Description In situ nitrogen enriched carbon was synthesized from locally available low cost soybean as
the proteinaceous source. The material was synthesized by chemical activation using zinc
chloride followed by physical activation using CO2. The surface area of synthesized nitrogen
enriched carbon was found to be 811m2/g which is comparable with commercially
available activated carbon. The nitrogen enriched carbon was having a breakthrough
adsorption capacity of 23 mg/g at 120 �C which was almost three times higher in comparison
with the commercially available activated carbon for a gas mixture comprising 15%
CO2 balanced with helium. This high adsorption capacity was attributed to the presence
of nitrogen group within the carbon matrix, which was estimated to be about 0.64% as
determined using the Kjeldahl’s method. The presence of different nitrogen containing
groups assisting the adsorption of CO2 in the synthesized sample was also confirmed by
infrared analysis. For checking the consistent performance of the synthesized carbon,
multi-cycle adsorption–desorption studies were carried out at 30 and 75 �C in binary mixture
of CO2/N2.
