摘要
介绍针对催化裂化(FCC)汽油清洁化开发的深度加氢脱硫和烯烃定向转化相耦合的FCC汽油加氢改质GARDES技术的工艺配置、催化剂的设计理念、工业试验情况及满足国Ⅳ排放标准兼顾满足国Ⅴ排放标准的清洁汽油的中试评价情况。工业试验标定结果表明:所得产品可作为满足国Ⅳ排放标准的清洁汽油调合组分,在烯烃体积分数降低16百分点的情况下,辛烷值损失为1.0个单位。对于不同硫含量FCC汽油的中试评价结果表明:在目标产品为满足国Ⅳ排放标准要求的清洁汽油调合组分时,脱硫率为69%～89%、辛烷值损失为0.3～0.5个单位;在目标产品为满足国Ⅴ排放标准要求的清洁汽油调合组分时,脱硫率为88%～96%、辛烷值损失为0.7～0.9个单位。
With the aim of producing clean gasoline from fluid catalytic cracking（FCC） naphtha with higher sulfur and olefin contents,a GARDES technology for hydro-upgrading FCC naphtha was developed by coupling the deep desulfurization and directed olefin conversion.This article introduced the process configuration,catalyst design,and industrial results of the GARDES technology and then presented some pilot-plant results for producing clean gasoline fraction that meets the China Ⅳ and Ⅴ standards.The industrial results show that the hydro-upgraded naphtha can be used as a blend component for the China Ⅳ gasoline pool with olefin reduction of 16% and RON loss1 unit.The pilot plant evaluation demonstrate that at HDS of 69%—89%,the product can be used as a blend component for the China Ⅳ gasoline pool with RON loss of 0.3—0.5;while at HDS of 88%—96%,the product can be used as a blend component for the China Ⅴ gasoline pool with RON loss of 0.7—0.9.
