摘要

活性炭可用作将 Co(III)TETA 还原成 Co(II)TETA 的催化剂,从而保持用 Co(II)TETA 溶液去除气流中 NO 的能力。硝酸钙被用来处理活性炭,以提高其在 Co(II)TETA 再生过程中的催化能力。以 1 克/50 毫升的固液比将活性炭在 65°C 的 0.3 摩尔/升硝酸钙溶液中浸泡 12 小时,然后在 400°C 的氮气中碳化 2 小时,可获得最大的 Co(III)TETA 转化率。傅立叶变换红外光谱、XPS、BET(Brunauer-Emmett-Teller)和 Boehm 滴定法的表征表明,硝酸钙改性增加了活性炭的比表面积和酸性基团。连续实验表明,改性后的活性炭去除 NO 的效率比原来的活性炭高 12%以上。

Research over the effect of activated carbon treated with calcium nitrate solution on the catalytic ability in the reduction of Co(III)Triethylenetetramine

Activated carbon can be used as a catalyst for the reduction of Co(III)TETA to Co(II)TETA so as to maintain the ability of removing NO from gas stream with Co(II)TETA solution. Calcium nitrate has been utilized to treat activated carbon to improve its catalytic ability in the regeneration of Co(II)TETA. The biggest Co(III)TETA conversion is gained by the carbon being soaked in 0.3 mol/L calcium nitrate solution at 65°C for 12 h with a solid/liquid ratio of 1 g/50 mL followed being carbonized at 400°C for 2 h in nitrogen. The characterization with Fourier transform infrared spectroscopy, XPS, BET (Brunauer-Emmett-Teller) and Boehm titration indicates that the modification with calcium nitrate increases the specific surface area and acidic groups on activated carbon. The continuous experiments reveal that the NO removal efficiency obtained by the modified carbon is over 12% up to that by the original one.
