摘　　要：采用不同的分散方式及分散方法,考察了辽河稠油渣油混合油加氢裂化水溶性催化剂的分散行为,建立了分散性能参数来评价水溶性催化剂在重油中的分散效果。实验结果表明:水溶性催化剂的催化活性随其分散度的增加而增大,分散方式和分散方法对加氢裂化的影响很大;相反,分散时间、速度超过一定值后对催化剂的分散效果影响不大。研究发现,分散性能参数与混合油加氢裂化反应结果存在相关性。The dispersion behavior of water-soluble catalyst for hydrocracking of Liaohe heavy oil and resi- due mixture was studied by different dispersion modes and methods.The dispersion performances of water-sol- uble catalyst in heavy oil were evaluated by dispersion parameter.The results indicated that the activation of water-soluble catalysts for residue hydrocracking increases with the increment of the dispersion degree.The dispersion modes and methods have a great impact on hydrocracking reaction.When the dis...
