摘要
以ZSM-5为主体,加入一定量的自制BCM沸石,采用水热合成法合成新型非临氢降凝催化剂。以催化裂化柴油和减一线馏分油为原料对其反应性能进行评价。结果表明,该催化剂具有明显的降凝效果。当反应温度为340℃、空速为1 h-1时,凝点降幅为45℃左右,液体产品收率均在95%以上。所生产的柴油十六烷值高,硫、氮含量低,凝点低,基本满足了产品调合出厂的质量要求。
A non-hydrodewaxing catalyst was prepared by hydrothermal method using ZSM-5 as the main component doped with self-synthesized BCM zeolite. Catalytic behaviors of the catalyst was tested using FCC diesel oil and VGO as the feed. The results showed that the catalyst had remarkable dewaxing effects, with freezing point reduction by 45 ℃ and high liquid yield under reaction temperature of 340 ℃ and LHSV 1 h^-1. Diesel oil produced over the catalyst had higher octane number, low sulfur and nitrogen, and low freezing point, which meet the quality requirements of oil reformulation.
