Abstract

Pyrolysis oil is a new type of fuel from biomass which presents significant potential for the CO2-free power and heat generation. Typically during pyrolysis process, 60 – 75 wt. % of the feedstock is converted into pyrolysis oil. The remaining mass is converted to char and non-condensable gases which are combusted and reused for pyrolysis process, biomass drying, heat and power generation. Only few percent of energy is lost in the form of heat. Since the pyrolysis oil is biomass in liquid form it can be easily transported to a place of destination. It can be also stored to cover shortage in electricity or heat during the day or in emergency situation. High energy density, by factor 5-20 higher than the feedstock from which pyrolysis oil is produced, promotes it over conventional biomass. Furthermore, pyrolysis oil does not compete or interfere food chain (second generation of biofuels) and the minerals left from the pyrolysis oil production might be re-used for soil enrichment.
