| 中文摘要: |
| 开发可再生的生物液体燃料可以增加能源供应,减轻环境污染。本文以生物柴油加氢脱氧得到的生物烷烃为原料,采用Pt/Al-MCM-41为加氢裂化催化剂制备生物航空煤油。试验以硅铝比为10的Al-MCM-41为载体,通过改变Pt负载量,制备了金属/酸性不同配比的催化剂。在配比值CPt/CA为0.182～0.338范围内,随着CPt/CA值的增加,催化剂的加氢裂化活性和对煤油的选择性均逐渐增加,但太高的CPt/CA值会引起Pt颗粒团聚,不仅造成催化剂浪费而且会降低催化活性和对煤油的选择性。CPt/CA为0.203是较理想的配比值。 |
| 英文摘要: |
| The development of renewable liquid biofuel is a crucial route to increase the energy supply and reduce the pollutant emission. The catalysts were tested in the hydrocracking of bio-alkanes, produced from biodiesel hydrodeoxygenation for the production of bio-jet fuel. The ratio of metal sites to acid sites (CPt/CA) on Pt/Al-MCM-41 bifunctional catalyst is important to both the catalyst activity and product selectivity. Catalysts with different metal/acid ratios were prepared on Al-MCM-41 support with Si/Al ratio of 10 using various platinum loadings. Both the hydrocracking activity and selectivity to kerosene increased with the increase in CPt/CA ratio in the range of 0.182–0.338. However, too high metal/acid ratio could cause the agglomeration of platinum particles, resulting in the waste of catalyst and reduction of catalyst activity and selectivity to kerosene. The optimal metal/acid ratio was about 0.203. |
