The ability of a gamma alumina support to remove nitrogen and sulfur from raw anthracene oil (coal derived liquid) both in the presence and absence of hydrogen treat gas has been measured. This study was conducted in a trickle bed reactor operating at 750�F (399,2�c) and 1500 psig, Iata were obtained at three liquid volume hourly space times: 0.46 hrs.,,0.92 hrs., and 1.84 hrs. The treat gas flow rate was maintained at 1500 scf/bbl. Three experimental runs were made in this study: two with hydrogen treat gas and one with nitrogen treat gas. Also, the effects of presulfiding of an alumina support were assessed.
