Abstract

The main objective of the project is to stndy the adsorption behaviour of carbon dioxide on different adsorbent varying in surface area, porosity and micropore characteristic. Beside, the study of modifying alumina with metal oxide is also conducted to observe any enhancement in adsorption. The last objective is to stndy the characteristic of the adsorbent used in terms of surface area, micropore volume and porosity. The adsorption process is conducted experimentally using an simple adsorption column while the sample characterization is done using AutoSorb and Quanta-Chrome software. For adsorption, 4 types of adsorbent is used; 2.5mm activated carbon, 1.5mm activated carbon, activated alumina and modified alumina (added calcium oxide). Four pressures were used for adsorption ranging from 25kPa to 55kPa. After the data had been obtained, it is tabulated and graph using Microsoft Excel. From the results, it is found that porosity, surface area and micropore volume have a big influence on the adsorption capacity of the adsorbent. The highest intake of carbon dioxide is by 1.5mm activated carbon and the least is activated alumina. From the BET and DR results, 1.5mm activated carbon has the largest surface area while alumina has the least. Granular size also plays and important part in adsorption. This project provides a basic for a better understanding in the adsorption process as this process in very important in the current industries.
