Abstract: The impregnating and drying technics in vacuum condition of nuclear-grade activated carbon were established based on our experimental results. In this paper, a large-scale process and its integrated equipment to produce impregnated activated carbon were designed via heat balance calculation. This equipment can produce impregnated activated carbon in a continuous impregnation and pre-drying mode with stable quality, high efficiency, short time, and no dust pollution in the process.

Key words: activated carbon, impregnation, pre-drying
