摘要/Abstract

摘要： 选择1-甲基萘作为焦炉荒煤气中焦油组分的模型化合物，采用HSC Chemical软件对其蒸汽重整反应进行了热力学分析.研究发现，温度和S/C比(Steam/Carbon摩尔比)的增加能够促使H₂产量和浓度的增加，但是当温度或S/C比分别达到500℃，8∶1以上，H₂产量、浓度均变化不大；反应压力的增加不利于重整反应的进行，致使H₂产量降低，确定最佳的蒸汽重整反应压力为常压；当加入CaO作为CO₂吸附剂时，发现重整反应进程被强化，H₂产量、浓度均得到显著提升，当CaO/C比(CaO/Carbon摩尔比)为2∶1，S/C比为8∶1，温度在400~650℃时，H₂产率和体积分数均能达到95%以上.

Abstract: The thermodynamic analysis of the steam reforming of 1-methylnaphthalene as the tar model compound of the raw coke oven gas was carried out using the HSC Chemical software. With the increases of temperature and the steam/carbon (S/C) ratio， the amount and concentration of H₂ gradually increased， however their changes became gentle when the temperature passed 500℃ or the S/C ratio was over 8∶1.With the pressure increasing， the H₂ amount gradually decreased， therefore the optimal pressure for 1-methylnaphthalene steam reforming was the normal pressure. After CaO was added as CO₂ sorbent， the steam reforming reaction process was enchanced， resulting in the significant improvement of the H₂amount and concentration. With the CaO/C ratio of 2∶1 and S/C ratio of 8∶1， the H₂ amount and concentration could reach over 95% at the temperature of 400~650℃.
