A catalyst nominally containing zeolite, clay and silica-alumina gel. The zeolite is preferably partially exchanged with high La/Ce ratio solution in a wetting step. The catayst and processes for its manufacture and use are disclosed. The catalyst is excellent for processing heavy oils, generally produces higher LCO/slurry oil ratio and has high metals tolerance.

Carbometallic oil conversion with zeolite y containing catalyst

A catalyst nominally containing zeolite, preferably HY zeolite and/or ultrastable HY zeolite, clay, alumina and an acidic silica-alumina co-gel matrix. The zeolite is preferably partially exchanged with high La/Ce ratio solution in a wetting step, and rare earths are precipitated onto the matrix. The catalyst has high metals tolerance and is capable of cracking heavy reduced crude oils, producing higher LCO/slurry oil ratio.

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.

Hydrogen production

A process for disproportionating a paraffinic hydrocarbon containing 2 to 6 carbon atoms to produce paraffinic hydrocarbons containing one more and one less carbon fragment per molecule is disclosed. In the process the paraffinic hydrocarbon is contacted at about 400.degree. to 1000.degree.F. with an acidic, crystalline aluminosilicate catalyst having a pore size of about 8 to 15 A, silica to alumina mole ratio greater than 2 to 1 and at least about 0.4 equivalent per gram atom of aluminum of hydrogen or metal ion.
