Abstract
A mild hydroconversion process for petroleum cuts using a catalyst comprising at least one matrix, at least one Y zeolite with a lattice parameter which is in the range 24.15 .ANG. to 24.38 .ANG. (1 nm--10 .ANG.), at least one Y zeolite with a lattice parameter of more than 24.38 .ANG. and less than or equal to 24.51 .ANG., and at least one hydro-dehydrogenating element.
