Abstract:
1. A catalyst comprising at least one support, at least one group VIII element, at least one group VIB element and phosphorus, in which the density of group VIB elements per unit surface area of the support is in the range of (limits included) 2×10 −4 to 18×10 −4 grams of oxides of group VIB elements per m 2 of support, in which the molar ratio of phosphorus to the group VIB element is in the range of 0.27 to 2.00, and in which the amount of group VIB elements is in the range of (limits included) 1% to 20% by weight of oxides of group VIB elements and in which the support has a specific surface area of less than 135 m 2 /g, and in which the phosphorus content is in the range of (limits included) 0.1% to 10% by weight of P 2 O 5 .
