摘要: β沸石首次为美国Mobil公司所合成[1],其骨架结构具有三维12元环孔道(两维线性,一维非线性)[2]。与Y型分子筛相比,β沸石具有更高的热稳定性和耐酸性,对加氢裂化,加氢异构化,裂解,芳构化等反应有良好的催化性能。人们过去着重研究沸石的表面酸性质,本文报道粒度对沸石吸附与扩散的影响。

Abstract: The beta-zeolites of various crystal size were synthesized by hydrothermal crystallization. The effects of crystal size on the adsorption and diffusion on zeolite have been evaluated and discussed using cyclohexane,n-hexane and benzene as adsorbate.

Key words: beta zeolite, adsorption, diffusion
