摘要
介绍了FHUDS-7柴油加氢催化剂开发及工业应用情况。与国外同类型催化剂相比,FHUDS-7催化剂的总酸量和中强酸酸量较小,中强酸酸量降低了30%,但Br nsted(B)酸酸量增加了2.3倍,B酸/Lewis(L)酸增加了3.1倍。FHUDS-7催化剂进行了3500 h稳定性试验,在满足精制柴油硫质量分数小于10μg/g的条件下,催化剂脱硫活性无明显降低,平均反应温度仅提高3℃,提温速率为0.6℃/月,FHUDS-7催化剂体现了良好的活性和稳定性。工业应用结果表明:该催化剂体系可以在高空速条件下加工直馏柴油或二次加工混合油,满足生产国Ⅵ标准的超低硫柴油要求。催化剂的失活速率为0.6~0.7℃/月,是国外催化剂失活速率的一半,可以有效延长装置运行周期。该催化剂体系体现了优异的超深度加氢脱硫活性和稳定性,是长周期生产国Ⅵ标准柴油的理想催化剂。
The development and industrial application of FHUDS-7 diesel hydrogenation catalyst were introduced.Compared with the same type of catalyst abroad,the amount of total acid and moderately strong acid of FHUDS-7 catalyst were smaller,and the amount of moderately strong acid of FHUDS-7 catalyst decreased by 30%.However,the amount of B acid and the ratio of B acid/L acid of FHUDS-7 catalyst increased by 2.3 and 3.1 times,respectively.The HDS activity of FHUDS-7 catalyst was tested by 3500 hours for producing the ultra-low sulfur diesel fuel with the sulfur content less than 10℃/g.The average reaction temperature was only increased by 3℃and the deactivation rate was 0.6℃/month,indicating that FHUDS-7 catalyst showed good activity and stability.The industrial application results showed that the catalyst system can produce the GuoⅥstandard ultra-low sulfur diesel fuel,as raw oil was the straight run diesel oil or secondary processing mixed oil at high space velocity.The deactivation rate of the catalyst was 0.6~0.7℃/month,which was half of the deactivation rate of foreign catalyst.FHUDS-7 catalyst could effectively extend the operation period of the unit and showed excellent HDS activity and stability,which was an ideal catalyst for long-term production of GuoⅥstandard diesel oil.
