CO2 Capture by Alkaline Carbonation as an Alternative to a Circular Economy

In order to combat global warming and climate change in a sustainable way, it is necessary to capture the anthropogenic CO2 emitted by different industrial sources and use it as a raw material to obtain a matrix of products for industrial use, such as metal carbonates. Therefore, this work presents...

Summary:In order to combat global warming and climate change in a sustainable way, it is necessary to capture the anthropogenic CO2 emitted by different industrial sources and use it as a raw material to obtain a matrix of products for industrial use, such as metal carbonates. Therefore, this work presents the results of CO2 capture and conversion into carbonates using Sr and Ba alkaline solutions in a semi-continuous batch reactor. The results indicate that the effects of morphological characterization, purity of solids, and reaction time at ambient temperature and atmospheric pressure conditions is an inexpensive alternative process that is easily implemented in small industrial enterprises. The results yielded a 40% conversion of CO2 at the best reaction conditions with an aqueous solution of Sr(OH)2.
