Abstract: Nanosized ZSM-5 was synthesized and used for straight run gasoline reforming. Nanosized β was synthesized and used for the alkylation of benzene and ethylene in ethylbenzene production. Nanosized titanosilicate molecular sieve with a hollow structure (HTS) was synthesized and used for the oximation of cyclohexanone. Nanosized silicalite-1 was synthesized and used for the gas phase Beckmann rearrangement of cyclohexanone oxime in caprolactam production. Recent progress in the synthesis and application of nanosized ZSM-5, β, TS-1, and silicalite-1 were reviewed. The catalyst lifetimes were prolonged when nanosized molecular sieves were used as petroleum refining and petrochemical catalysts.

Key words: nanosized zeolite, ZSM-5, β, titanosilicate, silicalite-1, gasoline reforming, ethylbenzene, caprolactam
