Publication number: 20090321321Abstract: The invention provides an adsorbent for removing sulfur from cracking gasoline or diesel fuel, which adsorbent comprises: (1) a carrier consisting of a source of silica, an inorganic oxide binder, and at least one oxide of metal selected from Groups IIB, VB and VIB; (2) at least one accelerant metal which is capable of reducing the sulfur in oxidized state to hydrogen sulfide and has a ?<0.5, wherein ?=(the amount in percentage of accelerant metal in crystal phase)/(the amount in percentage of accelerant metal in the adsorbent). The active components in the adsorbent can be evenly dispersed on the carrier in a matter close to monolayer dispersion, and which greatly improves the activity of the adsorbent. The preparation method and the use of the above adsorbent are provided.Type: ApplicationFiled: June 30, 2009Publication date: December 31, 2009Applicants: China Petroleum & Chemical Corporation, Research Institute of Petroleum Processing, SinopecInventors: Jun Long, Huiping Tian, Wei Lin

Publication number: 20090308792Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.Type: ApplicationFiled: June 17, 2008Publication date: December 17, 2009Applicant: HEADWATERS TECHNOLOGY INNOVATION, LLCInventors: Zhihua Wu, Zhenhua Zhou, Bing Zhou

Publication number: 20090283448Abstract: A hydrocarbon desulfurization system that circulates fluidizable solid particles through a fluidized bed reactor, a fluidized bed regenerator, and a fluidized bed reducer to thereby provide for substantially continuous desulfurization of a hydrocarbon-containing fluid stream and substantially continuous regeneration of the solid particles. A novel transport system is employed for transporting the solid particles between the reactor, the regenerator, and the reducer. The transport system uses close-coupled vessels and gravity flow between various vessels to minimize equipment cost and particle attrition.Type: ApplicationFiled: October 2, 2006Publication date: November 19, 2009Applicant: ConocoPhillips CompanyInventors: Victor G.
