Patent number: 10232285Abstract: A system and method of cracking hydrocarbon feedstocks is provided that allows for significant flexibility in terms of the desired product yield. An integrated process includes introducing the feedstock and hydrogen into a first hydrocracking reaction zone containing a first hydrocracking catalyst to produce a first zone effluent. The first zone effluent is passed to a fractionating zone to produce at least a low boiling fraction and a high boiling fraction, and optionally one or more intermediate fractions. The bottoms fraction is conveyed to a fluidized catalytic cracking reaction and separation zone, from which olefins and gasoline are recovered. At least a portion of remaining cycle oil is passed from the fluidized catalytic cracking reaction and separation zone to a second hydrocracking reaction zone containing a second hydrocracking catalyst to produce a second stage effluent.Type: GrantFiled: August 27, 2013Date of Patent: March 19, 2019Assignee: Saudi Arabian Oil CompanyInventors: Omer Refa Koseoglu, Musaed Muhammad Al-Thubaiti, Ali Mahmood Al-Somali

Patent number: 9334451Abstract: A hydrocarbon feedstock is hydrocracked in a hydrocracking zone and the effluent is fractioned to recover a light fraction, a middle fraction containing aromatic compounds and a heavy fraction. The heavy fraction is recycled to the hydrocracking zone for further hydrocracking. The middle fraction is introduced to an aromatic separation zone. A product stream is recovered from the aromatic separation zone comprising a middle fraction having a reduced content of aromatic compounds as compared to the middle fraction recovered from the fractionator. Aromatics from the aromatic separation zone are recycled to the hydrocracking zone for further hydrogenation and cracking.Type: GrantFiled: March 15, 2010Date of Patent: May 10, 2016Assignee: Saudi Arabian Oil CompanyInventors: Omer Refa Koseoglu, Adnan Al-Hajji, Ali Mahmood Al-Somali, Hendrik Muller, Mohammed Abdullah Al-Ghamdi

Patent number: 9221036Abstract: The present invention relates to a hydrocracking catalyst for hydrocarbon oil comprising a support containing a framework-substituted zeolite-1 in which zirconium atoms and/or hafnium atoms form a part of a framework of an ultrastable y-type zeolite and a hydrogenative metal component carried thereon and a method for producing the same. The hydrocracking catalyst of the present invention makes it easy to diffuse heavy hydrocarbon oils such as VGO, DAO and the like into mesopores, is improved in a cracking activity and makes it possible to obtain a middle distillate at a high yield as compared with catalysts prepared by using zeolite comprising titanium and/or zirconium carried thereon.Type: GrantFiled: August 2, 2011Date of Patent: December 29, 2015Assignees: Saudi Arabian Oil Company, Japan Cooperation Center, Petroleum, JGC Catalysts and Chemicals Ltd.Inventors: Omer Refa Koseoglu, Adnan Al-Hajji, Ali Mahmood Al-Somali, Ali H.
