چکیده
|
Activated carbon was produced from okpara sub-bituminous coal and ogwashi brown lignite coal of nigeria through steam activation at 900 °c and 960 °c each for 30 min and 60 min. okpara and ogwashi precursor coals had carbon content of 67.41 and 64.47%,respectively,whereas the bulk density and the ash content were 0.59-0.68 g/ml and 2.56-9.91%,respectively. the former exhibited up to 901.0 mg/g iodine number and brunauer emmett teller (bet) surface area of 604 m2/g while the latter,iodine number of 998.0 mg/g and 669 m 2/g bet surface area. both showed adequate porosity indicative of their potential for utilization for commercial production of active carbons.
