催化裂化原料预处理催化剂FF-18的性能和应用

PERFORMANCES AND APPLICATION OF FF-18 CATALYST FOR FCC FEEDSTOCK PRETREATING

介绍了催化裂化原料加氢预处理催化剂FF-18的反应性能评价及首次工业应用情况。该催化剂采用镍和钨作为活性金属组分。评价中采用了硫质量分数约1．5%的伊朗VGO,工业应用中采用了硫质量分数约2．0%的由VGO,CGO和DAO混合成的混合油,评价和工业应用表明,FF-18催化剂具有较好的加氢脱硫性能及原料适应性,加氢处理得到的蜡油是优质催化裂化原料。

The performances evaluation and first commercial application of FF-18 catalysts for FCC feed- stock hydrotreating are described. The catalyst, with nickel （Ni） and tungsten （W） as active components has been evaluated by the laboratory tests with Iranian VGO as feedstock containing 1.5 m% of sulfur and by commercial application with mixed VGO, CGO and DAO as feedstock containing 2.0 m% sulfur. In both the tests and commercial operation, the FF-18 catalyst has exhibited a good desulfurization performance and strong adaptability to different feedstocks. The hydrotreated VGO is excellent feedstock of FCCU.
