Abstract — Activated carbons are used in industries for
various applications like gold extraction, water and air
purification, electrolyte cleaning, medical waste
treatment, textile, cooking industries and so on. Mostly
activated carbons are produced from coconut shell.
These activated carbon preparing setup are
comparatively very larger in size and capacity.In order
to overcome this difficulty, we have fabricated an
experimental prototype of manufacturing activated
carbon with deformation and temperature analysis, at
low cost and compact in size.
Keywords—activated carbon, experimental setup of
manufacturing activated carbon, pyrolysis analysis.
I. INTRODUCTION
Activated carbon includes a wide range of amorphous
carbon-based materials prepared to exhibit a high
degree of porosity and an extended inter- particulate
surface area. It is also a common term used for a group
of adsorbing substances of crystalline form, having large
developed internal pore structures that make the carbon
more adsorbent.
There are many recipes for the proportion of
clay, but they all strike different balances between mold
ability, surface finish, and ability of the hot molten metal
to degas.
In wastewater treatment, activated carbon is
usually used as a filter medium in tertiary (later)
treatment processes. In addition to its drinking water
and wastewater treatment applications, activated
carbon is used today for many other purposes. Some
other common uses are corn and cane sugar refining,
gas adsorption, dry cleaning recovery processes,
pharmaceuticals, fat and oil removal, electroplating,
alcoholic beverage production, and as nuclear power
plant containment systems.
II. LITERATURE REVIEW
Mohammad Khah A., et al., (2009) [1], proposed that
adsorption is a widely used as an effective physical
method of separation in order to elimination or lowering
the concentration of wide range of dissolved pollutants
(organics, inorganic) in an effluent. It is big news that
activated carbon is a well-known adsorbent that can be
used efficiently for removal of a broad spectrum of
pollutants from air, soil and liquids. Adsorbents are
usually porous solids, and adsorption occurs mainly on
the pore walls inside particles.
De Ridder D. J. (2012) [2], published a book on
adsorption of organic micro pollutants onto activated
carbon. In order to explain the capabilities of activated
carbon, an appreciation of its structure is most useful.
Much of the literature quotes a modified graphite-like
structure; the modification resulting from the presence
of micro crystallites, formed during the carbonization
process, which during activation, have their regular
bonding disrupted causing free valences which are very
reactive. In addition, the presence of impurities and
process conditions influence the formation of interior
vacancies, in the microcrystalline structures.
High magnification electron scanning
microscopy, at 20,000x magnification, has revealed the
presence of residual cellular structures. These were
previously unseen and unsuspected, except in the case
of wood-based activates which have sufficiently open
structures visible to the naked eye. Fig.1 shows the
microscopic structure of activated carbon.

Most theories attribute the structure of
activated carbon to be aromatic in origin, thus, allowing
the carbon structure itself to be described as aromatic in
