MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202647127968 A) filed by China Petroleum & Chemical Corporation; and Sinopec Research Institute Of Petroleum Processing on October 27, 2026, for Method For Producing Olefins By Catalytic Dehydrogenation Of Alkanes And Corresponding Apparatus.
Inventors include Ma, Wenming; Gong, Jianhong; Tang, Jinlian; Yuan, Qimin; Zhang, Zhigang; and Zhu, Genquan.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention provides a method for producing olefins by catalytic dehydrogenation of alkanes and an apparatus. The apparatus comprises a reaction unit, a regeneration unit, and a product separation unit; the reaction unit comprises a pre-lift zone, an oil agent contact zone, a reaction zone, a product quenching zone, a reactor outlet zone, an oil agent separation zone, and a stripping zone. The oil agent contact zone is provided with a feeding distributor and a catalyst distributor, and an oil agent contact space is formed between the feeding distributor and the catalyst distributor, enhancing countercurrent contact between an alkane and a catalyst, and better facilitating the initiation of a catalytic dehydrogenation reaction. By bringing an alkane feedstock into contact with a catalyst and then leveraging the shape and parameters of the reactor, the present invention provides a proper reaction environment for a catalytic dehydrogenation reaction, thereby facilitating the catalytic dehydrogenation reaction, and improving the alkane conversion rate. In addition, the method and the apparatus of the present invention allow for alkane dehydrogenation reactions to be conducted under negative pressure, resulting in good safety and further improving alkane conversion rates and olefin selectivity.
