Title
Shape-selective amination of EO over HZSM-5 for MEA and DEA
Abstract

Shape-selective amination of ethylene oxide over HZSM-5 was thoroughly investigated. TPD, FTIR and catalytic performance showed that HZSM-5 was more active than the sodium form. Relative selectivity of product was mainly controlled by the crystal size of ZSM-5. Surface modification such as silyation was effective for enhancing the shape selectivity. Among the catalysts tested in this study, HZSM-5 with SiO2/Al2O3 ratio being 76.7 exhibited the best performance. At 353 K and total pressure of 8.0 MPa the total selectivity of MEA and DEA was 97.6%, the yield reached 96.6%, the best performance achieved so far among EO amination.

Research results show that Brönsted acid plays a major role in the amination. Small crystalline zeolite having shortened pore passage and enriched pore mouths shows high catalytic activity. Silyation was effective for enhancing the relative selectivity of MEA and DEA. At 353 K and total pressure of 8.0 MPa the total selectivity of MEA and DEA was 97.6% on HZSM-5 (76.7), the yield reached 96.6%.
