摘要/Abstract

摘要： 利用Aspen Plus软件建立了生物油裂解气费托合成-烯烃齐聚耦合制取航煤组分的仿真流程，得到整个系统的物流、能流数据。对整个系统进行了(火用)分析，找出(火用)效率最高、(火用)损失最大的单元，研究了不同催化裂解温度和不同航煤生产工艺下系统的(火用)效率。结果表明：催化裂解温度为550℃时，系统的总(火用)效率为80.4%，水煤气变换子系统具有最高的(火用)效率，费托合成-烯烃齐聚耦合子系统具有最大的(火用)损失，占全部(火用)损的75.88%；生物油催化裂解温度从500℃上升到650℃，系统的总(火用)效率由87%下降到76.9%；合成气的组成对系统的(火用)效率影响不大，3种不同的航煤生产方式中，烯烃齐聚具有最高的(火用)效率；费托合成-烯烃齐聚耦合工艺的改进应集中在开发新型反应器以及寻找同时适用于两种反应的催化剂。

Abstract: The process of jet fuel production by combining the Fischer-Tropsch synthesis with olefin polymerization from bio-oil cracking gas was simulated using Aspen Plus software;and the flow data of the whole system was obtained. Exergy analysis of the whole system was performed to find the units with the highest exergy efficiency and the largest exergy loss. The exergy analysis of the whole system was conducted under the different catalytic cracking temperatures and jet fuel production processes. The results showed that,when the catalytic cracking temperature was 550℃,the whole exergy efficiency of the system was 80.4%;the water-gas shift system had the highest exergy efficiency;the coupling of Fischer-Tropsch synthesis and olefin polymerization system had the largest exergy loss,accounting for 75.88% of the total exergy loss. When the catalytic pyrolysis temperature increased from 500℃ to 650℃,the whole exergy efficiency of the system was reduced from 87% to 76.9%;the composition of the syngas had little impact on the exergy efficiency of the system. Olefin polymerization system had the highest exergy efficiency in the three different ways of producing jet fuel;the further improvement of the coupling of Fischer-Tropsch synthesis and olefin polymerization process should focus on the development of new reactors and the new catalysts for both reactions.
