Appeal No. 1997-1536
Application 08/342,817
The claimed invention is directed a process for preparing
a carbonaceous char from bituminous coal or a bituminous
material wherein a carbonized and oxidized bituminous coal or
bituminous material is contacted with a nitrogen-containing
material such as urea and at least one of sucrose or fructose
and contacting the nitrogen and sucrose or fructose treated
material at a temperature above 700EC to provide a
carbonaceous char. According to appellants, the carbonaceous
char so-produced possesses catalytic activity.
Claims 1 and 10 are believed to be adequately
representative of the appealed subject matter and are
reproduced below for a more facile understanding of
appellants' invention.
Claim 1. A process for the manufacture of a carbonaceous
char which comprises the steps of:
a. carbonizing a bituminous coal or a bituminous
material at temperatures below 700EC;
b. oxidizing said carbonized bituminous coal
or bituminous material at temperatures below 700EC during
or after said carbonization,
c. contacting the carbonized and oxidized
