ABSTRACT:
A process for saturating benzene in a stream containing hydrocarbons and benzene maintains the benzene saturation reactor in a mixed phase at specific conditions to recover a saturation reactor effluent having a low benzene concentration and a reduced temperature. The benzene saturation reactor operates in a mixed phase without a hydrogen recycle and provides a saturated benzene effluent having less than 2 mol % benzene when operated at an effluent temperature of between 480.degree. F. and 600.degree. F. The discovered temperature range is relatively high and constant for feeds containing a substantial mount of benzene, despite changes in reaction zone pressure and reaction zone liquid LHSV.
