The pyrolysis of biomass is a promising route for the production of solid (charcoal), liquid (tar and other organics), and gaseous products. These products are of interest as they are possible alternate sources of fuels and chemicals. The most interesting temperature range for the production of the pyrolysis products is between 625 and 775 K. The charcoal yield decreases as the temperature increases. Liquid products from biomass pyrolysis are maximum at temperatures between 625 and 725 K.
