Bearden discloses catalysts useful in processes for
hydroconverting carbonaceous materials such as
hydrocarbonaceous oils and coal (column 1, lines 10 through
13). The catalyst is prepared by a process which comprises
(a) adding a water soluble polyhydroxy compound to an aqueous
solution of chromic acid (CrO ); (b) forming a mixture of a
3
hydrocarbon material and at least a portion of the mixture
from step (a); and, (c) heating the mixture resulting from
step (b) in the presence of a hydrogen sulfide-containing gas
to produce a slurry comprising said hydrocarbon material and a
solid chromium-containing catalyst (column 1, lines 50 through
64). Useful water soluble polyhydroxy compounds include
sucrose (column 2, lines 13 through 22). The
