摘要:
以新型介孔材料Al-SBA-15与深度改性Y型分子筛复合后得到的微介孔复合分子筛作为主要酸性组分，钨镍为加氢组分，开发了单段高中油型加氢裂化催化剂FC-38，考察了其物化性质、反应性能与工业应用效果，并与FC-34的性能进行了对比。结果表明：壳层Al的引入在不影响分子筛水热稳定性的同时提供了弱酸性位；与单一Y型分子筛相比，Al-SBA-15/Y试样的比表面积和孔体积显著增加，B酸量和L酸量均减少；在相同转化率条件下，与FC-34相比，FC-38的反应温度降低2 ℃以上，中间馏分油选择性提高2.1个百分点，柴油十六烷值增加，尾油芳烃指数降低；在工业装置生产中，催化剂FC-38的活性稳定，加氢裂化产品质量均达到或超过技术协议的指标要求。其中：航空煤油馏分烟点均超过26 mm，可直接作为优质3#航空煤油；加氢裂化尾油可作为优质的润滑油基础油原料或催化裂化原料。
Abstract:
A single-stage high and middle-distillate hydrocracking catalyst FC-38 was developed with micro and mesopore composite zeolite which contained the new mesopore material Al-SBA-15 and deep modified Y zeolite as main acidity component and tungsten and nickel as hydrogenation component. The catalyst′s properties， catalytic performance and industrial application were investigated and were compared with those of FC-34. The result showed that the introduction of shell Al had provided weak acidity without affecting the hydrothermal stability of zeolite. Compared with adopting Y zeolite solely， the Al-SBA-15/Y composite zeolite possessed larger specific surface area and pore volume while containing less B and L acidic sites. Under the same conversion， the reaction temperature of FC-38 catalyst was 2 ℃ lower than that of FC-34 catalyst. The selectivity of middle-distillate of FC-38 catalyst had increased by 2.1 percentage points， the cetane value of diesel oil was higher and the BMCI of tail oil was lower when compared with that of FC-34 catalyst. In industrial units， the activity of catalyst FC-38 was stable and the quality of all hydrocracking products had met/exceeded the requirements of technical agreement. The smoke point of aviation kerosene fraction was more than 26 mm， which could be directly used as high quality 3# aviation kerosene. The hydrocracking tail oil could be used as high quality lubricating base oil raw material or catalytic cracking raw material.
