Combustion of chloridated plastic such as PVC in solid wastes plays an important role in the HCl pollutant in air environment. The removal of HCl is classified as two sorts, i. e., the flue gas dechlorination and the reduction during combustion, of which the latter receives intensive concern due to its high economy and facility. In this paper, both HCl emissions and its removals by alkali-based sorbents during PVC combustion were conducted in an externally heated, quartz-tube fixed bed reactor. The conversion of HCl increased leniently from 83% to 88%, as temperature increased from 700 to 900℃. The calcium-based sorbents including CaCO_3,Ca(OH)_2,Ca(CH_3COO)_2 exhibited high HCl removal efficiencies from 68% to 79%, while magnesium-based sorbent less than that of 3%. Influences of operational variables, such as size of sorbents, Ca/Cl molar ratio and combustion fume compositions, on the HCl reduction were discussed.
