Gas Adsorption on Activated Carbon

Abstract

Since the beginning of industrial revolution, greenhouse gas emissions have increased more than 30 % in the atmosphere, and resulted in various environmental impacts. Carbon dioxide emissions are expected to increase by more than 50% over the next 20 years. Methane levels have more than doubled over the last 150 years. As a result, its capture has become necessary for ecological balance. Many researches based on new technology has been sorted so far for gas capture, storage, and utilization. Many solvents like monoethanolamine (MEA), chilled methanol and dimethyl ether of polyethylene glycol have been conventionally used for CO2 capture using absorption technology. The removal of gases with solid regenerable adsorbents have proved to be advantageous as they are regenerable with less energy consumption. This study is focused on the adsorption of gases, mainly CO2 and CH4 on activated carbon by volumetric method.
