黏合剂对其zsm-5分子筛成型物裂解石脑油的影响
, PP. 727-731
Keywords: zsm-5分子筛,黏合剂,石脑油,裂解,丙烯,乙烯
Abstract:
？为考察成型时,黏合剂性能对zsm-5分子筛的影响,对同一分子筛用六种不同黏合剂捏合,挤条成型,进行sem、nh3-tpd和n2物理吸附表征。结果表明,六个成型物在形貌和bet比表面积均无明显差异,二次孔数量明显比分子筛原粉增加。所用纯硅溶胶黏合剂的成型物,其nh3-tpd酸量、微孔体积和微孔比表面积低于其分子筛原粉。所用含铝黏合剂的成型物,其nh3-tpd酸量、微孔体积和微孔比表面积变化不明显,bjh累积孔体积明显增加。在固定床反应器中于600℃裂解石脑油。发现,纯硅溶胶黏合剂成型物的乙烯+丙烯收率明显低于含铝黏合剂。
