and with a chemical composition, expressed as the anhydrous compound, in terms
of moles of oxide:
(XO2):(Y2O3)m:(Z2/nO)p
in which:
X represents at least one tetravalent element selected from the group formed
by Si, Ge; Y represents at least one trivalent element selected from Al, B, Cr,
Ga; Z represents at least one cation with valency n;
and in which:
n is in the range 2 to 4, m is in the range 0 to 0.2, preferably in the
range 0 to 0.05, and p is in the range 0 to 0.2, preferably in the range 0 to 0.05.
The invention also concerns a hydrocracking/hydroconversion process and a hydrorefining
process employing said solid in the catalyst composition.
