摘要
活性炭(AC)材料用于烟气脱硫与其表面化学结构有关,活性炭材料的表面改性是提高其烟气脱硫活性的有效途径。综述了活性炭材料的热处理、表面含氧含氮官能团、表面碱性基团、表面负载金属及其化合物以及含氮或含碘物质的掺入对其脱硫活性的影响。
The surface chemical groups of activated carbon（AC） materials influenced the removal of SO2 in flue gas, and surface modification of AC materials was an effective method for increasing desulfurization of flue gas. Several factors affecting desulfurization activity on AC materials including heat treatment, oxygen groups, nitrogen groups, basic groups, metals and their compounds loading and incorporation of nitrogen or iodine substances were summarized.
