LA DESCOMPOSICIóN TéRMICA DE LA CASCARILLA DE ARROZ: UNA ALTERNATIVA DE APROVECHAMIENTO INTEGRAL

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.
