Patent number: 9605213Abstract: Embodiments of the invention provide a method for the fluid catalytic cracking of a heavy hydrocarbon feedstock. According to at least one embodiment, the method includes supplying the heavy hydrocarbon feedstock to a reaction zone having a catalyst, such that both the heavy hydrocarbon feedstock and the catalyst are in contact in a down-flow mode, wherein said contact between the heavy hydrocarbon feedstock and the catalyst takes place in a fluidized catalytic cracking apparatus having a separation zone, a stripping zone, and a regeneration zone. The method further includes maintaining the reaction zone at a temperature of between 500 and 600° C., such that the hydrocarbon feedstock converts into a cracked hydrocarbon effluent comprising light olefins, gasoline, and diesel.Type: GrantFiled: February 4, 2016Date of Patent: March 28, 2017Assignees: SAUDI ARABIAN OIL COMPANY, KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Musaed Salem Al-Ghrami, Cemal Ercan, Sulaiman S.

Patent number: 9403155Abstract: The present invention concerns a novel additive composition for reducing sulfur content of a catalytically cracked gasoline fraction. This additive composition comprises a support consisting of porous clay into which a first metal from group IVB is incorporated and a second metal from group IIB is impregnated. Preferably, the first incorporated metal is zirconium and the second impregnated metal is zinc. The sulfur reduction additive is used in the form of a separate particle in combination with a conventional cracking catalyst in a fluidized catalytic cracking process to convert hydrocarbon feed stocks into gasoline having comparatively lower sulfur content and other liquid products.Type: GrantFiled: February 7, 2013Date of Patent: August 2, 2016Assignees: SAUDI ARABIAN OIL COMPANY, KING FAHD UNIVERSITY OF PETROLEUM AND MINERALInventors: Christopher F.

Publication number: 20130165315Abstract: The method of forming a hydrocarbon cracking catalyst provides a method of varying or tuning the mesophase MCM-41 or microporous ZSM-5 properties in biporous ZSM-5/MCM-41 composites, depending on the requirements of the intended application. The method includes the steps of performing a surfactant-mediated hydrolysis of ZSM-5 to form a solution, and then adjusting the pH of the solution to selectively tune the microporous and mesoporous properties of the final ZSM-5/MCM-41 catalyst product. Following tuning, soluble aluminosilicates are hydrothermically condensed to form a mesoporous material over the remaining ZSM-5 particles to form the ZSM-5/MCM-41 composite. The ZSM-5/MCM-41 composite may be used as a hydrocarbon cracking catalyst for cracking gas, oil or the like.Type: ApplicationFiled: December 27, 2011Publication date: June 27, 2013Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: SULAIMAN S.
