Content Summary | Organic petrology and detailed physicochemical properties has been undertaken on twenty six Greek low
rank coals (peat, peaty lignites, lignites of both matrix and xylite-rich lithotypes, and sub-bituminous
coals in order to evaluate the increase of their adsorptive surface area by pyrolysis.
The results show that surface area of activated coal samples increased substantially and in some
more than the commercial one. The increase in surface area was higher the higher the carbon content
and the lower the ash content.
The adsorption capacity of phenols and the decrease of COD (Chemical Oxygen Demand) in olive
oil mil wastewater disposals were measured in selected samples as well as the decrease of COD and
the adsorption of nitrogen and phosphorus from a solution which simulates city waste disposals were
measured in 14 selected Greek lignites and 1 commercially available activated lignite sample (HOK).
The maximum recorded adsorption of phenol was 30.6 mg/g of activated lignite while the commercial
one (HOK) adsorbed 16 mg/g of activated lignite. The COD reduction was 1262 mg of COD/g
of activated lignite while in the commercial one the reduction was 439 mg of COD/g of activated lignite.
The maximum adsorption of N and P from the simulated city waste liquid was 6.41 mg/g of activated
lignite and 2.52 mg/g of activated lignite, respectively. while the commercial one (HOK)
adsorbed 2.84 mg/g and 2.42 mg/g, respectively. Finally, the COD reduction was 50.28 mg/g of activated
lignite and 34.92 mg/g for the commercially one (HOK).
The results show that Greek activated lignites can be used successfully for cleaning industrial and
city wastes. These findings open the door for the economic exploitation of small to medium size lignite
deposits in Greece, which are widespread in Greece. | en |
