Abstract
We studied the effect of the H2S and the H-2 partial pressures on the competitive HDN of aniline and indole over a NiMoP-gamma Al2O3 catalyst. The reactions were carried out with a continuous-flow reactor at 5 MPa and 573 K. Our results confirm that H2S has a promoting effect on the C-N bond cleavage and a detrimental effect on hydrogenation but, in contrast to what is reported in the literature, we found that the global effect of H2S on nitrogen removal is negative. We explained this difference by the fact that, in our experiments, HDN is controlled by the hydrogenation function of the catalysts. H-2 has an effect opposite to H2S and the parameter that can be considered is the ratio H2S/H-2.
