METHOD FOR GENERATING A HYDROGEL FROM A CO2 GAS STREAM

The present disclosure relates to a method of sequestering carbon dioxide which comprises the steps of capturing carbon dioxide from an industrial gaseous waste stream and/or the atmosphere, converting a CO2 from the CO2 gas stream into a (COOH)2 and combining the (COOH)2, a mono-alcohol (X-OH), pre...

Zusammenfassung:	The present disclosure relates to a method of sequestering carbon dioxide which comprises the steps of capturing carbon dioxide from an industrial gaseous waste stream and/or the atmosphere, converting a CO2 from the CO2 gas stream into a (COOH)2 and combining the (COOH)2, a mono-alcohol (X-OH), preferably CH3CH2OH, and a first acid catalyst comprising a H2SO4 at a temperature ranging from about 80° C. to about 100° C. and under atmospheric pressure to produce an ester comprising a (COOX)2 and preferably (COOEt)2; and the ester obtained is reacted with a polyol, preferably glycerine to form a polyester, preferably the polyester is a hydrogel. The present disclosure further relates to the use of a hydrogel which is obtainable by said method.
