| 摘要: |
| 以蒽为稠油多环芳烃模型化合物,考察了不同条件下蒽对CO水热变换新生氢的富存影响,并对CO水热变换和蒽储氢之间的协同效应进行了分析。研究表明,Fe(NO3)3·9H2O和环烷酸铁对蒽富存CO水热变换新生氢均有催化作用,Fe(NO3)3·9H2O的作用效果更好。随着反应温度、CO初始压力和加入的Fe(NO3)3·9H2O中铁含量的增加,CO转化率和蒽储氢效率均呈现逐渐增大的趋势。CO初压2 MPa,Fe(NO3)3·9H2O中铁的质量分数为0.08%时,对蒽储氢反应较为适宜,储氢效率较高。蒽储氢可对CO变换产生的新生氢进行富存,从而消耗新生氢,进而促进CO水热变换反应。因此,蒽储氢与CO水热变换反应之间存在正协同效应,二者相互促进。 |

| Abstract: |
| The effect of anthracene hydrogenation with CO water gas shift as a model for polycyclic aromatic hydrocarbons under different conditions was investigated, and the synergistic effect between anthracene hydrogenation and WGSR (water gas shift reaction) was also analyzed. The results showed that Fe(NO3)3·9H2O and iron naphthenate are catalytic active for anthracene hydrogenation with CO water gas shift, but Fe(NO3)3·9H2O is the better one. The conversion of CO water gas shift and anthracene hydrogenation increase with the increasing of CO initial pressure, reaction temperature and the concentration of Fe in Fe (NO3)3·9H2O. The conversion of anthracene hydrogenation is substantial when the concentration of Fe in Fe(NO3)3·9H2O is 0.08 wt% and CO initial pressure is 2 MPa. Anthracene hydrogenation consumed H2 generated from WGSR to promote WGSR, so there is a positive synergy between anthracene hydrogenation and WGSR. |
