The production of activated carbon from a bituminous coal

2020-7-16 · The coal sample was ground to pass a 10-mesh U.S. standard size (i.e. particle diameter less than 2 mm) before it was devolatilized. Sieve analysis showed that about 93% of the coal sample had a particle diameter less than 1000 micron and larger than 75 micron. Elemental and proximate analyses of the coal sample are listed in Table 1.
