摘要: 以改性分子筛和氧化铝为载体,采用一次浸渍法负载W、Ni金属组分,制备了高活性加氢改质催化剂。该催化剂具有孔体积大、比表面积大、孔分布集中、金属分布均匀等特点。催化剂性能评价试验结果表明,该催化剂用于处理催化裂化柴油,能大幅提高十六烷值,且具有脱硫活性高、稳定性好等特点。

Abstract: A high activity hydro-upgrading catalyst was prepared using modified zeolite and alumina as carrier and loading W, Ni metal components by impregnation method. The catalyst had the characteristics of large pore volume, high specific surface area, concentrated pore size distribution and uniform metals dispersion. Test results of catalytic performance evaluation showed that during the hydroupgrading of FCC diesel fraction, said catalyst exhibited good desulfurization and denitrogenation activity and stability, the cetane number of the treated FCC diesel fraction increased significantly.
