Keyword:  哈德原油350~520℃减压馏分润滑油指标催化裂化原料;
Abstract: 实沸点切取350~400℃、400~450℃、450~520℃三个馏分按润滑油指标进行性质分析,表明哈德原油低黏度润滑油收率高,为9.25%,且粘度指数很高,达到了137,表明该馏分是高黏度润滑油难得的优质原料.硫含量、酸值、凝点不合要求,须经深度脱蜡和精制.把350—520℃馏分按催化裂解原料进行分析,表明哈德原油减压馏分平均分子中烷基侧链上的碳原子百分数Cp为77.36%.重金属镍+钒含量少(0.03ug/g),是理想的催化裂化原料.在加压微反色谱装置上对哈德原油350~520℃馏分进行催化裂化实验,结果表明该馏分是优质的催化裂化原料,其转化率高达75.49%,轻质油收率高达69.46%,液化气收率高达24.43%,超出一般催料很多,加工时要注意稳定塔顶压力超高.
