摘要: 本发明涉及到一种氧化铝包裹分子筛的复合载体、加氢裂化异构化催化剂及其制备方法和应用。先通过对分子筛进行氨基酸扩孔处理,之后对分子筛进行磺化处理,之后将磺化的分子筛加入到含有十六烷基三甲基溴化铵的醇水溶液中,再加入铝源和尿素,通过晶化、洗涤、干燥、焙烧得到复合载体,这种复合载体具有丰富的孔道,以及大量的酸性位点,使得加氢异构化性能高。此催化剂采用Pt、Pd、Ni、Co作为主要活性金属,Na、K、Be、Mg、Ca、Sr、Cr、Mn、Fe、Cu、Zn作为助剂金属,助剂金属不仅可以提高活性金属的分散度,还能对分子筛的酸性位点进行选择性的覆盖和抑制,对加氢活性起到了关键性的作用,在长链烷烃加氢异构制备生物燃料方面具有较高的活性。
