MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202647113029 A) filed by China Petroleum & Chemical Corporation; and Sinopec Research Institute Of Petroleum Processing on September 21, 2026, for Catalyst For Mass Production Of Propylene And Butene, And Preparation Method Therefor And Use Thereof.
Inventors include Wang, Lixia; Song, Haitao; Wang, Zhenbo; Zhou, Xiang; Cai, Kai; and Zhao, Liuzhou.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The present invention belongs to the field of catalytic cracking, and provides a catalyst, more specifically, a catalytic cracking catalyst for mass production of propylene and butene from wax oil distillate and a preparation method therefor. The catalyst comprises 45-80 wt% of a matrix and 20-55 wt% of a molecular sieve, wherein the molecular sieve comprises an MFI type molecular sieve and an optional FAU type molecular sieve, and the MFI type molecular sieve is newly developed particles, and is a ZSM-5 molecular sieve with higher hydrothermal stability, in which secondary particles are formed by the aggregation of primary particles. The catalyst is used for catalytic cracking of wax oil distillate, exhibits good hydrothermal stability and catalytic effect, and can significantly improve the yield of ethylene and propylene.
