Patent number: 8105968Abstract: Solid acid catalysts for use in alkylation processes are described. The solid acid catalysts include a multimetallic (e.g. bimetallic, trimetallic or tetrametallic) component that performs a hydrogenating function for the reactivation (or regeneration) of the catalyst in the presence of hydrogen. The multimetallic catalyst includes a noble metal such as platinum or palladium. The invention also relates to alkylation processes using the multimetallic solid acid catalysts having a multimetallic component for hydrogenation.Type: GrantFiled: October 4, 2007Date of Patent: January 31, 2012Assignee: Lummus Technology Inc.Inventors: Anne Mae Gaffney, Philip Jay Angevine, Cheun Yuan Yeh, Johannes Hendrik Koegler, Jingguang Chen, Emanuel Hermanus van Broekhoven

Patent number: 8105969Abstract: A solid catalyst, such as a molecular sieve catalyst or solid acid catalyst, is supported by a binder, such as amorphous silica or alumina, wherein the binder is charged with metal ions to form an ion-modified binder. The ion-modified binder is capable of attachment to polar contaminants and inhibit their contact with the catalyst. The catalyst can be a zeolite and can be the catalyst for an alkylation reaction, such as the alkylation of benzene with ethylene.Type: GrantFiled: December 29, 2008Date of Patent: January 31, 2012Assignee: Fina Technology Inc.Inventors: Joseph E Pelati, Taylor Rives

Patent number: 8097764Abstract: A xylene isomerization process includes introducing gas comprising hydrogen and a base to a reaction zone in which a catalyst comprising a Group VIII metal and a zeolite support resides. In one embodiment, the base may be formed in situ within the reaction zone from nitrogen and hydrogen that are introduced to the reaction zone. In another embodiment, the base is introduced directly to the reaction zone. The conditions in the reaction zone are effective to reduce the catalyst. A stream comprising C8 aromatics, e.g., xylenes and ethylbenzene may then be fed to the reaction zone containing the reduced catalyst. The reaction zone may be operated at conditions effective to isomerize the xylenes and hydrodealkylate the ethylbenzene. The xylene loss during the isomerization of the xylenes is lowered as a result of using the catalyst reduced in the presence of the gas comprising a base and hydrogen.Type: GrantFiled: November 5, 2010Date of Patent: January 17, 2012Assignee: Chevron Phillips Chemical Company LPInventors: Scott H. Brown, Tin-Tack Peter Cheung

Patent number: 8062987Abstract: A zeolite catalyst that may be used in aromatic alkylation is prepared by treating a zeolite with a phosphorus compound. The phosphorus-treated zeolite is calcined and contacted with liquid water, whereby an amount of phosphorus is removed from the phosphorus-treated zeolite. The phosphorus-treated zeolite is then heated. A method of preparing an aromatic product may also be carried out by contacting the prepared zeolite catalyst with an aromatic alkylation feed of an aromatic compound and an alkylating agent under reaction conditions suitable for aromatic alkylation.Type: GrantFiled: October 5, 2009Date of Patent: November 22, 2011Assignee: Saudi Basic Industries CorporationInventors: Ashim Kumar Ghosh, Neeta Kulkarni, Pamela Harvey
