| 中文摘要: |
| 以硅铝比30∶?1 的MCM-22和全硅的MCM-41分子筛作为催化剂、小桐子油为原料，在实验室自制的小型催化裂化反应装置中进行催化裂化制备燃料油实验。通过考察不同裂化温度、质量空速对催化裂化反应的影响，确定优化的反应条件。结果表明：MCM-22催化裂化的最佳工艺条件为裂化温度510?℃、质量空速5.25 h-1； MCM-41催化裂化的最佳工艺条件为裂化温度530?℃、质量空速5.25 h-1。MCM-22催化裂化后产物酸价（KOH）较低（1.32 mg/g），优于MCM-41催化剂；但MCM-41催化裂化小桐子油转化率较高，优于MCM-22 催化剂；两种催化剂催化裂化产物多为芳烃类化合物。 |
| 英文摘要: |
| MCM-22 zeolite with ratio of silica to alumina 30∶?1 and MCM-41 zeolite with all-silicon were used as catalysts, Jatropha curcas oil was used as raw material, the catalytic cracking tests to prepare fuel oil were carried out in small laboratory self-made catalytic cracking reactor. Through studing the effects of different cracking temperatures and mass hourly space velocities on the catalytic cracking reaction, the reaction conditions were optimized. The results showed that the optimal conditions of catalytic cracking by MCM-22 were obtained as follows: cracking temperature 510?℃ and mass hourly space velocity 5.25 h-1. For MCM-41, the optimal conditions were as follows: cracking temperature 530?℃ and mass hourly space velocity 5.25 h-1. The acid value of the product by MCM-22 was 1.32 mgKOH/g, which was superior to that by MCM-41. However, the conversion rate by MCM-41 was higher than that by MCM-22. The product was mainly composed of armatics. |
