CO(2) Separation and Capture Properties of Porous Carbonaceous Materials from Leather Residues

Carbonaceous porous materials derived from leather skin residues have been found to have excellent CO(2) adsorption properties, with interestingly high gas selectivities for CO(2) (α > 200 at a gas composition of 15% CO(2)/85% N(2), 273K, 1 bar) and capacities (>2 mmol·g(−1) at 273 K). Both CO...

Sumario:Carbonaceous porous materials derived from leather skin residues have been found to have excellent CO(2) adsorption properties, with interestingly high gas selectivities for CO(2) (α > 200 at a gas composition of 15% CO(2)/85% N(2), 273K, 1 bar) and capacities (>2 mmol·g(−1) at 273 K). Both CO(2) isotherms and the high heat of adsorption pointed to the presence of strong binding sites for CO(2) which may be correlated with both: N content in the leather residues and ultrasmall pore sizes.
