Coal Briquette Scientific.Net

Abstract: Clean coal briquette is one of the most effective techniques to remove SO 2 from coal combustion by using sulfur-retention agent to retain sulfur in coal residuals. Ca(OH) 2 has been proved to be an effective sulfur-retention agent. CaSO 4 as the primary sulfur-containing product, however, is thermal unstable at high temperatures. It has been reported that SiO 2, Al 2 O 3, Fe 2 O 3 ...
