MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517039639 A) filed by Dow Global Technologies Llc, Midland, U.S.A., on April 24, for 'methods for forming dehydrogenated products utilizing combustion bypass of some catalyst.'
Inventor(s) include Nieskens, Davy; Pretz, Matthew T.; Goodfellow, Brian W.; and Malek, Andrzej.
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 dehydrogenated product may be formed by a method that includes reacting a feed stream in the presence of a catalyst by a dehydrogenation reaction in a reactor to form a dehydrogenated product, separating at least a portion of the product stream from the catalyst, separating the catalyst into at least a first catalyst portion and a second catalyst portion, and passing the first catalyst portion to a combustor. The first catalyst portion may be heated in the combustor by the combustion of supplemental fuel. The method may further include passing the first catalyst portion out of the combustor and combining the first catalyst portion with the second catalyst portion downstream of the combustor to form a recombined catalyst stream, such that the second catalyst portion bypasses the combustor. The method may further include passing the recombined catalyst stream through an oxygen treatment zone, and passing the recombined catalyst stream to the reactor."
The patent application was internationally filed on Nov. 22, 2023, under International application No.PCT/US2023/080921.
