摘要：Hydrogenation of phenanthrene (PHE HYD) was investigated over a commercial NiW/Al2O3 catalyst under practical reaction conditions. GC-MS analysis was utilized to identify the numerous products formed during PHE HYD. The products included dihydrophenanthrene (DHP), 1,2,3,4-tetrahydrophenanthrene (THP), sym-octahydrophenanthrene (1,8-OHP), asym-octahydrophenanthrene (1,10-OHP) and perhydrophenanthrene (PHP), but the cracking products were not found under the reaction conditions. The effects of operating conditions such as temperature, pressure and H-2/liquor on PHE HYD were tested in detail. It is found that temperature and pressure had remarkable effect on PHE HYD, but volume ratio of H-2/liquor had little effect on PHE HYD at the observation range. The addition of decalin had a positive impact on PHE HYD; it could increase the conversion of PHE and the selectivity to PHP.
