ABSTRACT

The aim of this article is to assess the impact of changes in particle size on the production yield during thermal degradation – pyrolysis process. For the purpose of this research the energy grass – black bent grass (Agrostis gigantea) was selected. The input material has been tested in four different granulometric fractions – original unadjusted material, crushed material, and also in the form of two kinds of pellets of different size.

For pellets, the basic mechanical properties were determined – mechanical durability, wettability index and hardness. The experiments were performed in a batch dosing reactor at the process temperature of 500°C. The results show that highest conversion rate of input material into the final products of the pyrolysis process was achieved by using the standard pellets. The achieved outputs are used for research of input materials pre-treatment and for optimization of process parameters of thermal degradation during the energy utilization of grass biomass.
