| 摘要:采用甲醇蒸气重整制氢技术，设计在线重整醇氢供给系统，以改善氢气储运问题。基于SR-DE反应机理，在Aspen Plus软件中建立全混流反应器模型，通过灵敏度分析法优化工艺参数：操纵变量为反应温度（150~350 ℃）、水醇比（1.0~2.0）、压力（0.101 3~3.039 0 MPa），采集变量为甲醇转化率、H?及CO摩尔分数。结果表明：在常压、200 ℃、水醇比为1.4条件下，甲醇转化率>99%，H?摩尔分数>70%。根据供给系统的工作需求，完成了系统方案设计与关键部件选型设计。该供给系统满足TBD234V8型发动机在100%负荷下掺氢比为20%的需求。 |

| Abstract:To improve the storge and transportation of hydrogen，hydrogen production by methanol steam reforming（MSR）technology can be used to design on-site reforming methanol hydrogen supply system.Based on the SR-DE reaction mechanism，a fully mixed-flow reactor model was established in Aspen Plus.The process parameters were optimized by sensitivity analysis：the operating variables were reaction temperature （150-350 ℃），water-methanol ratio（1.0-2.0）and pressure（0.101 3-3.039 0 MPa），and the acquisition variables were methanol conversion rate，H2 and CO mole fractions.The results show that under the conditions of atmospheric pressure，200 °C and water-alcohol ratio of 1.4，the methanol conversion rate is higher than 99 %，and the mole fraction of H2 is larger than 70%.According to the working requirements of the supply system，the scheme design of the system and the selection design of key components were completed.The supply system meets the demand of 20% hydrogen blending ratio of TBD234V8 engine under 100% load. |
