技術說明

本發明是一種複合加硫改質粉狀活性碳之製備方法：特別是關於創新型複合加硫改質技術，首先粉狀活性碳乾燥處理，乾燥後之粉狀活性碳進行液相硫化鈉溶液浸漬處理，最後進行氣相元素硫加熱處理的複合加硫改質之粉狀活性碳製備方法。發明較佳實施之複合加硫粉狀活性碳之製備方法包含：粉狀活性碳乾燥處理步驟：第一次液相加硫-硫化鈉溶液浸漬步驟，得到Na2S PAC；第二次氣相加硫-元素硫加熱處理步驟，得到Na2S+S0PAC。本實驗較佳實施例之複合加硫改質活性碳之複合加硫順序係先液相改質，而後氣相改質。因先液相改質再氣相改質後之活性碳，硫含量為11.58%，在高溫150℃吸附條件下，氯化汞吸附量為43,935 μg-HgCl2/g-C，而元素汞吸附量為33,789 μg-Hg0/g-C。 This invention involved a preparation methods that the composite powdered sulfurized activated carbons (PACs)were produced by combining two sulfur impregnation: particularly an innovative composite sulfurization technology to obtain composite sulfurized PACs, the PACs need impregnation in Na2S(aq) and then heated with S0(g). Firstly, the raw PACs were dried; secondly, the Na2S PACs were obtained after impregnated in aqueous-phase Na2S(s); finally, Na2S PACs were heated in the gas-phase S0(g). The experimental sulfurization sequences, in which the removal efficiency of Hg0 and HgCl2 was better, were Na2S(aq) impregnation with priority and heat in S0 followed. The sulfur content of Na2S+S0 PACs reached up to 11.58%. The adsorptive capacity of HgCl2 and Hg0 was 43,935 μg/m3 and 33,789 μg/m3 respectively at 150℃.
