Publication number: 20220017829Abstract: A process for converting a hydrocarbon feed to olefins includes passing the hydrocarbon feed to a distillation system to separate the hydrocarbon feed to produce a light gas stream, a plurality of distillate fractions, and a residue. The process further includes passing at least one of the distillate fractions to a steam catalytic cracking system that includes at least one steam catalytic cracking reactor that is a fixed bed reactor containing a nano-zeolite cracking catalyst. The steam catalytic cracking system contacts the one or more of the plurality of distillate fractions with steam in the presence of the nano-zeolite cracking catalyst, which causes steam catalytic cracking of at least a portion of hydrocarbons in the at least one distillate fraction to produce a steam catalytic cracking effluent comprising the olefins.Type: ApplicationFiled: July 20, 2020Publication date: January 20, 2022Applicant: Saudi Arabian Oil CompanyInventors: Emad Naji Al-Shafei, Mohammed Z.

Patent number: 11225612Abstract: Embodiments of the disclosure provide a method for producing light olefins from a hydrocarbon feed. The hydrocarbon feed and a water feed are introduced to a reactor to produce an effluent stream. The reactor is operated at a temperature and pressure such that cracking reactions occur in the reactor. The reactor includes a catalyst bed including a nanoscale zeolite catalyst having a crystal size ranging between 10 nm and 300 nm. The effluent stream includes the light olefins. The effluent stream is introduced to a first separator to produce a gas phase fraction and a liquid phase fraction. The gas phase fraction includes the light olefins. The liquid phase fraction is introduced to a second separator to produce a liquid hydrocarbon stream and a spent water stream.Type: GrantFiled: March 27, 2020Date of Patent: January 18, 2022Assignee: SAUDI ARABIAN OIL COMPANYInventors: Emad Naji Al-Shafei, Mohammed Z.
