Description

<p>In this study we prepared porous carbon samples from various carbonaceous materials, such as biomass and coal, and evaluated their CO2 adsorption performance. First, activated carbons were prepared by heat treatment of a mixture of melamine as a nitrogen source and K2CO3 as a chemical activator added to the carbonaceous resource, and their pore properties were investigated in detail. Then, the CO2 adsorption performance of the prepared activated carbons was tested. It was found that activated carbon with well-developed pores could be prepared by using carbonaceous resources with low carbon and low ash contents. The specific surface area (SAA), micropore volume and CO2 adsorption of the prepared activated carbon showed relatively good correlation. In other words, we found that the SAA and micropore volume affected the CO2 adsorption performance. Additionally, the optimum micropore diameter for CO2 adsorption was identified as 0.7–1.0nm.</p>
