Patent number: 10583423Abstract: Embodiments of processes for producing propylene utilize a dual catalyst system comprising a mesoporous silica catalyst impregnated with metal oxide and a mordenite framework inverted (MFI) structured silica catalyst downstream of the mesoporous silica catalyst, where the mesoporous silica catalyst includes a pore size distribution of at least 2.5 nm to 40 nm and a total pore volume of at least 0.600 cm3/g, and the MFI structured silica catalyst has a total acidity of 0.001 mmol/g to 0.1 mmol/g. The propylene is produced from the butene stream via metathesis by contacting the mesoporous silica catalyst and subsequent cracking by contacting the MFI structured silica catalyst.Type: GrantFiled: July 19, 2018Date of Patent: March 10, 2020Assignees: Saudi Arabian Oil Company, King Fahd University of Petroleum & MineralsInventors: Sulaiman Saleh Al-Khattaf, Arudra Palani, Tazul Islam Bhuiyan, Sohel Shaikh, Mohammad Naseem Akhtar, Abdullah M.

Publication number: 20170327750Abstract: A method of cracking a hydrocarbon feed which includes introducing vaporizing a hydrocarbon feed and a heat generating material (HGM) stream comprising at least one aldehyde or ketone to a cracking reactor. The hydrocarbon feed and the HGM stream are vaporized and may be vaporized prior or subsequent to introduction to the cracking reactor. The addition of the HGM to the endothermic cracking process provides the heat needed for cracking and helps the overall process to achieve thermal neutrality. The method includes cracking the hydrocarbon feed to produce a cracking product, where the cracking product comprises C1-C4 hydrocarbons and C5+ hydrocarbons.Type: ApplicationFiled: May 2, 2017Publication date: November 16, 2017Applicant: Saudi Arabian Oil CompanyInventors: Hussein Mohammed Al Yami, Miao Sun, Ola Ali, Wei Xu
