| 摘 要： | 在剂油比1：100时，焦化蜡油经过PDN型络合脱氮剂处理，其碱氮脱除率达到64．3％．脱氮油收率达到97．3％。在小型催化裂化装置上的评价结果表明．相同条件下以焦化蜡油为原料时，络合脱氮-催化裂化组合工艺与单纯催化裂化工艺相比．轻油收率提高了7．65％．总液体收率提高了9．80％。可见焦化蜡油络合脱氮后．降低了对催化裂化催化剂的毒害作用．提高了轻油收率。

| Abstract: | The coke wax oil is treated by PDN denitrifying agent,the rate of removing nitrides is 64.3% and the yield of the denitrifying wax oil is 97.3% when dose-oil ratio is 1∶100.The evaluation results of small-scale unit of FCC indicate that the yield of the light fuel oil distillate increased by 7.65% and the total yield of the liquid fuel oil distillate increased by 9.80% at the same condition by comparing combined process of the complex denitrifying and FCC with the pure FCC treating.Treating coke wax oil by complexing denitrifying reaction,it decreases the poison of FCC catalysts and increases the yield of the light fuel oil. |
