摘要
建立了固定床烟气脱硫反应器,采用椰壳活性炭（AC）担载Cu制备脱硫剂CuO/AC,研究了煅烧温度、Cu担载量、脱硫反应温度及烟气成分对脱硫剂脱硫性能的影响.结果表明：CuO/AC脱硫剂煅烧温度为250℃时较适宜;Cu担载量为5%~7.5%、脱硫反应温度为200~250℃、烟气中有适量的O2时,CuO/AC脱硫剂具有较好的脱硫能力;再生温度为300℃时得到的再生脱硫剂的脱硫效果最好,但脱硫能力与新的脱硫剂相比有所下降.
CuO/AC desulphurizers were prepared using cocoanut shell activated carbon as the support and a fixed-bed flue gas desulfurization（FGD） reactor was set up,so as to study the influence of following factors on FGD performance of the desulphurizer,such as the calcination temperature,Cu loading capacity,desulphurizing temperature and gas component,etc.Results show that for higher FGD performance of CuO/AC desulphurizer,the calcination temperature would better be kept at about 250 ℃,Cu loading capacity in 5%-7.5%,desulphurizing temperature in 200-250 ℃ and O2 concentration in flue gas at a moderate degree.Regenerated desulphurizer would have better performance if the regeneration temperature is kept at 300 ℃,however,its desulphurization reactivity is worse than the original CuO/AC desulphurizer.
