This study aims to demonstrate a novel method for removing toxic chemicals using soot produced from wood and herbaceous biomass pyrolyzed in a drop tube reactor and tire pyrolytic carbon black. The influence of ash content, nanostructure, particle size, and porosity on the filter efficiency of steam activated carbon materials was studied. It has been shown for the first time that steam activated soot and carbon black can remove phenol and chloride with filter efficiencies as high as 95%. The correlation of filter efficiency to material properties showed that the presence of alkali and steam activation time were the key parameters affecting filter efficiencies. This study shows that steam activated biomass soot and tire carbon black are promising alternatives for the cleaning of wastewater.
本研究旨在展示一种使用在滴流管反应器中热解木质和草本生物质以及轮胎热解炭黑产生的烟尘去除有毒化学物质的新方法。研究了灰分含量、纳米结构、粒径和孔隙率对蒸汽活化炭材料过滤效率的影响。首次表明，蒸汽活化烟尘和炭黑可以去除苯酚和氯化物，过滤效率高达 95%。过滤效率与材料特性的相关性表明，碱的存在和蒸汽活化时间是影响过滤效率的关键参数。本研究表明，蒸汽活化生物质烟尘和轮胎炭黑是废水净化的有前途的替代品。
