Назив: | Pyrolysis Kinetic Modelling of Wheat Straw from the Pannonian Region | Аутори: | Pešenjanski I. Miljković, Biljana Vićević M. |
Датум издавања: | 1-јан-2016 | Часопис: | Journal of Combustion | Сажетак: | © 2016 Ivan Pešenjanski et al. The pyrolysis/devolatilization is a basic step of thermochemical processes and requires fundamental characterization. In this paper, the kinetic model of pyrolysis is specified as a one-step global reaction. This type of reaction is used to describe the thermal degradation of wheat straw samples by measuring rates of mass loss of solid matter at a linear increase in temperature. The mentioned experiments were carried out using a derivatograph in an open-air environment. The influence of different factors was investigated, such as particle size, humidity levels, and the heating rate in the kinetics of devolatilization. As the measured values of mass loss and temperature functions transform in Arrhenius coordinates, the results are shown in the form of saddle curves. Such characteristics cannot be approximated with one equation in the form of Arrhenius law. For use in numerical applications, transformed functions can be approximated by linear regression for three separate intervals. Analysis of measurement resulting in granulation and moisture content variations shows that these factors have no significant influence. Tests of heating rate variations confirm the significance of this impact, especially in warmer regions. The influence of this factor should be more precisely investigated as a general variable, which should be the topic of further experiments. | URI: | https://open.uns.ac.rs/handle/123456789/5004 | ISSN: | 20901968 | DOI: | 10.1155/2016/9534063 |
