Abstract:This paper presents our study on removal of carbon dioxide (CO2) greenhouse gas emissions by using the mixture of ammonia and soil. CO2 capture capacity using this method is 15% higher than the sum of ammonia chemical absorption capacity and soil physical adsorption capacity. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) are utilized to study this synergism. The removal effect is not only reflected in ammonia chemical reaction with CO2. CO2 can also be absorbed by ammonium bicarbonate (NH4HCO3) crystal, which is the main component of the product, or wrapped in the pore of the crystal or packed in the gap between the crystal and the soil. CO2 can be permanently deposited as carbonated minerals in the subsoil earth layers.
