| 摘 要： | 通过HZSM-5分子筛催化剂对生物油典型模型化合物(乙酸、愈创木酚、正庚烷和环己烷等)在550℃进行了催化裂化反应,研究模型化合物催化裂化特性和反应机理以及催化剂性质。结果表明,正庚烷和环己烷裂化产物主要是芳香烃(53%和91%,均为积分面积分数),对于此类不含氧的模型化合物,催化裂化反应过程更容易进行;随着催化剂用量的增加,可以有效增加乙酸裂化产物中芳香烃含量(12%到90%,均为积分面积分数);愈创木酚结构比较复杂,HZSM-5催化剂主要脱除了甲氧基,催化剂用量的增加可以使芳香烃类稳定物质更容易形成。

| Abstract: | Catalytic cracking experiments were performed for bio-oil model compounds (acetic acid, guaiacol, n-heptane and hexamethylene, etc) using HZSM-5 molecular sieve catalyst at 550℃, aiming to study the reaction mechanism and catalyst properties. The results show that the main product for catalytic cracking of n-heptane and hexamethylene is aromatics (53% and 91%, respectively in area). Catalytic cracking reaction occurs more easily for those oxygen-free model compounds. The aromatics content increase effectively (from 12% to 90% in area) with increasing addition of catalyst for acetic acid. The guaiacol structure is quite complex and the catalyst mainly removes its methoxy group. Increasing the weight of catalyst could lead to aromatics formation more easily. |
