The project was focused on the thermochemical conversion of waste lignocellulosic biomass – sunflower seed shells, by investigating different ratios of biomass and ZSM-5 catalyst in CO2 and N2 pyrolysis environments. Sunflower seed shells are an abundant waste of the edible oil industry, which can be converted to bio-oil as an energy product via a catalytic pyrolysis process. The project aimed to determine under which process conditions the bio-oil of the highest quality is produced. The quality of the bio-oil formed on a small scale was evaluated according to the formation of energetically valuable products during the catalytic pyrolysis of biomass employing gas chromatography and FTIR spectroscopy analysis methods. Conclusions were drawn as to how the concentration of the ZSM-5 catalyst and the pyrolysis environment affect the formation of energetically valuable products from biomass during pyrolysis.
