The synthesis gas or hydrogen‐rich gas, at longer residence times and higher temperatures, is frequently the target of pyrolysis biomass. Biochars obtained at such conditions contain less functional groups but they are more effective for longer‐term soil C storage. The aim of this study was to elucidate the adsorption mechanisms and the effect of the ageing process on high‐temperature biochar towards lead adsorption. The biochars under study were produced from the pyrolysis of almond wood and olive tree pruning.

高温生物炭吸附铅及老化过程的机理

在更长的停留时间和更高的温度下，合成气或富氢气通常是热解生物质的目标。在这样的条件下获得的生物炭含有较少的官能团，但它们对于长期的土壤碳储存更有效。这项研究的目的是阐明吸附机理以及老化过程对高温生物炭对铅吸附的影响。所研究的生物炭是由杏仁木和橄榄树的热分解产生的。
