Abstract-The possibility of using anthracite to produce activated carbon in the form of microporous and
mesoporous anthracite, a cation exchanger, and composite sorption materials was analyzed and the porometric
properties of a variety of sorption materials based on anthracite from the Donets coal basin were studied.
A flowsheet for integrated processing of anthracite to give a set of four products was composed.
The intensive development of sorption techniques
imposes increasingly stringent requirements to such
properties of adsorbents as the sorption capacity deter-
mined by their porous structure, content of surface
functional groups, and service characteristics asso-
ciated with purity, abrasion resistance, and cost .
A promising application field of carbon adsorbents
is storage of gaseous and liquid substances and accum-
ulation of gases, which makes it possible to raise
the sorption capacity of a cylinder with an adsorbent
and enables its use at lower pressures (<35 atm) with-
out any decrease in volume .
Fossil coals used as one of the main raw materials
for production of various carbon adsorbents satisfy
these requirements to a considerable extent .
Among a wide variety of precursors for production
of activated carbons, anthracite is one of the best
suitable raw materials .
An important prerequisite for production of adsorb-
ents from anthracite is that the fine fraction produced
in coal mining is virtually a waste. Moreover, such
grainy starting material does not require any addi-
tional grinding; only a necessary fraction is to be
selected. All these factors make anthracite fines an in-
expensive, readily accessibly, and plentiful raw ma-
terial for manufacture of high-quality highly porous
The attractiveness of this kind of raw materials is
also due to the high content of carbon and low ash
content, as well as to the high mechanical strength
of the final product, activated carbon.
All the above-mentioned application fields of ad-
sorbents predetermine the necessity for integrated
processing of anthracite, which extends the assortment
of inexpensive adsorbents, including composite sorp-
tion materials , which compare well in quality and
service characteristics with industrially manufactured
This study is devoted to a search for ways of in-
tegrated use of highly metamorphized anthracite in
manufacture of sorption materials. Previous publica-
tions describe production of a single type of activated
carbon in anthracite processing [8310, 13]. Here we
made an attempt to process anthracite to obtain an as-
sortment of adsorbents differing in the pore structure
and, consequently, used in different sorption proc-
esses. Conversion of anthracite fines into activated
carbons is a topical task, because this would allow
manufacture of inexpensive mechanically strong ad-
sorbents suitable for a wide variety of applications.
The integrated processing of anthracite into vari-
ous-purpose carbon adsorbents consists in that tech-
nological procedures are carried out successively and
in parallel with the aim of the most complete utiliza-
tion of anthracite.
Integrated use of such a raw material is intimately
associated with the most advanced and economical
form of organization of the chemical process, com-
bined production . A characteristic example of
combining is, in this case, utilization of wastes formed
in the main process to organize additional processing
of anthracite into disperse powders to be used in
manufacture of composite sorption materials .
