| 摘 要： | 为了研究替代氢源加氢的有效性,对孤岛渣油以磷钼酸为催化剂,在不同氢源(CO+H2/H2O、CO/H2O、H2/H2O、H2)中悬浮床加氢裂化反应进行了研究。结果表明,超临界水中现场发生的水-气转化反应提供的加氢氢源是一种具有高加氢活性的原子态氢。在适宜的反应条件下,孤岛渣油在超临界水-合成气中的加氢裂化反应过程在抑制生焦、反应产物分布等方面与对应的分子氢存在下孤岛渣油加氢裂化反应结果几乎一致,反应体系中水的存在主要作用是提供水-气转化反应的条件,在没有水-气转化发生的体系中,水的存在对加氢过程有抑制作用,总之、利用现场发生水-气转化反应为加氢提供氢源的孤岛渣油超临界水-合成气中悬浮床催化加氢裂化是一项有效的渣油加氢改质技术。

| Abstract: | The hydrocracking of Gudao residue in supercritical water using different hydrocracking media (CO+H_2/H_2O, CO/H_2O, H_2/H_2O, H_2) and in situ generated hydrogen from water gas shift reaction(WGSR)in the presence of dispersed catalyst precursor phosphomlybdic acid (PMA) was investigated. The results show that catalytic hydro-con- version of Gudao residue using in situ generated hydrogen is an effective upgrading technology for heavy oil. In situ generated hydrogen from WGSR is more reactive than the supplied molecular hydrogen for residue hydro-conversion. Under the proper reaction conditions, the hydro-conversion of residue in supercritical water-syngas system is similar to hydro-conversion of residue with the supplied molecular hydrogen. |
