| 摘 要： | 通过水热合成制备了S2O28-促进的含锆介孔分子筛S2O28-/ZrO2-MCM-41,通过模型反应获得了对酯化反应具有较高催化活性的催化剂制备工艺条件,结果表明:在550℃下焙烧3 h的介孔分子筛,具有较高的催化活性,且在甲醇用量与热解油质量0.3∶1的条件下,催化剂可重复使用3次,酯化率仍保持85%以上。通过XRD,N2吸附脱附以及FT-IR表征了催化剂结构,将该催化剂用于油脂裂解产物的三相催化酯化实验研究。结果表明:酯化处理可将桐油裂解油中羧酸转化成酯,有效降低羧酸含量,在降低了酸值的同时还增加了燃烧热值,提高了燃料油品质。

| Abstract: | The mesoporous molecular sieve S2O2-8/ZrO2-MCM-41 was synthesized for the esterification of pyrolytic oils.The optimum preparation conditions were obtained by model reactions.The structure of mesoporous molecular sieve was identified by XRD,N2-TPD and FT-IR.The activity of S2O2-8/ZrO2-MCM-41 was studied.It was found that the catalyst could be reused for 3 times and gave more than 85 % conversion. |
