Abstract:
A catalytic composition useful in the catalytic-cracking of hydrocarbons containing vanadium as a contaminant, the composition comprising:a zeolite as matrix, andan agent causing inactivation of the vanadium, wherein said agent comprises a compound having a formula selected from the group consisting of M(PO.sub.3).sub.2, M.sub.2 (P.sub.2 O.sub.7), M.sub.3 (PO.sub.4).sub.2, M.sub.10 (OH).sub.2 (PO.sub.4).sub.6, M(H.sub.2 PO.sub.4).sub.2, MHPO.sub.4, 3M.sub.3 (PO.sub.4).sub.2. MCO.sub.3, M(H.sub.2 PO.sub.2).sub.2, MHPO.sub.3, M(PO.sub.2).sub.2, M.sub.2 P.sub.2 O.sub.6, and A(PO.sub.3).sub.3,wherein M stands for a cation of a bivalent metal selected from the group consisting of Be, Mg, Ca, Sr, Ba, Zn, Cd and Pb, andA stands for a cation of a trivalent metal selected from the group consisting of Al, Ga, In, As, Sb, Bi, La, Ce, Pr, Nd, Pm, Sm, Eu, and Gd, andwherein the vanadium is stabilized as at least one compound containing vanadium in V(IV) or V(V) oxidation states.
