采用悬浮床加氢技术和水溶性分散催化剂对辽河坨子里稠油的常压渣油进行了轻质化和改质研究。对催化剂金属组成、催化剂应用条件和过程生焦及转化率的关系进行了系统考察，试验结果经数学处理后得到各关系曲线。研究结果表明，在催化剂加入量２５０μｇ／ｇ、反应温度４３５℃、反应空速１．０ｈ－１和１０ＭＰａ条件下单程通过反应处理坨子里常压渣油得到轻柴油和减压馏分油的质量收率分别为３１．２％及４０．７％。 The use of suspended bed hydrogenation technology and water-soluble dispersed catalyst Liaohe Tuozi heavy oil atmospheric residue was light and modified. The relationship between the catalyst metal composition, the catalyst application conditions and the process coke and the conversion rate was systematically investigated. The experimental results obtained after the mathematical treatment of the relationship curve. The results show that the quality of light diesel oil and vacuum distillate oil can be obtained by one-way reaction treatment of atmospheric residue with the addition of catalyst 250μg / g, reaction temperature 435 ℃, reaction space velocity 1.0h-1 and 10MPa The rates were 31.2% and 40.7% respectively.
