FCC DeSO_x and DeNO_x additive technology

摘要

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.
