摘要

Studies at 375 exp 0 C and 6.9 MPa revealed complex interactions between H sub 2 O and H sub 2 S which significantly affect the rate of overall hydrodenitrogenation. In the absence of H sub 2 S, addition of H sub 2 O (generated in situ from decanol) produces an increase in the overall HDN rate that is rapidly reversible. When H sub 2 S is present, a comparable increase in overall rate is observed upon the addition of H sub 2 O; however, most of this increase is maintained for a long period after the H sub 2 O is removed. A standard resulfiding procedure reduces the catalyst activity to the level it had before addition of water. (ERA citation 08:038347)
