Influence of temperature and heating rate on biomass pyrolysis in a fixed-bed reactor

Biomass is one of the renewable energy resources with near zero C0₂ emissions; consequently much research has been investigated in order to replace conventional fossil fuels with biomass in energy conversion sector. Pyrolysis is a thermo-chemical conversion for the production of char, oil and gas products and it is also the initial step for other important thermo-chemical conversion processes like combustion and gasification. This paper focuses on the effects of operating parameters (pyrolysis temperature and heating rate) on pyrolysis product distribution. Therefore 178 experiments were conducted in a lab scale fixed-bed reactor at different temperatures and heating rates for differnet types of biomasses. The experiments were carried out for several types of biomass: spruce wood (SPW), corn stalks (CST), wheat straw (WST) and sawdust (SWD), meaning 58 experiments.
