Abstract—Plasma based technology for producing active carbon is proposed.
In the modern world there is clear tendency to
organization of ecologically pure industrial production.
This is connected with the general view that catastrophic
and practically throughout environment pollution is a real
fact . The main sources of pollution are industrial and
domestic effluences containing petroleum products, oil,
phenols, pesticides, herbicides, heavy metals and a scope
of organic chemicals. All these substances are potential
hazards for people and live nature. A significant amount
of pollutions is produced by energetic enterprises, the
power station using coil in particular. The more and more
rigid restrictions concerning various hazardous effluences
are issued, and they require development and application
of new and more effective materials and technologies
providing ecological safety of operation of power
Among the known methods of purification water, its
deep purification to any degree of purity provides sorption
purification only. This method is based on the application
of sorbents, active carbon predominantly .
The principal restriction to application of carbons
sorbents for energetic ecology is high cost and deficient
due to disadvantage of currently used technology. The
known technologies of producing carbon sorbents (from
coil, wood, nut crust and other) use energy of fuel
combustion or electric heating [3, 4]. Alternatively, for
producing active carbon by existing methods can be
applied energy of low temperature plasma. The low
temperature plasma increases considerably efficiency of
processing solid fuel and intensifies the process of
production of active carbon owing to presence in the
plasma of active radicals, ions, electrons, and due to its
significant temperature and high specific power .
Thus, investigations directed to the study and
development of plasma technology for producing
sorbents are actual and can result in development of
technology for producing active carbon of any type with
lower energy consuming.
For the studying processes of plasma pyrolysis and
gasification of carbon using electric arc reactor as
a generator of low temperature plasma we created an
experimental installation (Fig. 1), consisting of the
following principal nodes: system of electric feeding,
combined type electric arc reactor, direct current
electromagnetic coil, vapor generator, system of feeding
with carbon and air, system for gas output, cooling and
purification, control console, muffle chambers with
connecting pipes for gas reagents, separation chambers
and chambers for pyrolysis and activation.
During the experiment the active carbon samples from
pyrolysis and activation chamber are investigated on
sorption activity on iodine, benzene, methylene blue and
iron and compared with currently used sorbents (birch
active carbon BAC).
In the process of experiments material and heat flows
were registered in all nodes of installation. In part, were
registered consuming of carbon, vapor, air, graphite
electrodes, active carbon, dust and sublimates, and
electric power of reactor, heat power, heat loss in plasma
reactorm muffle chambers and gas outlet.
Initially, the experiment was conducted in the absence
of air and vapor. In the course of experiment the grinded
