Fremgangsmåde til fremstilling af calciumoxid

摘要

Process and apparatus implementing a process for forming calcium oxide from pulverulent calcium carbonate, according to which an initial bath of pulverulent calcium oxide is produced in a reactor as a fluidised bed which is heated electrically to a temperature higher than of the order of 900 DEG C, and the said pulverulent calcium carbonate is then introduced continuously into the bath while always keeping the temperature of the bath higher than of the order of 860 DEG C by electrical heating in order to dissociate the said calcium carbonate into calcium oxide and carbon dioxide. ……
