Appeal No. 96-3486
Application No. 08/291,565
final
rejection of claims 1-6 and 8-29, all the claims pending
in
the application. Claims 1, 25, 26, 27 and 28 are
illustrative of the subject matter on appeal and read as
follows:
1. A process for producing a catalyst that contains at
least one refractory inorganic oxide, which is [.alpha]-
alumina, [.gamma]-alumina, [.Delta]-alumina, eta-alumina, theta-
alumina, kappa-alumina, rho-alumina, chi-alumina,
silica, a silica-alumina, a zeolite, a silica-magnesia,
titanium oxide, zirconium oxide, or a mixture thereof;
at least one iron oxide; at least one cerium oxide; at
least one catalytically active metal A from Group VIB,
VIIB, VIII, or IB of the Periodic System; and
optionally at least one compound of metal B from Group
IA, IIA, IVB, or rare earths having atomic numbers 57-
71 inclusive, all deposited in the form of a porous
layer on a ceramic or metal substrate, said process
comprising:
(a) in an atomizing device having an inlet and
an outlet, atomizing an aqueous suspension of
at least one powder of said refractory
inorganic oxide, at least one soluble cerium
salt, at least one soluble iron salt,
optionally at least one portion of at least
one insoluble compound and/or at least one
soluble salt of said metal B, and optionally
at least one portion of at least one metal A
that has been previously deposited by
impregnation of at least one of a precursor
thereof on at least one of the solid
constituents that are present, so as to
recover a powder, and optionally calcining
the resultant powder;
(b) transferring the resultant powder from step
(a) back into suspension while optionally
adding said compound of metal B, as well as,
