Technology Progress of Desulfurization of FCC Gasoline

With the increase of motors in the city,motor exhaustion has been the main pollution of atmosphere in the city.Especially,SO_X and NO_X do harm to environment.For making the atmosphere quality better,sulfur content of gasoline product must be reduced.FCC gasoline is important component of gasoline product,whose sulfur content influences sulfur content of gasoline product directly.At present,means of reducing sulfur content of FCC gasoline include FCC Gasoline hydrodesulfurization,solvent extraction desulfurization,catalytic cracking desulfurization,oxidative desulfurization,biodesulfurization,and adsorption desulfurization.Domestic and foreign development of means of each desulfurization is outlined.
