there are three final products of the pyrolysis process:
a) Solid carbon-containing residue (carbonization product), chiefly consisting of elemental carbon, unreacted organic compounds, and solid particles. The carbonization product may be utilized as a solid fuel granulated with another biomass type, as a raw material for the production of activated carbon, as a raw material for the generation of hydrogenrich
gas by gasification, or as a raw material for the production of catalysts with high specific surface area.
b) Pyrolytic oil (bio-oil), which is a mixture of organic and inorganic compounds and consists of a water fraction and an oil fraction. Pyrolytic oils contain carboxylic acids, alcohols, phenols, esters, aldehydes, ketones, and heterocyclic oxygen compounds. The water contained in the bio-oil chiefly comes from moisture content of the material, but
may also be a product of the dehydration reaction that takes place during the pyrolysis process; therefore, the water content may vary within a wide range depending on the feedstock material and process conditions. The water fraction may contain acetic acid and phenols.
