Nanosized molecular sieves as petroleum refining and petrochemical catalysts

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.

Nanosized ZSM-5, β, HTS, and silicalite-1 zeolites were synthesized and used, respectively, for straight run gasoline reforming, alkylation of benzene and ethylene, oximation of cylcohexanone, and gas phase Beckmann rearrangement of cylcohexanone oxime. The catalyst lifetimes were prolonged when nanosized molecular sieves were used.Figure optionsDownload as PowerPoint slide
