Abstract: A production process includes combining a first feed stream and a second feed stream to produce, in a pre-reforming reactor, a first product stream comprising CH4 and H2O; wherein the first feed stream contains a mixture of H2 and at least one selected from the group consisting of hydrocarbons having two or more carbon atoms and alcohols having two or more carbon atoms, and the mixture has a hydrogen stoichiometric ratio (?) of at least 0.1, and the second feed stream contains steam; feeding the first product stream into a reforming reactor; and reacting the first product stream in the reforming reactor to produce a second product stream containing CO and H2; and a catalyst for use in the process.

Yet further conversion of a synthetic crude to lubricants, diesel and the like, and/or the alcohols/DME to gasoline, olefins, and/or other oxygenates may also be included.

Abstract: A process for enhancing the activity of a catalyst metal particulate for hydrogenation reactions comprising calcining the particulate in an oxidant-containing atmosphere to partially oxidize it thereby forming a porous layer of oxides thereon, treating with an solution capable of oxidizing the calcined metal particulate and comprising a compound of a hydrogenation catalyst metal to where said metal particulate has absorbed a volume of solution equal to at least about 10% of its calculated pore volume and activating it by treatment with a hydrogen-containing gas at elevated temperatures thereby forming a dispersed active metal catalyst. Preferably, the treated particulate is calcined a second time under the same conditions as the first before final activation with a hydrogen-containing gas. The metal particulate is preferably sized after each calcination and any agglomerates larger than 250 microns are comminuted to a desired size.

Abstract: Dispersed Active Metal catalyst for hydrogenation reactions is produced by treating a substantially catalytically inactive metal particulate with a solution capable of oxidizing the metal particulate and comprising of at least one compound of a hydrogenation catalyst metal thereby forming a layer of at least one of hydroxides and oxides thereon. The metal particulate is activated by treatment with a hydrogen-containing gas at elevated temperatures to form a porous layer of Dispersed Active Metal catalyst. Preferably, the treated metal particulate is dried prior to activation, and also preferably calcined in an oxidant-containing atmosphere prior to activation. The treatment solution may advantageously contain a compound of at least one promoter metal for the added catalyst metal. The porosity of the layer provides enhanced catalyst activity as well as improved methane selectivity in the Fischer-Tropsch process.

Abstract: Cyanide and ammonia are removed from a gas, such as a synthesis gas, by catalytically hydrolyzing cyanide in the gas to ammonia, water scrubbing the hydrolyzed gas to dissolve ammonia and at least a portion of remaining cyanide, and optionally, contacting the scrubbed gas with an adsorbent for cyanide and ammonia to form a clean gas containing less than 50 vppb of a combined total of cyanide and ammonia. The clean synthesis gas is then fed into a hydrocarbon synthesis reactor wherein it produces hydrocarbons with substantially reduced catalyst deactivation and cleaner hydrocarbon products.

Abstract: Partially deactivated catalyst in a slurry hydrocarbon synthesis process is rejuvenated employing a cyclic rejuvenation process in which syngas or CO flow into the slurry is stopped to stop the hydrocarbon synthesis reaction, the CO purged out of the slurry with a purge gas in the presence of hydrogen, the catalyst rejuvenated with a hydrogen containing rejuvenating gas and the hydrocarbon synthesis reaction restarted by passing the synthesis gas feed back into the reactor. All or a portion of the purge gas and/or the rejuvenating gas may be recycled during the respective purge and/or rejuvenation. The hydrogen required during the purge is typically part of the purge gas.

Abstract: A reversibly deactivated, particulate catalyst in a slurry hydrocarbon synthesis slurry is rejuvenated by circulating the slurry from a slurry body through (i) a gas disengaging zone to remove gas bubbles from the slurry, (ii) a catalyst rejuvenation zone in which a catalyst rejuvenating gas contacts the catalyst in the slurry to rejuvenate it and form a rejuvenated catalyst slurry and, (iii) back into the slurry body. Removing at least a portion of the gas bubbles improves the rejuvenation process.

Abstract: Hydrogen containing tail gas from a hydrocarbon synthesis reactor is used as a hydrogen containing catalyst rejuvenating gas. If CO is present, the CO content, is less than 10 mole % of the gas and the H.sub.2 to CO mole ratio is greater than 3:1. At least a portion of the water and liquid hydrocarbons are removed from the tail gas, before it is used to rejuvenate the reversibly deactivated catalyst.
