摘　　要：中国石化大连石油化工研究院(DRIPP)开发了以核壳型Al-SBA-15/Y复合分子筛为主要裂化组分,W-Ni为加氢组分的新一代单段高中油型加氢裂化催化剂FC-38。Al-SBA-15/Y复合分子筛将介孔SBA-15材料与改性Y分子筛进行复合,兼具微孔和介孔分子筛优势,既保证了裂化反应所需的酸性位,又提供了通畅的介孔通道,有效提升了催化剂的性能。结果表明,催化剂在首次工业应用周期内,活性稳定,各馏分产品质量均达到/超过炼厂要求,航煤馏分可直接作为优质3#喷气燃料,尾油粘度指数较上一周期提高6~7个单位,芳烃指数(BMCI)值也显著低于上周期,可作为优质的润滑油基础油原料或催化裂化原料。FC-38催化剂为炼厂提质增效提供有效助力。DRIPP developed a new generation single-stage high and medium oil hydrocracking FC-38 catalyst with core shell Al-SBA-15/Y composite zeolite as the main cracking component and W-Ni as the hydrogenation component.Al SBA-15/Y composite zeolite combines mesoporous SBA-15 material with modified Y zeolite,which has the advantages of microporous and mesoporous zeolite.It not only ensures the acid site required for cracking reaction,but also provides a smooth mesoporous channel,which effectively improves the performance of the catalyst.The industrial application results of FC-38 show that in the first industrial application cycle,the activity of the catalyst is stable,and the product quality of each fraction meets/exceeds the requirements of the refinery.The aviation coal fraction can be directly used as high-quali⁃ty 3#jet fuel.The viscosity index of tail oil is 6~7 units higher than that in the previous cycle,and the BMCI value is also significantly lower than that in the previous cycle.It can be used as high-quality lube base oil raw material or catalytic cracking raw material.FC-38 catalyst provide effective assistance for refinery to improve quality and efficiency.
