Abstract:
Stable carbonous catalyst particles composed of an inorganic catalytic metal/metal oxide powder and a carbonaceous binder material are formed having a basic inner substantially uniform-porous carbon coating of the catalytic powder, and may include an outer porous carbon coating layer. Suitable inorganic catalytic powders include zinc-chromite (ZnO/Cr03) and suitable carbonaceous liquid binders having molecular weight of 200-700 include partially polymerized furfuryl alcohol, which are mixed together, shaped and carbonized and partially oxidized at elevated temperature. Such stable carbonous catalyst particles such as 0. 020-0. 100 inch (0. 51-2. 54 mm) diameter extrudates, have total carbon content of 2-25 wt. % and improved crush strength of 1. 0-5 /mn, 50-300 m/g surface area, and can be advantageously utilized in fixed bed or ebullated/fluidized bed reactor operations.

Filed:
Mar 22, 2000
Appl. No.:
9/533000

C07C 400
C07C 400
US Classification:
208 85
Abstract:
A hydrocarbon liquid feedstock containing at least 50 wt. % chemically digested organic-MSW material is catalytically hydroconverted utilizing either a single stage or two-stage catalytic reaction process to produce desirable lower-boiling hydrocarbon liquid products. The catalyst can be either a particulate supported type catalyst such as containing cobalt and/or molybdenum and/or nickel on alumina support, or a dispersed slurry type catalyst containing mainly iron oxide with anions of molybdate, phosphate, sulfate or tungstate, and combinations thereof. Broad useful reaction conditions are 600-860. degree. F. (315-460. degree. C. ) temperature, 1000-3000 psi hydrogen partial pressure, and fresh feed rate of 20-60 pounds/hr/ft. sup. 3 reactor volume. Effluent material from the final stage catalytic reactor is phase separated and the resulting liquid portion is fractionated to produce the desired low-boiling hydrocarbon liquid products particularly useful as transportation fuels.

US Classification:
502 26
Abstract:
Spent catalysts removed from a catalytic hydrogenation process for hydrocarbon feedstocks, and containing carbon undesired metals contaminants deposits, are rejuvenated for reuse. Following solvent washing to remove process oils, the catalyst is treated either with chemicals which form sulfate or oxysulfate compounds with the metals contaminants, or with acids which remove the metal contaminants, such as 5-50 W % sulfuric acid in aqueous solution and 0-10 W % ammonium ion solutions to substantially remove the metals deposits. The acid treating occurs within the temperature range of 60. degree. -250. degree. F. for 5-120 minutes at substantially atmospheric pressure, after which the rejuvenated catalyst containing carbon deposits can be effectively reused in the catalytic hydrogenation process.

The catalyst materials are prepared by depositing a porous carbon layer on a support material of a selected metal oxide or compound to produce 5-40 wt. % carbon thereon, then preferentially treating the carbon based layer by partial oxidation, pyrolysis or reduction to enhance and activate the carbon layer on the catalyst. Promoter materials can also be advantageously added either to the support material or to the carbon layer in 0. 5-10 wt. % to provide an improved composite carbon-coated catalyst having total pore volume of 0. 3-1. 0 cc/gm, substantially increased surface area of 80-600 M. sup. 2 /gm, low surface acidity, particle strength of 1.

F. to produce lower boiling hydrocarbon liquid and gas products, wherein heavy RCR materials and metals compounds are removed in-situ from the reactor effluent liquid by solvent vapor extraction using a process-derived solvent vapor at supercritical conditions. In the process, the feedstock is catalytically hydroconverted at 780. degree. -860. degree. F. temperature, and the resulting liquid fraction is contacted with a process-derived solvent vapor fraction having a normal boiling range of 250. degree. -400. degree. F. and heated to supercritical temperature to dissolve and extract substantially all the hydrocarbon liquid fractions, and separate heavy RCR materials and the metals compounds contained therein. The resulting supercritical solvent vapor with dissolved liquid fraction is pressure-reduced and distilled to recover the needed solvent fraction and to provide a hydrocarbon liquid fraction product.

US Classification:
208407
Abstract:
A process for improving the upgrading/conversion of hydrocarbonaceous materials such as coals, petroleum residual oils, shale oils and tar sand bitumens. In the process, the free radicals formed from thermal cracking of the hydrocarbons are reacted with the free radicals formed by the thermal cracking of a free radical forming chemical reactant, such as dimethyl ether, to yield stable low molecular weight hydrocarbon distillate products. The hydrocarbonaceous feed material is preheated to a temperature of 600. degree. -700. degree. F. and the hydrocarbon and the free radicals forming chemical, such as dimethyl ether, are passed through a flow reactor at temperature of 750. degree. -900. degree. F. , pressure of 200-1000 psi, and liquid hourly space velocity of 0. 3 to 5. 0 LHSV. Free radicals formed from the hydrocarbon feed material and from the ether material react together in the reactor to produce low molecular weight hydrocarbon liquid materials.
