Analysis of wood combustion products

The data presented in this dataset are related to the research paper “Granulation of fly ash and biochar with organic lake sediments – A way to sustainable utilization of waste from bioenergy production” [1] in the context of waste material investigation and possible valorization instead of disposal. This article provides a comprehensive chemical and physical characterization of wood combustion products – fly ashes, bottom ashes, mixed ashes and biochar. Multiple analytical techniques and methodology were exploited to investigate the composition of wood combustion products, among them a loss on ignition, potentiometry, colourimetry, X-ray diffractometry, X-ray fluorescence spectrometry, inductively coupled plasma optical emission spectrometry, gas chromatography. General parameters detected were the content of dry matter, gravimetric water, volatile matter, amount of ash and fixed carbon. The elemental analysis involved determining C, H, N and O. Physical properties were described by bulk density, solid density, total porosity, electric conductivity, specific weight and mass ratio assessment of particle size distribution. The mineralogical composition was described by major crystalline phases of samples and the content of oxides. Chemical properties and composition were characterized by pH, the content of ammonium, nitrates, nitrites, exchangeable elements and cation exchange capacity as well as after the 3-step speciation and analytical quantification of trace and major elements (Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Se, Sr, Ti, Tl, V and Zn) and detection of polycyclic aromatic hydrocarbons.

本数据集所呈现的内容与研究成果论文《利用有机湖泊沉积物对飞灰和生物炭进行粒化——生物能源生产废物的可持续利用途径》[1]密切相关，该研究聚焦于废料材料的调查及其可能的增值化利用而非简单处置。该论文对木材燃烧产物——飞灰、炉底灰、混合灰和生物炭进行了全面的化学和物理特性描述。为探究木材燃烧产物的成分，采用了多种分析技术和方法，包括灼烧失重、电位滴定、比色法、X射线衍射、X射线荧光光谱法、电感耦合等离子体质谱法、气相色谱法等。检测的一般参数包括干物质含量、重力水含量、挥发性物质含量、灰分量和固定碳含量。元素分析涉及了碳、氢、氮和氧的测定。物理性质通过堆积密度、固体密度、总孔隙率、电导率、比重和质量比评估以及粒径分布进行描述。矿物组成通过样品的主要结晶相和氧化物含量进行描述。化学性质和组成通过pH值、铵、硝酸盐、亚硝酸盐、交换性元素和阳离子交换能力进行表征，以及经过三步物种化和分析定量后对微量和主要元素（包括Al、As、Ba、Ca、Cd、Co、Cr、Cu、Fe、K、Li、Mg、Mn、Mo、Na、Ni、P、Pb、Sb、Se、Sr、Ti、Tl、V和Zn）的检测，并对多环芳烃进行了检测。
