随着全球经济的不断发展，轻质油资源已不能满足世界各国的需要，重质稠油则由于粘度高、流动性差而难以开采，因此，高效率、低能耗、低成本的开采方法，是目前国内外所关注的问题。催化降粘是一种通过向稠油添加催化剂，使稠油在地下发生催化反应的方法，由于稠油的胶质、沥青质发生裂解，饱和烃、芳烃增多，油品粘度能够大幅下降，受到了众多研究者的关注。国内外已开发的催化剂主要为水溶性过渡金属盐催化剂、油溶性过渡金属盐催化剂、超强酸催化剂及杂多酸催化剂。本文选择镍、铁为金属活性中心，制备出2,2’-联吡啶为配体的联吡啶类催化剂及油酸镍催化剂，分别用于胜利油田1#稠油和2#稠油的降粘实验研究，取得了以下主要结果：在24...With the continuous development of global economy, light oil can not meet the needs of countries all over the world, while heavy oil is difficult to exploit due to its high viscosity and poor fluidity. Therefore, it’s in the limelight to develop visbreaking techniques of heavy oil with high efficiency, low energy consumption and cost. At present, a catalytic visbreaking technique is receiving more...学位：工学硕士院系专业：化学化工学院化学工程与生物工程系_工业催化学号：20043302
