the acidic material, with adsorption of at least some part of the
reaction products on the acidic material (Brief, pages 2-3).
Illustrative independent claim 12 is reproduced below:
12. A process for the removal of carbonyl compounds
from hydrocarbons comprising feeding a hydrocarbon stream
containing less than 0.1 weight percent carbonyl compounds
comprising at least aldehydes or ketones through a bed of
particulate acidic material at a temperature in the range of 100 to
400/C under conditions of pressure and residence time to result in
reaction of said carbonyl compounds to produce reaction products
and the deposition of said reaction products on said acidic
material.
The examiner has relied upon the following references as
evidence to support the rejections on appeal:
Holiday 3,453,343 July 1, 1969
Hupp et al. (Hupp) 4,117,021 Sep. 26, 1978
The claims on appeal stand rejected under 35 U.S.C. § 102(b)
as anticipated by or, in the alternative, under 35 U.S.C. § 103(a)
as unpatentable over Hupp (Answer, page 3). Claims 12 and 14 stand
rejected under 35 U.S.C. § 103(a) as unpatentable over Holiday
(Answer, page 4). We reverse the examiner’s rejections on appeal
essentially for the reasons stated in the Brief and Reply Brief, as
well as the reasons set forth below.
