Abstract:
The catalytic activity of two high loaded nickel-based catalysts was evaluation in a continuously operated trickle bed reactor. The conversion of model substances was evaluated with and without the presence of sulfur in the feedstock. Both catalysts were active for more than 48h of time on stream without reduction of activity by the addition of sulfur to the feedstock while the selectivity was affected. Formation of Ni3S2 was observed in both catalysts. Overall, both catalysts were active over the reaction time tested, although it was assumed that the hydrogenation capacity is reduced by sulfur poisoning.
