Abstract:
Through the study on influence factors of the carbonic acid reaction of phosphogypsum decomposition slag in the three-phase fluidized bed, the effect of different factors on the transformation of CaS in the phosphogypsum decomposition slag was discussed. Experiments show that Increasing CO2 gas flow and extending reaction time have benefit for the transformation of CaS. The conversion rate of CaS was increased firstly and then tended to flatten with the increase of the liquid-solid ratio. The rise of reaction temperature has a weak inhibitory effect for the transformation of CaS. Comparing with tank reactor, three-phase fluidized bed reactor is more advantageous to the carbonic acid reaction of phosphogypsum decomposition slag.
