A STUDY OF CARBON DIOXIDE (CO2) ADSORPTION USING COCONUT SHELL CHARCOAL AS ADSORBENTS

Abstract

The emission of greenhouse gases, such as CO2, methane (CH4) and nitrous oxide (N2O) has been increased dramatically so lately and exceeded far the pre - industrial values. Main factors that contribute to the increasing of those gases are burning of fossil fuels on industry, the usage on transportation, some resident uses and usage in agriculture. As the emission of these gases are becoming severe, it is now necessary to develop technology that will allow us to utilize fossil fuel while reducing the emission of greenhouse gases. Among all these gases, CO2 is considered as the major contributor to the global warming. Therefore, it is necessary to develop a very cost effective technology that can reduce the CO2 level. Apart of that, various technology have been develop to capture CO2 which are absorption, adsorption, membrane and cryogenic processes. Among all these technologies, adsorption is considered as promising method for capturing CO2. However, its all depends on the characteristics of the adsorbent itself that must possesses high surface area, high porosity and micro porosity and easy to design pore structure. Regardless of that, this study have focused on the CO2 adsorption by using coconut shell charcoal as adsorbent. The adsorbent was produced at three different carbonization temperature which are 400, 500 and 600 . Result obtained shows that the best carbonization temperature for CO2 adsorption process is 500 and the best adsorbent mass loading was at 20 gram. From these result, it can be concluded that the carbonization temperature and adsorbent mass loading did effects the CO2 adsorption process
