Abstract

In the efforts to combat the increase in the excess emissions of anthropogenic CO2, CCS technologies such as solid sorbents for CO2 capture have been explored. Activated carbon is considered one of the most promising adsorbents due to its many advantages, such as its good thermal stability and excellent adsorption capacity. Activated carbon prepared from date seeds agricultural biomass have already been developed and are used in many industrial applications. However, there is not much research that explored their potential for CO2 capture applications. This study reports the preparation of chemically activated Activated carbon (AC) using KOH. Different impregnation ratios and activation temperatures were studied to find the best preparation combination for high CO2 capture capacity. At the optimized impregnation ratio of 2.5:1 and activation temperature of 600 °C, the produced AC had the highest adsorption capacity of 2.18 mmol/g and BET surface area of 1033.09 m2/g.
