bc is surprised, so we are left w/ the rare instance of charcoal briquettes, coke, etc.
bc also surprised the best (only?) coke is from bituminous not anthracite.
p.s. from the article Jack referenced below:
------------
COAL is not a hydrocarbon. Even if we leave out of
consideration the technically very important constituents ash, moisture, sulfur, and nitrogen, the
data in Table I show that, in a high-rank bituminous coal,
there may be one to nine oxygen atoms to every hundred
atoms comprising the coal substance.
----------------
It's a matter of definition -- coal is a sugar!, partially carbonized along w/ lignin and cellulose. Which makes sense since that's from whence it came.

which gives, for anthracite (by weight)
78 \pm 12% C and 20 \pm 12% H. Since the atomic weight of carbon
is 12 and that of H is 1 (the H is combined in compounds), there is about
one hydrogen atom available for each 7, or so, carbon atoms.
Burning of coal, therefore, is not a simple process of combining
carbon with oxygen.
