MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517039647 A) filed by Dow Global Technologies Llc, Midland, U.S.A., on April 24, for 'methods for producing olefinic compounds utilizing regenerators.'
Inventor(s) include Luo, Lin; Wang, Hangyao; Pretz, Matthew T.; Yuan, Quan; and Li, Liwei.
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 of producing olefinic compounds may include contacting a feed stream including one or more hydrocarbons with a particulate solid catalyst in a reactor. In the reactor, the one or more hydrocarbons may be dehydrogenated to form one or more products including one or more olefinic compounds and at least a portion of the particulate solid catalyst may be deactivated. The method may also include passing at least a portion of the deactivated particulate solid catalyst to a combustor. In the combustor, a supplemental fuel stream may enter the combustor through a supplemental fuel distributor and the supplemental fuel stream may be reacted to heat at least a portion of the deactivated particulate solid catalyst. The method may also include passing at least a portion of the heated deactivated particulate solid catalyst to an oxygen treatment zone to produce a reactivated particulate solid catalyst. The method may also include passing at least a portion of the reactivated particulate solid catalyst back to the combustor. In the combustor, the reactivated particulate solid catalyst may enter the combustor downstream of the supplemental fuel stream relative to a flow direction of the supplemental fuel steam and the deactivated particulate solid catalyst may enter the combustor upstream of the supplemental fuel stream relative to the flow direction of the supplemental fuel stream. The method may also include passing at least a portion of the reactivated particulate solid catalyst to the reactor."
The patent application was internationally filed on Nov. 27, 2023, under International application No.PCT/US2023/081078.
