【摘要】：为了验证吸附强化焦炉荒煤气重整制氢工艺的可行性,并为相关的实验研究提供理论依据,文章采用HSC Chemistry软件对焦炉荒煤气全组分蒸汽重整反应进行热力学分析,研究反应温度、反应压力、S/C,CaO/C对H_2产率、浓度等的影响。研究结果表明:焦炉荒煤气蒸汽重整反应能够有效地脱除焦油组分,随着S/C的增大,H_2产率会得到明显提升,且最佳H2产率所对应的反应温度会随之降低,当S/C为5∶1,反应温度为700℃时,H_2产率为1.62 mol/mol,但H_2浓度仅为75%左右;CO_2吸附剂的加入会强化蒸汽重整反应,H_2产率、浓度均会显著提升,最佳重整反应区的反应温度会随之降低,当反应温度为500~600℃,S/C为5∶1,CaO/C为3∶1时,H2产率、浓度能够分别达到1.83 mol/mol,98%以上。
[Abstract]:In order to verify the feasibility of adsorption enhanced reforming of coke oven gas for hydrogen production and to provide theoretical basis for related experimental research, the thermodynamic analysis of steam reforming reaction of coke oven waste gas is carried out by using HSC Chemistry software. The effects of reaction temperature, reaction pressure and S / C / Cao / C on the yield and concentration of H _ 2 were studied. The results show that the steam reforming reaction of coke oven waste gas can effectively remove the tar component. With the increase of S / C, the yield of H _ 2 will be obviously increased, and the reaction temperature corresponding to the optimum H _ 2 yield will decrease. When S / C is 5: 1 and the reaction temperature is 700 鈩，
