Abstract
The invention concerns a catalyst comprising: PA0 (a) a carrier containing at least 20% by weight of a fluorinated bridged clay of the smectite group, PA0 (b) an amorphous matrix containing at least 10% by weight of alumina, and PA0 (c) at least one group VIII metal or metal compound or an association of at least one group VI B metal or metal compound with at least one metal or compound of a metal selected from group VIII non-noble metal. The metals amount, calculated as oxide(s), in proportion to the final catalyst weight, is from 0.01 to 5% for the group VIII noble metals, from 0.01 to 20% for group VIII non-noble metals and from 5 to 40% for the association of group VI B metals with group VII non-noble metals. The carrier amount is such that the florinated bridged clay content of the final catalyst is at least 12% by weight; the matrix amount forms the complement to 100% by weight of the catalyst. The catalysts according to the invention can be used for mild hydrocracking operations having as an object improving the viscosity of the lubricating oils and hydrocracking of heavy oil cuts so as to obtain middle distillates: kerosene and gas oils
