摘要
为了全面考察FC-20新一代多产低凝柴油加氢裂化催化剂的催化性能,在200 mL加氢裂化装置上,使用不同原料油,在不同压力、不同转化深度和不同柴油改质方案下进行了加氢裂化或改质试验研究。结果表明,FC-20催化剂在不同工艺条件下均显示出适宜的裂化活性、很高的加氢异构性能、良好的温度敏感性、较强的优先裂解或异构蜡组分的能力、良好的生产操作灵活性和广泛的原料油适应性,可用于生产优质化工用石脑油、合格的3号喷气燃料、低凝清洁柴油以及低倾点润滑油基础油等产品。工业应用结果表明,FC-20催化剂可以在较低压力下提高劣质柴油的品质,并大幅度改善柴油的低温流动性。
To well understand the new generation hydrocracking catalyst FC-20 with high selectivity＆amp;nbsp;of middle distillates,the tests in pilot plant were conducted using several kinds of feedstocks under dif-ferent pressures,different conversion depths with different diesel upgrading scheme. The test results show that the catalyst FC-20 is characterized by suitable cracking activity,high hydroisomerization ac-tivity,good temperature sensitivity and strong ability to preferentially crack and isomerize wax compo-nents in feed. The catalyst also has a good flexibility to product scheme and wide adaptability to feeds, which could be used to produce premium chemical naphtha,No. 3 jet fuel,clean diesel with low solidifi-cation and high cetane number,and low pour point lube base oil feed. The results of commercial applica-tion indicate that catalyst FC-20 can upgrade the poor quality diesel and improve the low temperature fluid performance.
