Abstract: The end point of C9+ distillates at the xylene tower bottom of the1800k/a continuous catalytic reforming unit in SINOPEC Qingdao Petrochemical Company was about 250 ℃, resulting in overstandard end point of naphtha. To solve the problems, a vapor-phase stream side-draw pipe was added to the xylene tower. The vapor-phase stream was used as a fraction of gasoline blending component directly. The bottom fraction of the tower was used as a fraction of the diesel oil blending. The results indicate that the measures can effectively remove the heavy components in C9+ fraction and reduce the end point of the naphtha.
