| 摘 要： | 以半纤维素为添加剂对HZSM-5分子筛进行改性,采用XRD、SEM、N2物理吸附-脱附、NH_3-TPD及Py-FTIR手段对其形貌、织构、酸性进行研究。并以丁烯齐聚为探针反应,考察半纤维素改性HZSM-5分子筛对低碳烯烃齐聚的催化能力。结果表明,当半纤维素质量分数为1.6%时,改性分子筛的比表面积、介孔体积最大,酸性最强,催化丁烯齐聚反应表现出了明显的优势,反应140 h转化率仍维持在80%左右,且三聚、四聚产物最多,柴油组分选择性最高。

| Abstract: | The HZSM-5 synthesized with modifying by different contents of hemicellulose.The morphology, texture and acidity were characterized with XRD, SEM, N2 adsorption-desorption, NH3-TPD and Py-FTIR. Butene oligomerization over the modified HZSM-5 was tested. The results indicate that the HZSM-5 with the 1.6% hemicellulose exhibits the best activity and stability on the butene oligomerization reaction, the conversion can maintain about 80% after 140 h on stream, with the highest selectivities of the trimer, tetramer and diesel component in the products. These may be related with its high BET surface and mesoporous volume, and the strongest acidity. |
