Study of the Slow Pyrolysis of Lignin, Hemicellulose, and Cellulose and the Effect of Their Interaction in Plant Biomass
The pyrolysis of two types of raw materials of plant origin (sawdust and sunflower husks), components of the organic matter of biomass (hemicellulose, cellulose, and lignin), and model mixtures prepared from components in accordance with their fractions in the raw materials was studied. Pyrolysis of the materials was carried out using TGA and a laboratory setup with a fixed bed reactor. The distribution and composition of the products were determined at pyrolysis temperatures of 350, 425, 500, and 575°C. Experimental data obtained with the biomass samples and model mixtures were compared with calculated values obtained based on the pyrolysis of individual components and their fractions in the biomass. The possibility of predicting the distribution of pyrolysis products depending on the component composition was investigated. The influence of intercomponent interaction in biomass on the yield and composition of pyrolysis products was revealed.
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.
