摘要
文章采用HSC Chemistry软件进行多组分生物油重整制氢(包括普通重整和吸附强化重整)过程的热力学分析,研究反应温度、S/C和Ca/C对氢气浓度和氢气产率等指标的影响。研究结果表明:两种重整制氢过程的氢气产率和氢气浓度均随着S/C的增大而增大,但在S/C>3后增幅不再明显;当S/C=3时,普通重整制氢过程的氢气产率和氢气浓度均仅为70%左右,最佳重整反应温度高达830℃;加入吸附剂CaO后,吸附强化重整过程的氢气产率和氢气浓度较普通重整制氢过程有大幅提升,且最佳重整反应温度显著下降,当S/C=3时,最佳重整反应温度为480℃,氢气产率和氢气浓度分别为97.2%和99.7%。
In this paper, the thermodynamic analysis of H2 production from multicomponent bio-oil catalytic reforming process, including common reforming and adsorption-enhanced reforming, was carried out using the HSC Chemistry software. The effects of S/C, temperature and Ca/C on the hydrogen production were investigated. The results showed that the yield and concentration of H--2 increased along with the rise of S/C in the two processes, but the amplification was no longer obvious when S/C was higher than 3. When S/C was 3, the yield and the concentration of H2 in the common reforming were only about 70% and the optimal reaction temperature reached nearly 830 ℃. However,the addition of the CaO as CO2 sorbent can greatly increase the yield and concentration of H2, and the optimal temperature decreased significantly at the same S/C compared to the common reforming process. Particularly, when the S/C was 3 and the temperature was 480 ℃, the H2 yield can reach97.2%, with the concentration of 99.7%.
