英文摘要: The carbon dioxide emission has to be efficiently controlled due to environmental, economic and social demands. Among the various technologies, gas absorption technology is of great importance for the capture of CO2 and to prevent global warming. In the present work, the absorption of carbon dioxide in alkanolamines in aqueous and vegetable oil medium was assessed and it was found that the absorption in organic medium is higher than in aqueous medium. Among the alkanolamines in various vegetable oil media, 2-amino-2-methyl-1-propanol (AMP) in the coconut oil medium was found to exhibit the highest absorption capacity for CO2 gas. The precipitate resulting after passing CO2 through AMP in the vegetable oil medium was analyzed by FT-IR, 1H NMR and 13C NMR spectroscopic techniques and identified as AMP-carbamate. The influence of various operating conditions such as amine concentration, reaction time, temperature and pressure of CO2 gas on the AMP-carbamate yield was analyzed. Under optimized conditions, the maximum yield of 52% of AMP-carbamate was obtained. Thus the AMP in vegetable oil medium emerges to be a promising candidate for capturing CO2 and for isolation of value added product (AMP-carbamate). © 2014 Elsevier Ltd. Citation statistics:
