FIGURE 9 Influences of recycle ratio on group composition of
gasoline

coking gasoline, followed by olefin, naphthene and aromatics. The
content of normal paraffin and isoparaffin decreased by 0.27% and
0.47%, and the content of olefin, naphthene and aromatics increased by
0.28%, 0.30%, and 0.15% with the recycle ratio increment of 0.10.
