孤岛渣油超临界水-合成气中悬浮床加氢裂化反应研究 Ⅰ. 催化剂的影响

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.
