A Fast Approach For Preparation Of Adsorbent From Reed Black Liquor And Its Performance In Equilibrium And Kinetic Gas Separation, G. Yang, Yong Sun, C. Wen, J. Zhang
Research outputs 2014 to 2021
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.
