Carbon capture and storage (CCS) is the option for reducing these harmful CO 2 emissions. While a variety of technologies and methods have been developed, the separation of CO 2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of capture materials with high separation performance and low capital cost are of paramount importance. Nanoporous carbon derived from leaf of cattail flower that found in all areas throughout Thailand, the biomass was previously pyrolyzed at 500 to 700C and the produced chars were further activated with NaOH, KOH, Na 2 CO 3 and K 2 CO 3 subsequently. Afterwards, the resulting materials were characterized by Scanning electron microscopy, Fourier-transform infrared spectroscopy and Raman scattering measurement. From this investigation, produced activated carbon will be efficient as an option for CO 2 emission control. © 2019 Elsevier Ltd. All rights reserved.

Global warming occurs when carbon dioxide and other air pollutions and greenhouse gases collect in the atmosphere and adsorb sunlight and solar radiation that have bounced of the earth's surface. It happens in the industrial section, Transportation section, forest fires and burnings. Has increase to the degree that they become significant contributors of much carbon dioxide in to the atmosphere [1], the principal methods used to capture CO 2 from post- combustion gases are absorption and membrane separation [2,3]. The methods based on CO 2 absorption by amines are commonly used and highly effective; however, there are some important technical and economic drawbacks [4]. * Corresponding author.
