Ultimate and proximate analyses, HHV and BET surface area have been assessed in the unburned materials obtained by combustion in a conical spouted bed of four types of vegetable biomasses representative of forestry residues, grass and food industry. The results show that the materials are mainly of carbonaceous structure, which stems from the incomplete decomposition of cellulose and lignin, and their content decreases with combustion temperature. The unburned materials have a high surface area, which is of the same order as certain commercial active carbons, rendering them suitable properties for use as low-cost adsorbent. In order to verify this fact, removal efficiencies have been determined in amoxicillin removal tests, and the characteristic parameters, as well as mass transfer coefficients, have been calculated for two adsorption models following Langmuir and Freundlich isotherms. The results confirm that this byproduct obtained in the recovery of energy from waste biomass performs well in the removal of emerging pollutants from wastewater, and is a viable alternative of commercial adsorbents.

最终和最接近的分析，HHV和BET表面积已通过在代表植物残渣，草料和食品工业的四种蔬菜生物质的锥形喷头床中燃烧获得的未燃烧物料中进行了评估。结果表明，该材料主要为碳质结构，是由于纤维素和木质素的不完全分解所致，其含量随燃烧温度的降低而降低。未燃烧的材料具有高的表面积，该表面积与某些商业活性炭的表面积相同，从而使其具有用作低成本吸附剂的合适性能。为了验证这一事实，已在阿莫西林去除测试中确定了去除效率，并确定了特性参数以及传质系数，分别根据Langmuir和Freundlich等温线计算了两个吸附模型。结果证实，从废物生物质中回收能量获得的这种副产物在从废水中去除新兴污染物方面表现良好，并且是商业吸附剂的可行替代品。
