Abstract: The fluid catalytic cracking(FCC) is the principal
gasoline-producing process in the refinery. Considerable amounts of harmful
sulfur oxides and nitrogen oxides (SO_x and NO_x ) are generated with the FCC
operation. Impacted by strengthening environmental regulations and the current
global emphasis on environmental protection and pollution abatement, refiners
have been meaning to look for effective ways to control and reduce SO_x and
NO_x emissions. FCC DeSO_x and DeNO_x additives is the most promising measure.
The present paper reviews the developments in FCC DeSO_x and DeNO_x additive
technology based on the respective authors' works, the future directions of the
technology are also discussed.
