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.
