摘要

本文介绍了对咖啡生产过程中产生的农业废弃物(咖啡壳和羊皮纸)和农用工业废弃物(两种废咖啡渣)进行热解的研究结果。使用热重分析仪(TG)和傅立叶变换红外光谱仪(FTIR)对热解过程中样品重量损失的温度依赖性进行了研究,并对主要挥发性物质进行了定性分析。在 5、10、20 和 30 K/min 四种加热速率下,样品的主要热分解阶段得以呈现。图中显示了四种材料热解产物挥发性成分的红外光谱分析结果,并绘制了主要气态热解化合物吸收带强度的温度相关性曲线。

A Combined TG–FTIR Study on the Pyrolysis of Waste Generated in the Coffee Production Chain

A Combined TG–FTIR Study on the Pyrolysis of Waste Generated in the Coffee Production Chain

The results of a study on the pyrolysis of agricultural (coffee husks and parchment) and agroindustrial (two types of spent coffee grounds) waste from coffee production are presented. A study of the temperature dependence of the weight loss of samples during pyrolysis and the qualitative analysis of the main volatile substances were carried out using a thermogravimetric analyzer (TG) coupled with a Fourier transform infrared spectrometer (FTIR). The main stages of thermal decomposition of the samples were presented at four heating rates of 5, 10, 20, and 30 K/min. The results of an analysis of IR spectra for the volatile components of pyrolysis products of four materials were shown, and the temperature dependences of the absorption band intensities of the main gaseous pyrolysis compounds were plotted.

期刊介绍: The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
