Algorithm for the interpretation of mass spectra in the study of thermochemical conversion of lignocellulosic raw materials using complex combined thermal analysis

Kozlova M., Penzik M., Shamansky V. Algorithm for the interpretation of mass spectra in the study of thermochemical conversion of lignocellulosic raw materials using complex combined thermal analysis // E3S Web of Conferences. Т.114. ID: 06010. 2019. DOI: 10.1051/e3sconf/201911406010 This article proposes a method for processing data obtained using the TA-MS complex. To search for calibration coefficients, the method includes solving a quadratic programming problem. To test the method of searching...

Thermoanalytical study of drying kinetics of lignocellulosic fuels

Donskoy I.G., Kozlov A.N., Shamanskiy V.A. Thermoanalytical study of drying kinetics of lignocellulosic fuels // Journal of Physics: Conference Series. Vol.1261. No.1. ID: 012009. 2019. DOI: 10.1088/1742-6596/1261/1/012009 Lignocellulosic matter is usually hydrophilic, so its drying, in addition to the heat of the phase transition for water, also requires compensation of adsorption energy. In the present work experimental studies have been carried out to quantify the moisture adsorption energy,...
