Inventor(s) include Luo, Lin; Wang, Hangyao; Pretz, Matthew T; Yuan, Quan; Li, Liwei; and Ferrio, Jeffry A.
The application for the patent was published on June 13, under issue no. 24/2025.
According to the abstract released by the Intellectual Property India: "A method for producing one or more olefinic compounds may include dehydrogenating a feed stream in the presence of a catalyst in a reactor to form a product stream and a deactivated catalyst. The feed stream may include one or more hydrocarbons comprising an alkyl moiety. The product stream may include one or more olefinic compounds. The method may also include separating the deactivated catalyst into a first portion of deactivated catalyst and a second portion of deactivated catalyst. The method may include passing the second portion of deactivated catalyst to a regenerator. The method may include processing the second portion of deactivated catalyst in the regenerator to form a regenerated catalyst. The method may also include passing the first portion of deactivated catalyst and the regenerated catalyst to the reactor. The first portion of deactivated catalyst may enter the reactor downstream of the regenerated catalyst relative to the flow direction of the feed stream. The first portion of deactivated catalyst may have a lower temperature than the regenerated catalyst."
The patent application was internationally filed on Nov. 27, 2023, under International application No.PCT/US2023/081074.
