This work consists of the preparation of briquette from carbonized rice's husks in low pressure. The results demonstrate are necessary a fine granulation of the rice's husks coal to obtainment of briquettes. The ultimate analysis of the briquette didn't detect the presence of nitrogen and sulfur, and that prevents the formation and emission of acid gases that can produce corrosion in the equipment and pollute the atmosphere. The performance of the briquette production was superior to 80%. The briquettes present high heating value (HHV) 17,73MJ/kg and adequate mechanic resistance for the use in gasifier-engine system.
