Abstract

In this paper, we have studied the patterns of the HCl absorption by calcium-containing sorbents under countercurrent gasification in the filtration combustion mode. Experiments have been performed in a vertical batch reactor at temperatures of up to 1200°C. The following sorbents have been employed: calcium oxide and calcium carbonate (in the form of chalk and marble). The efficiency of HCl absorption by sorbents has been estimated. The completeness of HCl uptake has been shown to be limited by partial hydrolysis of the calcium chloride formed in the high-temperature zone.
