The present study investigates the mineral carbonation process that produces sodium bicarbonate (NaHCO3) precipitates, which could be one carbon capture and utilization/storage option. The NaHCO3 precipitates are generated via the mineral carbonation of 3 g of NaOH-dissolved ethanol aqueous solution, of which the ethanol concentration ranges from 50.5 to 97% (for convenience, named 50.5S-97S). In this region, the amount of generated NaHCO3 precipitates is parabolically increased as the ethanol composition increased and is a maximum 5.82 g at 85S. However, the yield of NaHCO3 precipitates is at a maximum 5.7 mg/(g of NaOH.g of ethanol) [the mass of ethanol in the denominator is not the consumed value but the value used to calculate the yield of NaHCO3 precipitates] at 80S, which equates to the amount of CO2 that could be fixed by 3.0 mg of CO2/(g of NaOH.g of ethanol). At this condition, Na compositions in the precipitates and in the filtrate are 86.87 and 13.13%, respectively. In addition, ethanol concentrations of 50.5S-97S after carbonation are almost not changed as 50-97%, because ethanol is not a reactant of the carbonation in this region. Therefore, NaHCO3 precipitate, which is a CO2 fixation material that is widely used for various purposes, could be simply obtained via the carbonation of NaOH-dissolved ethanol aqueous solution with high yield, without ethanol loss. However, in the carbonation with solution less than 50.5%, NaHCO3 is not precipitated due to its relatively high water composition, and in a 97.5% or higher ethanol concentrated solution, sodium ethyl carbonate (SEC; C2H,COONa) begins to be precipitated. In addition, the amount of precipitated NaHCO3 increased linearly according to the amount of NaOH feed with a rate of 1.88 g of NaHCO3/g of NaOH at 80S, which corresponds to the amount of fixed CO2 being 0.99 g of CO2/g of NaOH.
