ZHC-02单段加氢裂化催化剂的应用

Application of the Single Stage Hydrocracking Catalyst ZHC-02

ZHC-02催化剂是一种共胶法制备的无定型加氢裂化催化剂。它具有加氢活性好,异构性能强,中间馏分油选择性高和柴油馏分低温性能好等特点,适用于单段单剂一次通过或全循环加氢裂化工艺过程,最大量生产低凝点的中间馏分油产品。1999年7月在大庆石化分公司炼油厂26万t/a加氢裂化装置上进行工业应用试验,并连续运转3年。试验结果表明,ZHC-02催化剂以大庆常三减一混合油为原料,产品方案灵活,既能最大量生产优质的低凝柴油,同时生产部分高芳潜的石脑油和低BMCI值的尾油,为大庆石化分公司炼油厂新增经济效益1.5亿元。

Catalyst ZHC-02 is a kind of amorphous co-precipitated hydrocracking catalyst with good hydrogenation activity, strong isomerization activity, high middle distillate selectivity and better diesel low temperature fluidity. It suits for a single-stage or a recycle hydrocracking process with maximum production of low freezing-point diesel. The catalyst was tested in commercial hydrocracking unit with 260 000 tons per year at Daqing petrochemical company refinery on July 1999, with it operating for three years. The results show that catalyst ZHC-02 has a high flexibility of product while processing the blend oil of Daqing atmospheric gas oils and vacuum gas oils. It not only maximally produces low freezing point diesel with excellent quality but also partially produces naphtha with high aromatic potentiality and tail oil with low BMCI value at the same time. It increases economic benefits of 150 million yuan for Daqing petrochemical company refinery.
