Facile Preparation of Porous Carbon Derived from Industrial Biomass Waste as an Efficient CO₂ Adsorbent.

ABSTRACT: A porous carbon CO₂ adsorbent based on soybean cake (industrial biomass waste) has been successfully prepared by direct carbonation, following KOH activation. The prepared porous carbon adsorbent exhibits efficient CO₂ capture performance with the highest adsorption capacity of 4.19 and 6.61 mmol/g at 298 and 273 K under atmospheric pressure, respectively. Moreover, the porous carbon adsorbent also shows good static CO₂ adsorption capacity at a low pressure (0.15 bar) with an uptake of 1.26 mmol/g and an equally ideal dynamic CO₂ capture capability with an uptake of 1.28 mmol/g (15% CO₂) at 298 K. Additionally, the ideal adsorbed solution theory (IAST) model has been used to measure the selectivity of the porous carbon, and the IAST fa
