焦化蜡油加氢处理-催化裂化联合技术的开发

INTEGRATION OF CGO HYDROTREATMENT WITH FCC

采用脱氮活性高的ＲＮ－２催化剂对管输油的焦化蜡油进行加氢处理，脱除其中的氮、硫等杂质及改善烃类组成后，进行催化裂化或与直馏蜡油混合作催化裂化进料。工业应用结果表明，当掺炼１６％加氢焦化蜡油后，可提高汽油产率２个百分点并降低了１个百分点油浆产率。

CGO were hydrotreated by RN 2 catalyst to remove N and S impurities and improve the quality. The hydrotreated CGO was proposed to be mixed with VGO as FCC feedstock after testing in the pilot plant. The commercial results indicated that the gasoline yield increasd by 2% and slurry decreased by 1% when 16% hydrotreated CGO was mixed with VGO as feedstock in comparison with the unhydrotreated CGO and VGO mixture.
