Pyrolysis is widely used as a biomass conversion technology to obtain bio-fuel. It is also an interesting technology at an industrial scale, which is a motivation to seek an increase in process efficiency. The pyrolysis of large biomass particles differs from the pyrolysis of fine particles because it cannot be considered to heat up and decompose homogeneously. In this work, experimental data for the pyrolysis of a wheat straw pellet and a single particle model are presented. Furthermore, the key parameters controlling the internal temperature distribution are discussed.
