摘　　要：利用高温高压反应釜研究了自制油溶性有机镍盐作为催化剂的稠油水热裂解反应,考察了催化剂的加入量、反应温度、反应时间和加水量对催化水热裂解反应前后稠油黏度、族组成的影响,优选出最佳改质降黏反应条件,在此条件基础上,对改质降黏反应前后稠油元素进行分析。结果表明,与未添加催化剂的相比,在反应温度为240℃、加水量30%的体系中,添加0.1%的过渡金属有机酸镍催化剂,反应24 h后稠油的黏度下降明显,沥青质含量下降1.4%,胶质含量下降5.0%,芳香分含量增加3.5%,饱和分含量增加2.9%.This paper studied the self-made organic oil soluble nickel salt as a catalyst by which the aquathermolysis reaction of heavy oil is conducted using high temperature autoclave,and investigates the effects of catalyst requirement,reaction temperature,reaction time and injected water on the heavy oil viscosity and group composition before and after such a reaction,and then selects the optimum reaction condition for the viscosity reduction.Based on this condition,the heavy oil element before and after that is analyzed.The results show that after 24 h reaction and adding 0.1wt% catalyst of organic acids nickel,the viscosity of heavy oil decreased distinctly at reaction temperature of 240℃ and additive water amount of 30wt%,with the decreases of Asphaltene content by 1.4wt%,colloid content by 5.0wt%,and the increases of aromatic content by 3.5wt% and saturated component content by 2.9wt%.
