Appeal 96-0460
Application 08/150,303
B. Discussion
1. Scope and meaning of claim 1
A specification may define terms used in a claim. When
the definition of "a Group IVB metal oxide modified with an
oxyanion of a Group VIB metal" set out in the specification is
given weight, as it should, then the scope and meaning of
claim 1 becomes the following:
A process for hydrocracking naphtha, said process
comprising contacting a naphtha feed with a hydrocracking
catalyst under sufficient hydrocracking conditions, said
hydrocracking catalyst comprising
(1) a hydrogenation/dehydrogenation catalytic
component and
(2) an acidic solid catalytic component
comprising a Group IVB metal oxide modified with an
oxyanion of a Group VIB metal, which is a material
comprising,
(a) by elemental analysis, a Group IVB
metal, a Group VIB metal and oxygen,
(b) with more acidity than a simple
mixture of separately formed Group IVB metal oxide mixed
with a separately formed Group VIB metal oxide or
oxyanion.
