Fly ash zeolites
WebAbstract Circulating fluidized bed combustion (CFBC) is known for its ability to significantly reduce the emission of NO x and SO 2 from coal combustion. However, the fly ash produced from CFBC (CFBFA) is impractical for use as a construction material due to its low pozzolanic activity. WebMay 28, 2016 · This study was focused on synthesis of zeolite X from coal fly ash using the alkaline fusion method coupled with a novel method which uses ultrasonic energy for aging step.
