Patent number: 8920635Abstract: Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organo sulfur compounds.Type: GrantFiled: January 14, 2013Date of Patent: December 30, 2014Assignees: Saudi Arabian Oil Company, Boreskov Instutite of CatalysisInventors: Abdennour Bourane, Omer Refa Koseoglu, Zinfer Ismagilov, Svetlana Yashnik, Mikhail Kerzhentsev, Valentin Parmon

Patent number: 8906227Abstract: Desulfurization of hydrocarbon feeds is achieved by first contacting the entire feed with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions; a flashing column downstream of the hydrodesulfurization reaction zone fractionates the effluent to obtain a first fraction which contains refractory organosulfur compounds and a second fraction that is substantially free of organosulfur compounds, since the organosulfur compounds boiling in the range of this fraction were the labile organosulfur compounds which were initially removed by mild hydrodesulfurization. The first fraction is contacted with a gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organosulfur compounds.Type: GrantFiled: January 15, 2013Date of Patent: December 9, 2014Assignees: Suadi Arabian Oil Company, Boreskov Institute of CatalysisInventors: Abdennour Bourane, Omer Refa Koseoglu, Zinfer Ismagilov, Svetlana Yashnik, Mikhail Kerzhentsev, Valentin Parmon

Patent number: 4645587Abstract: Silicon components are removed from a hydrocarbon stream by contacting the stream with a sorbent comprising a mixture of a copper component and a porous, inorganic refractory oxide containing alumina. Preferably, the porous, inorganic refractory oxide will contain greater than about 10 weight percent alumina and most preferably consists essentially of alumina. It is normally desired to contact the hydrocarbon stream with the sorbent in the presence of molecular hydrogen in order to prevent coking of the sorbent. The sorbent may be a fresh mixture of the copper component and the porous, inorganic refractory oxide or it may be a spent sorbent prepared by using the fresh sorbent to remove sulfur components from a hydrocarbon stream. Alternatively, the sorbent may be a regenerated sorbent prepared by burning carbonaceous residues off a sorbent that was previously used to remove sulfur components from a hydrocarbon stream.Type: GrantFiled: December 7, 1984Date of Patent: February 24, 1987Assignee: Union Oil Company of CaliforniaInventor: Peter Kokayeff
