摘　　要：以三乙醇胺为模板剂，采用静态晶化水热法合成出一种特殊结构的沸石分子筛（称作ＳＡＯ－５），合成过程中不易发生混晶和转晶，重复性良好。对ＳＡＯ－５沸石进行了物相分析和红外光谱研究，考察了它的吸附性能和酸性。在ＳＡＯ－５沸石分子筛上进行正构烷烃（ｎ－Ｃ６）裂解反应测试，显示出较高的催化活性；在重油裂解反应测试中，显示出很高的Ｃ＝３。A new crystal phase SAO5 zeolite was synthesized by static hydrothermal method using triethanolamine as template. Mixing and transformation of crystal phase are hardly liable to occur in the synthesis process, wich can thus be performed with good repeatability. SAO5 zeolite is characterized by phase analysis and IR spectroscopy to investigate its adsorbability and acidity. Experiment on nC6 cracking reaction over SAO5 zeolite molecular sieve showed higher catalytic activity, while experiment on heavy oil cracking reaction showed good selectivity to C3 and C4 olfins.
