Abstract
In this paper, the handling situation of industrial by-product gypsum at home and abroad was laborated, and the influence of carbon on gypsum pyrolysis reaction was studied. The experimental results show that the presence of carbon could greatly reduce the decomposition temperature of gypsum. The temperature of the reaction tower in flash furnace could satisfy the temperature requirement of gypsum decomposition when carbon was present. It provided the basis for the treatment and utilization of two kinds of industrial solid waste gypsum, activated coke and industrial gypsum in this study, and it implemented turning waste into treasure.关键词
