【摘要】 利用超临界水 合成气为替代加氢氢源对孤岛渣油悬浮床加氢裂化反应进行了研究,设想利用超临界水中发生的水 气转化反应(CO+H2O→H2+CO2)为渣油加氢反应提供氢源,报道了孤岛渣油超临界水 合成气中悬浮床加氢裂化反应催化剂影响的研究结果。结果表明,催化剂在该反应中具有十分重要的作用,加入催化剂可以明显改善加氢裂化产物的分布和裂化反应产物的性质,降低裂化气体和抑制缩合生焦反应的发生。更多还原

【Abstract】 The heavy oil upgrading technology with alternative hydrogen is very attractive for the heavy oil processing. The catalytic hydrocracking of Gudao residue with different catalysts precursors using water-syngas as alternative hydrogen was investigated, which provides hydrogen in-situ for hydrocracking through the water-gas shift reaction(WGSR). The results show that catalysts play a very important role in catalytic hydrocracking of Gudao residue using water-syngas as alternative hydrogen. Addition of catalysts to residue was found to improve the distribution of cracking products and inhibit the asphaltene or TI formation.更多还原
