Slow pyrolysis of wood
WebbSlow pyrolysis In general, the aim of the slow pyrolysis process with a relatively low heating rate (0.1 to 1 °C/s) is the production of high-yield biochar (10 to 90%) from biomass. The reaction is usually carried out in an operating temperature range of 300 to 700 °C and a wide range of residence time (from several hours to days) (Li et al. 2024). Webbproducts as a function of temperature for use in gasification and wood combustion models, where the pyrolysis process is slow. For modeling of thermal degradation of …
