    摘要: A process for methanation comprising a first region for flowing a stream over a solid oxide electrolysis cell. In this first region the stream consists of CO2, H2, and H2O, the stream is converted into a first conversion stream, and the solid oxide electrolysis cell is enhanced with a methanation catalyst. The process also has a removal region connected to the first region wherein the removal region is able to flow the first conversion stream away from the solid oxide electrolysis cell.

    摘要: Methods and systems relate to upgrading light olefins, such as ethylene, propylene and butylenes, diluted in a gas mixture, such as refinery fuel gas. The upgrading yields products in a gasoline, distillate, lube oil or wax range without requiring purification or compression of the gas mixture prior to feeding the gas mixture to a reactor. In operation, the mixture contacts a solid oligimerization catalyst, such as silica supported chromium, within the reactor. This contact occurs at a first temperature suitable to produce oligomers that are formed of the olefins and adsorb on the catalyst in liquid or solid phases. Next, heating the catalyst to a second temperature higher the first temperature desorbs the oligomers that are recovered and separated into the products.

    摘要: Methods for modifying a ZSM-5 zeolite by contacting the zeolite with an alkaline solution prior to combining with a binder material to produce a modified ZSM-5 catalyst extrudate that has substantially longer catalyst life, relative to an untreated ZSM-5 catalyst, for converting light olefins to products that may be used as a liquid transportation fuel blend stock. The alkaline solution is optionally sodium hydroxide. The binder is optionally alumina, bentonite or silica.
