| 中文摘要 |
| 论述了石油流化催化裂化烟气中H2S气体的选择性催化氧化处理工艺和工艺中所使用的各种类型选择性氧化催化剂.目前已发展并投入使用的选择性氧化工艺主要有:Superclaus工艺、Euroclaus工艺、Clinsulf-Do工艺、BSR/Hi-Activity工艺、Selectox工艺和Modop工艺等,各工艺具有不同的特点和应用范围.H2S选择氧化催化剂主要包括以下几种体系:碳体系、SiC载体体系、分子筛体系、氧化物体系和柱撑黏土体系等.其中碳体系和氧化物体系的研究开展的较早较多,关于分子筛体系的研究近期有所减少,SiC是研究人员认为非常有潜力的一个载体体系,其相关体系研究也一直在进行之中,柱撑黏土体系还处于初步研究阶段,离实际应用尚有距离. |
| 英文摘要 |
| This review summarizes and discusses different selective catalytic oxidation technologies and various catalysts for removing H2S, the undesirable byproduct of the fluid catalytic cracking(FCC)processing. Currently the selective oxidation technologies used include Superclaus, Euroclaus, Clinsulf-Do, BSR/Hi-Activity, Selectox and Modop techniques, which have various characteristics and application areas. Catalysts for H2S selective oxidation mainly contain the following systems: carbon, supported SiC, zeolite, oxide, and pillared clay. Former studies focused on carbon and oxide systems. The research interest on zeolite system decreased in recent years, while SiC is regarded as a typical support with great potential for this reaction and continues to be attractive. Pillared clay system is at the preliminary research stage, and is still far from practical application. |
