Surface modification of activated carbons for CO2 capturePevida García, CovadongaGonzález Plaza, MartaArias Rozada, BorjaFermoso Domínguez, JavierRubiera González, FernandoPis Martínez, José JuanActivated carbonSurface modificationThermal analysisCO2 captureAdsorption8 pages, 6 figures, 4 tables.-- Printed version published on Sep 15, 2008.The reduction of anthropogenic CO2 emissions to address the consequences of climate change is a matter of concern for all developed countries. In the short term, one of the most viable options for reducing carbon emissions is to capture and store CO2 at large stationary sources. Adsorption with solid sorbents is one of the most promising options. In this work, two series of materials were prepared from two commercial activated carbons, C and R, by heat treatment with gaseous ammonia at temperatures in the 200–800°C range. The aim was to improve the selectivity and capacity of the sorbents to capture CO2, by introducing basic nitrogen-functionalities into the carbons. The sorbents were characterised in terms of texture and chemical composition. Their surface chemistry was studied through temperature-programmed desorption tests and X-ray photoelectron spectroscopy. The capture performance of the carbons was evaluated by using a thermogravimetric analyser to record mass uptakes by the samples when exposed to a CO2 atmosphere.This work was carried out with financial support from the Spanish MEC (Project CTM2005-03075/TECNO).
