0.25 percent by weight or less. The regenerated catalyst is contacted with a reducing gas under reducing conditions sufficient to reduce at least a portion of the oxidized nickel deposits to a reduced state and the regenerated catalyst with reduced nickel deposits is recycled to the conversion zone for contact with fresh feed. Water is also introduced into the reactor conversion zone and the amount of water and the amount of reduced nickel on the recycled catalyst are sufficient to provide a steam reforming reaction so that hydrogen deficient components of the feed are converted to products having higher hydrogen to carbon ratios and the amount of feed converted to coke is reduced. The amount of deposited nickel on catalyst is preferably in the range from about 2,000 to about 20,000 ppm and the mole ratio of water relative to feed in the conversion zone is preferably in the range from about 2 to about 14.

    摘要： Hydrocarbon fractions boiling between 180.degree. and 600.degree.F. and containing aromatics, olefins, and sulfur and nitrogen compounds are hydrogenated with a platinum-palladium catalyst to reduce the concentration of aromatics and olefins. The catalyst is prepared by saturating a porous inert carrier, preferably alumina, with an aqueous acid solution of chloroplatinic acid and palladium (ous) chloride in a specified mole ratio of platinum to palladium. The saturated carrier is subsequently dried, calcined and reduced.
