研究了一种新型软锰矿改性活性焦(ACP)的混炼再生性能。ACP(ACP-Rn)的循环再生表明，ACP是一种良好的脱硫剂。经过5次再生循环(ACP-R5)后，样品的硫容为178 mg/g，比ACP的161 mg/g提高了10.8%。SBET和孔体积随再生循环次数的增加而增加，但不是SO2脱除的限制因素。较好的表面官能团，尤其是碱性中心，对提高ACP-Rn的脱硫性能有较大贡献。负载金属在脱除SO2中起着重要的作用。从第一次再生循环到第五次再生循环，ACP中金属硫酸盐的积累量迅速增加，然后在进一步再利用期间保持相对稳定。ACP再生过程分为三个阶段：干燥、反应和热解。包裹金属对热解有较强的促进作用。
The regeneration properties of a novel pyrolusite-modified activated coke (ACP) by blending method were investigated. Cyclic regeneration of ACP (ACP-Rn) shows the ACP was a good desulfurizer. The sample had the best desulfurization performance after five regeneration cycles (ACP-R5), and its sulfur capacity was 178 mg/g, 10.8% higher than that of ACP (161 mg/g). The SBET and pore volume were increased with the number of regeneration cycles, but they were not the limiting factors of the SO2 removal. The better surface functional groups, especially the basic sites, contributed more to the improvement of desulfurization performance of ACP-Rn. The loaded metals played an important role in SO2 removal. The accumulation of metal sulfate in ACP rapidly increased from the first to fifth regeneration cycles and then remained relatively stable during further reuse. The ACP regeneration process divided into three stages: drying, reaction, and pyrolysis. The wrapped metals relatively enhance the pyrolysis and acted ...
