SSZ-13和 SAPO-34对乙醇脱水制乙烯反应的对比研究
Comparative study on catalytic performance of ethanol dehydration to ethylene of SSZ-13 and SAPO-34
摘要
Abstract
SSZ-13 catalyst was synthetised with N, N, N -trimethyl alkyl ammonium hydroxide as template. SAPO -34 molecular sieve was synthetised with triethylamine (TEA) . The the catalysts were characterized by XRD, SEM, low-temperature N2 adsorption. Then studied the catalytic properties of ethanol dehydration reactions at different conditions for the catalyst prepared in a fixed bed reactor were studied. The results indicate that the prepared SSZ-13 molecular sieve belongs to chabazite structure, in the process of ethanol dehydration to ethylene, the average conversion of ethanol and average selectivity of ethylene is 98.8% and 99.2% at 350 ℃ . In the same conditions, the average conversion of ethanol and average selectivity of ethylene is 78.2% and 53.5% when using SAPO-34 molecular sieve as a catalyst of ethanol dehydration to ethylene.关键词
