amp;ggr;-Al2O3 sorbent impregnated with alkali salt and CuO

摘要

The present invention relates to a &ggr;-Al₂O₃ sorbent impregnated with alkali salt and CuO, which has a superior SO₂ sorption capacity and a high regeneration conversion rate. A &ggr;-Al₂O₃ sorbent of the present invention is impregnated with alkali salt and copper oxide, whose alkali salt and copper oxide(CuO) contents are 1 to 10 wt. % and 5 to 20 wt. % against 100 wt. % &ggr;-Al₂O₃ carrier, respectively. The &ggr;-Al₂O₃ sorbent of the invention has a superior SO₂ sorption capacity and a high regeneration conversion rate, which facilitates efficient removal of SO₂ by the conventional dry method.
