The study of solid residues after biomass pyrolysis

Abstract

Biomass pyrolysis is commonly used to produce alternative energy, fuel and chemical raw materials. In this
scientific article was investigated the solid residue of the biomass pyrolysis process. Sawdust of pine tree was used as raw
material. Pyrolysis was carried out at 500 oC and 800 oC degrees in a nitrogen stream of 1 l / min. Indicators of the solid
residue characteristics were identified by conducting a technical analysis. The surface topography of each obtained sample was
examined by a scanning electron microscope (SEM). Detection of the functional groups of the solid residue was accomplished
by the method of infrared - Fourier spectroscopy (IR-Fourier). The experimental results were analyzed including chemical and
physical properties of the solid residue. The given study is still under thorough investigation.
