摘要：
PURPOSE: To obtain an efficient desulfurizing method for a catalytic cracking gasoline whereby the decrease in olefin content is inhibited and the decrease in octane number is inhibited as much as possible. CONSTITUTION: A fraction contg. a high amt. of hardly removable sulfur compds. and/or a fraction contg. a high amt. of easily removable sulfur compds. is separated from a catalystic cracking gasoline; then at least either of the two fractions is hydrodesulfurized; and they are mixed again.
