Carbon dioxide (CO2) is one of the anthropogenic greenhouse gases. The escalated CO2 concentration in the atmosphere is the primary driver to global warming issue. To mitigate this problem, carbon adsorbent has been considered as a promising porous solid adsorbent to capture CO2 from power plants; however it still gives low adsorption capacity. To improve their CO2 adsorption capacity, an introduction of nitrogen content on carbon adsorbent has been focused. Accordingly, in this research, petroleum residue (PR), which is the remaining material after the distillation of crude oil, was selected as a carbon source because it gives high carbon yield and low cost. Melamine (MM) was used as a nitrogen source to incorporate with petroleum residue. The effect of nitrogen doping ratio on petroleum residue (MM:PR) was investigated with MM:PR ratio of 0:1, 1:7, 1:3, and 1:1. Then, the nitrogen-doped petroleum residue was produced via a thermal process followed by a physical activation using CO2 at 900 °C. Finally, CO2 adsorption capacities were studied by using an equilibrium volumetric adsorption apparatus. The preliminary results showed that increasing the nitrogen doping ratio can improve the CO2 adsorption capacity due to the occurring of both physisorption and chemisorption.
