Kinetic Parameters of Thermal Decomposition of Biofuels and Its Oil-Containing Composites

The kinetic features of the decomposition of fuel pellets formed from birch phloem and its composites with the addition of oil-containing waste (OCW) were studied by methods of thermogravimetric analysis carried out in various atmospheric conditions. The characteristic temperature ranges of thermal decomposition of the materials from which pellets are formed were identified. The rates of mass loss and activation energy at the main stages of thermal decomposition were evaluated. And the combustion indices of composite compositions were determined to identify the possibility of using such compositions as alternative fuels. By evaluating activation energies for each stage of sample decomposition, the limiting influence of certain stages of the thermal destruction process was established.
