摘　　要：总结了国内外用于催化裂化装置的具有降低催化裂化汽油硫含量作用的助剂及其材料的研究状况。重点介绍了目前催化裂化过程中使用的降硫助剂的脱硫率及其对催化裂化产品分布的影响等。同时指出,采用高效降硫材料直接添加于催化裂化装置,既不影响裂化产品分布和质量,又能有效地降低催化裂化汽油硫含量,是未来降低汽油硫含量的一个有效途径。Research of the sulfur transfer catalysts and materials which can be used in FCC unit to reduce sulfur in FCC naphtha is described. The sulfur removal rate of the assistant catalysts applied in domestic FCC units and their impact on product slates are highlighted. It is proved in operation that the direct addition of sul- fur transfer catalyst into FCC unit can effectively reduce sulfur in FCC naphtha without any negative impact on product distribution and product specifications. It is one of effective approaches to reduce sulfur in naphtha in future FCC unit operation.
