摘要： Catalyst structures and corresponding methods are described for the desulfurization of sulfur-containing light oil or model compounds under a specified gas atmosphere. The sulfur-containing feedstock is effectively converted while producing valuable hydrocarbon products such as BTX and carbon disulfide, as well as utilizing methane or natural gas resources, providing an economical and environmental innovation in the petroleum industry.

摘要： A de-hydrogenation catalyst and its use in dehydrogenation of hydrocarbons. The catalyst has low cracking activity and comprises gallium or gallium and platinum on an essentially non-acidic and amorphous alumina-phosphate or silica-alumina-phosphate support with an empirical chemical composition of [Al2O3][SiO2]Y[P2O5]Z, wherein Y is between 0 and 0.2 and Z is between 0.01 and 1.1, with a BET surface area above 50 m2/g, as measured by N2 adsorption experiment.

摘要： A process that catalytically converts olefinic (Alkenes, typically liquid at standard temperature and pressure) material in thermally cracked streams to meet olefin content specifications for crude oil transport pipelines. A thermally cracked stream or portion of a thermally cracked stream is selectively reacted to reduce the olefin content within a reactor operating at specific, controlled conditions in the presence of a catalyst and the absence of supplemental hydrogen. The process catalyst is comprised of a blend of select catalyzing metals supported on an alumina, silica or shape selective zeolite substrate together with appropriate pore acidic components.

摘要： Applying a sufficient quantity of an Alkali metal or an Alkaline earth metal to a fluid in a stripping process loop 106 to form a first intermediary compound and thereby, to strip the undesired element from the process fluid 102. The first intermediary compound 130 is processed in a recovery process loop 110 to recover the Alkali metal or Alkaline earth metal. The recovered Alkali metal or Alkaline earth metal is then re-introduced to an additional quantity of process fluid to strip and clean the undesired element from the additional quantity of the process fluid. A recovery process loop 110 may include either or both of a chemical substitution process, and an electrolytic process, effective to separate the Alkali metal or Alkaline earth metal from the undesired element or another compound.

摘要： A system for removing oxygenates from a hydrocarbon stream includes a caustic wash unit comprising a plurality of caustic wash loops, and a hydrogenation reactor. The hydrogenation reactor is configured to receive a first gaseous stream from a first caustic wash loop of the plurality of caustic wash loops and pass a second gaseous stream from the hydrogenation reactor to a second caustic wash loop of the plurality of caustic wash loops, wherein the hydrogenation reactor comprises a sulfided catalyst.

摘要： A method of removing oxygenates from a hydrocarbon stream comprises passing a hydrocarbon stream to a caustic tower having a plurality of loops, contacting the hydrocarbon stream with a sulfided catalyst between a first loop of the plurality of loops and a second loop of the plurality of loops to produce a reaction product, passing the reaction product to the second loop, removing at least a portion of the hydrogen sulfide in the second loop of the caustic tower to produce a product stream, and separating the product stream into a plurality of hydrocarbon streams in a separation zone located downstream of the caustic tower. The hydrocarbon stream comprises hydrocarbons, oxygen containing components, and sulfur containing compounds. At least a portion of the sulfur compounds react in the presence of the sulfided catalyst to produce hydrogen sulfide in the reaction product.

摘要： The process provided herein is concerned with disposal of oxidized sulfur compounds formed by oxidative desulfurization. The process uses solid base catalyst in the presence of a caustic solution or solid base catalyst pretreated with a base and eliminates the need to separate the sulfones from the hydrocarbon streams and recover the hydrocarbons.
