MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517038757 A) filed by Dow Global Technologies Llc, Midland, U.S.A., on April 22, for 'methods for producing light olefins.'
Inventor(s) include Pretz, Matthew T.; Yang, Yang; 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: "Methods for forming light olefins in a reactor system may include reacting a feed stream in the presence of a particulate solid in a reactor to form a product stream. The reaction may form coke on the particulate solid. The method may include passing the particulate solid to the regenerator and burning at least a portion of the coke to heat the particulate solid; mixing air and supplemental fuel upstream of the regenerator to form a gas mixture and passing the gas mixture to the regenerator through a distributor; and combusting the supplemental fuel in the regenerator to heat the particulate solid; and passing the heated particulate solid from the regenerator to the reactor. A concentration of supplemental fuel in the gas mixture may be less than 80% of the lower explosive limit of the supplemental fuel in the gas mixture, and heat from burning the coke and the supplemental fuel may be sufficient to maintain a heat balance of the reactor system."
The patent application was internationally filed on Nov. 20, 2023, under International application No.PCT/US2023/080467.
