Abstract The catalyst regenerating process is a two-step one. In the first step of reducing catalyst, S reacted with active metal is converted into H2S to escape; and in the second step, the catalyst is oxidized and coke eliminated. The regeneration process can reduce greatly the formation of SO4(-2) on catalyst and this is favorable to the activity of catalyst and can reduce the corrosion of equipment.
