Appeal No. 94-1863
Application 07/832,154
second, sixth, and eighth secondary group of the Periodic System
of Elements," because the disclosure at page 2, lines 32 to 35,
reads at least two other oxides. In our view, appellants'
disclosure would reasonably convey to those skilled in the art
that the language at least two other oxides would include at
least three oxides as now recited in claim 1, notwithstanding the
fact that the examples only show catalysts containing three metal
oxides. In this regard, we note the disclosure at page 3, lines
17 to 27, which reads as follows:
Preferred metal oxides are the oxides of Cu, Zn,
Cr, Mo, W, Fe, Co and Ni.
In one preferred embodiment of the invention, the
inorganic support is impregnated with each of the
metal oxides in a quantity of from about 0.05 to
about 4% by weight and more preferably from about 0.1
to about 2% by weight, based on the quantity of
support material.
A particularly preferred catalyst is made up of
an aluminum oxide support impregnated with at least
three of the following oxides: copper oxide, iron
oxide, molybdenum oxide, chromium oxide and zinc
oxide.
Certainly, this portion of the disclosure would clearly convey to
those skilled in the art that all eight, or preferably at least
three, metal oxides without any restrictions as to their combination
can be impregnated in the inorganic support. Thus, appellants'
