Appeal No. 94-1863
Application 07/832,154
The subject matter on appeal is directed to a catalyst for
removing sulfur compounds from industrial gases and to a process
for the production of the catalyst. The catalyst consists
essentially of an inorganic, abrasion-resistant and non-
combustible support which is uniformly impregnated with a mixture
of (1) at least one oxide of an element selected from the sixth
secondary group of the Periodic System of Elements and (2) at
least three other oxides of elements selected from the first,
second, sixth, and eighth secondary group of the Periodic System
of Elements.
In their brief, appellants state that none of the claims
will be argued separately. Accordingly, all the claims are
considered to stand or fall with claim 1, the only independent
claim, which reads as follows:
1. A catalyst for removing sulfur compounds from industrial
gases consisting essentially of an inorganic, abrasion resistant
and non-combustible support uniformly impregnated with a mixture
of at least one oxide of an element selected from the sixth
secondary group of metals of the Periodic System of Elements and
at least three other oxides of elements selected from the first,
second, sixth and eighth secondary groups of metals of the
Periodic System of Elements.
