FF-20加氢裂化预处理催化剂的研制

FF-20催化剂是FRIPP研制的新型高活性加氢裂化预处理催化剂。该催化剂以改性氧化铝为载体，采用一次浸渍法担载W、Mo、Ni金属组分，具有孔容大、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：该催化剂用于加工处理国内外典型高硫蜡油，具有加氢脱硫脱氮活性高、芳烃加氢饱和能力强、稳定性好等特点，是一种性价比较高的馏分油加氢处理催化剂。

RESEARCH AND DEVELOPMENT OF FF-20 CATALYST FOR PRE-TREATING HYDROCRACKING FEEDSTOCKS

FF-20 catalyst is a high activity hydrocracking pre-treating catalyst newly developed by FRIPP. Modified alumina is used as catalyst carrier and W-Mo-Ni are used as hydrogenation components. The catalyst is prepared by a one-step impregnation method. FF-20 catalyst is characterized by large pore volume, high surface area, narrow pore size distribution and uniform metal dispersion. Evaluation results show that FF-20 catalyst is suitable for processing high sulfur feed and it exhibits high HDS activity, high HDN activity, good aromatics-saturation and stability. Since the Mo content in the catalyst is low, said catalyst is a low cost high performance hydrotreating catalyst.
