PRADA, Abelardo  and  CORTES, Caroll E. Thermal decomposition of rice husk: an alternative integral use. Orinoquia [online]. 2010, vol.14, suppl.1, pp.155-170. ISSN 0121-3709.

The present work was aimed at capturing the gases of combustion of rice husk to transform them into calcium carbonate (CaCO₃), a substance useful in agriculture. It was shown that the combustion gases from the rice husk can be captured in aqueous solutions of KOH and NaOH, of which CaCO₃ is obtained by adding CaCl₂ aqueous. Characteristics were determined from the combustion process (mass scale, temperature and mass of ash) of the capture of gases (reaction time, pH and t ° C), the precipitation of CaCO₃ (mass of CaCl₂ required) and the mass CaCO₃ obtained.

Keywords : Combustion; integral use; capture of carbon dioxide; calcium carbonate; land use.
