DETAILS

DEFINITION

Activated carbon is a carbonaceous material characterized by a well developed pore structure and a very large internal surface area.

These characteristics provide activated carbon with a very strong adsorptive property.

PORE STRUCTURE OF ACTIVATED CARBON

a – micropores

b , f – mesopores (spherical and cilindrical)

c , e , d, – macropores (passing, internal, superfi cial)

RAW MATERIAL

Activated carbon is mainly produced from

– coal

– coconut shell

– wood

The yield of activated carbon is in the range between 15-35 % depending upon the raw material.

Generally coal gives high yield (30-35%) while coconut shell gives a lower yield (15-20%).

The approximate carbon content for different raw materials is shown in table 1.

Coal

65%-70%

Coconut   shell

Wood

 CLASSIFICATION OFACTIVATED CARBON

GRANULAR

Mainly used for water treatment (potable, urban and industrial waste water)

Different mesh size

Different starting material (coconut, mineral, vegetal)

EXTRUDED ( PELLET )

Mainly used for air treatment

Different diameter 2 – 3 – 4 mm (most common)

Generally mineral based

POWDER

Used for water treatment (drinking and waste)

Industrial process (wine industry, pharmaceutical, food industry)

Air treatment (incinerators)

Size: generally under 325 mesh

Different raw material (coal, coconut, vegetal)

CHARACTERIZATION OF ADSORPTION CAPACITY

The adsorption capacity of activated carbon is determined mostly by two factors.

INTERNAL SURFACE AREA

It is determined by mean of N2 adsorption and represent the surface area of the activated carbon and it is expressed in m2/g.

Internal surface area varies in the range 500-1800.

PORE SIZE DISTRIBUTION

Micropore: 0-20 A°

Mesopore: 20-50A°

Macropore: > 50 A°

Micropores and mesopores are supposed the be the most effective for the adsorption phenomenon and represent 80-90 % of the pore distribution.

Distribution of pores depends upon the starting material.

Coconut shell a.c. have a predominance of micropore (roughly 90%).

Coal based a.c. have a wide pore distribution (micropore/mesopore distribution is 60/30%).

Wood – peat based a.c. have high proportion of macropore (40-50%).
