Inventors include Wang, Darui; Wang, Yiyan; Yang, Weimin; Sun, Hongmin; Shen, Zhenhao; Huan, Mingyao; Liu, Wei; and He, Junlin.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: Disclosed in the present invention are an MWW-type molecular sieve catalyst, a preparation method therefor and the use thereof. The catalyst may be a binderless molecular sieve catalyst. In intralayer 10-membered-ring channels of the molecular sieve, aluminum at T1, T3, T4, T5 and T8 which are five T sites in total accounts for =45% of aluminum at T1, T2, T3, T4, T5, T6, T5, T6, T7 and T8 which are eight T sites in total, and aluminum at the T2 site accounts for =23% of aluminum at T1, T2, T3, T4, T5, T6, T7 and T8 which are eight T sites in total. When used in the alkylation reaction of aromatic hydrocarbons and olefins to prepare alkyl aromatic hydrocarbons, the catalyst can effectively inhibit side reactions, has high activity and selectivity, and is applicable to a material feeding condition of lower molar ratios of aromatic hydrocarbons to olefins.
