Reforming to stabilize the octane number of tower bottom gasoline

Thread Content

This post was last edited by jidsl on 2021-10-25 at 20:00. My unit uses semi-regenerative reforming; subsequently, a benzene extraction unit is used to remove benzene from the gasoline. The products of the reforming reaction proceed to a stabilizer column (butane removal column) via high and low fraction streams, and then to benzene extraction units for the removal of C5 and C6 compounds. The top product of the C6 removal unit serves as the feed for extraction, while the bottom product is benzene-free gasoline that is sent to the gasoline blending tank； There is a question regarding which has a higher octane number, theoretically: the gasoline from the bottom of the stabilizer or the benzene-free gasoline obtained after C6 removal through benzene extraction? I would like to seek advice from the experts here {:1_90:}{:1_90:}
