文摘By using the group IIIB or groupVIIB metals and modulating thecharacteristics of electric charges on carrier surface, improving the catalyst preparation processand techniques for loading the active metal components, a novel type SY-2 catalyst earmarked fortwo-stage hydrogenation of pyrolysis gasoline has been developed. The catalyst evaluation resultshave indicated that the novel catalyst is characterized by a better hydrogenation reaction activityto give higher aromatic yield.
