Research Advances of Two Desulfurization Technologies for Fluid Catalytic Cracking Gasoline

Due to the strict regulations for environmental protection, it is necessary to adopt effective technologies to reduce gasoline sulfur in fulid catalytic cracking(FCC). At present,technologies of reducing sulfur content of FCC gasoline include FCC raw oil hydrodesulfurization, FCC gasoline hydrodesulfurization, catalytic cracking desulfurization,biodesulfurization and adsorption desulfurization.Among all of these technologies, increasing attention has been focused on the catalytic cracking esulfurization and adsorption desulfurization because of their well prospect .The paper reviews the two methods'research progress and their advantage and disadvantage.
