摘要
分别以介孔-微孔复合分子筛MCM-41/Beta和AlSBA-15/HY为载体,Ni-W为活性组分,制得两种负载型催化剂,以减压蜡油为原料考察了两种催化剂的加氢裂化性能。结果表明,NiW/MCM-41/Beta和NiW/AlSBA-15/HY都具有很高的加氢裂化活性,此外,NiW/AlSBA-15/HY还具有中间馏分油选择性高及目的产品质量优的特点,能够满足加氢裂化装置最大量生产中间馏分油的要求。
Two hydrocracking catalysts were prepared using MCM-41/Beta and AlSBA-15/HY Micro/ Mesopore composite molecular sieves as supports and Ni-W as active component,and their hydrocracking performances were investigated with vacuum gas oil(VGO) as feedstock.The results indicated that NiW/MCM- 41/Beta and NiW/AlSBA-15/HY catalysts had high hydrocracking activity.Moreover,NiW/AlSBA-15/HY catalyst had higher middle distillates selectivity and excellent objective products,which met the requirement for maximum middle...
