| 中文摘要: |
| 以HY、HZSM-5、MCM-41分子筛为催化剂，通过向餐厨废油中添加5%的乙醇或丙酮进行共裂化反应制备生物基燃料油，对液体产物的品质指标进行了测定，并对其成分进行了GC-MS分析。结果表明：在HY和MCM-41催化条件下，添加醇/酮后裂化反应优化效果明显，液体产物密度、酸值、皂化值均降低，产率升高，催化剂结焦率和产气量均降低，而在HZSM-5催化条件下，优化效果不明显；GC-MS分析表明，在添加乙醇后液体产物中烷烃含量增加到24.93%，添加丙酮后液体产物中芳香烃含量增加到70.27%，含氧化合物含量降低至2.38%。研究表明催化裂化时加入醇/酮可以在不同程度上改善生物基燃料油的产品品质，并对生物基燃料油的成分种类起到很强的选择性。 |
| 英文摘要: |
| HY, HZSM-5 and MCM-41 molecular sieve were used as catalysts to conduct co-cracking test for preparation of bio-based fuel oil by adding 5% ethanol or acetone in waste cooking oil, and the quality indexes and components of the liquid products were determined and analyzed by GC-MS, respectively. The results showed that under HY and MCM-41 catalytic conditions, the cracking reaction optimization effect after adding alcohol or ketone was obvious, the density, acid value, saponification value of the liquid products and coking rate of catalyst were reduced, the yield was increased, and the gas production was reduced, while under HZSM-5 catalytic conditions, the optimization effect was not obvious. GC-MS analysis result of the liquid products showed that the alkane content increased to 2493% after the addition of ethanol, the aromatic hydrocarbon content increased to 70.27% and the oxygen-containing compound content decreased to 2.38% after the addition of acetone. The research showed that the addition of alcohol or ketone could improve the product quality of bio-based fuel oil in different degrees and had a strong selectivity to the composition of bio-based fuel oil. |
