中海油惠州炼化高压加氢裂化装置处理能力为4000kt/a,采用先进的壳牌专利工艺技术,是目前国内单套处理能力最大的加氢裂化装置,加工原料主要是常减压减二、减三线蜡油和焦化蜡油。该装置选用标准催化剂公司开发的保护剂Opti Trap[Medellion]、Opti Trap[Macro Ring]、Opti Trap[Ring]、Opti Trap[Filter Lobe]、Max Trap[Ni,V]VGO、加氢精制催化剂DN-3551、深度脱氮催化剂Z-503和加氢裂化催化剂Z-3723。从催化剂床层压降、反应温度(催化剂活性)、催化剂选择性、产品收率和产品性质等方面分析催化剂使用性能,结果表明:保护剂较强的容垢能力和级配装填技术,为主催化剂充分发挥性能提供了条件;加氢精制催化剂DN-3551以及深度脱氮催化剂Z-503具有较强的脱硫、脱氮和芳烃饱和能力;加氢裂化催化剂Z-3723具有较高的裂化活性和选择性。
CNOOC Huizhou refinery high pressure hydrocracking unit processing capacity of 4000kt / a, the use of advanced patented Shell technology is currently the single set of processing capacity of the largest hydrocracking unit, the processing of raw materials is mainly atmospheric decompression by two, minus three lines Wax and coker oil. The device uses Opti Trap [Medellion], Opti Trap [Macro Ring], Opti Trap [Ring], Opti Trap [Filter Lobe], Max Trap [Ni, V] VGO, Hydrotreating Catalyst DN -3551, deep denitrification catalyst Z-503 and hydrocracking catalyst Z-3723. The catalyst performance was analyzed from the pressure drop of the catalyst bed, the reaction temperature (catalyst activity), catalyst selectivity, product yield and product properties. The results showed that: Catalyst DN-3551 and deep denitrification catalyst Z-503 have strong ability of desulfurization, denitrification and aromatic saturation; hydrocracking catalyst Z-3723 has higher cracking activity and Selective.
