Abstract

A new approach using reed pulping black liquor by hydrothermal reaction followed by fast carbonization at 350 °C in fluidized bed reactor for 5 minutes was proposed in this paper. The BET specific surface area generated at optimum conditions reached 390 m² g_-1. The CO₂ selectivity over CH₄ and N₂ comparable to commercial activated carbons was obtained. The isosteric enthalpies of adsorption for CO₂, CH₄ and N₂ on the resultant carbon sample prepared at optimum conditions show surface heterogeneity. The kinetic results indicate its potential for separation of carbon dioxide from carbon dioxide/methane mixture.
