IDEA #73TQI3 Production Of Pyrolysis Oil From Biomass

APPLIED RESEARCH • ENERGYAND ENVIRONMENTAL RESEARCH PRODUCTION OOFF PYROLYSIS OIL FROM BIOMASS Description Fast pyrolysis of biomass is widely used for bio(cid:2)oil (pyrolysis oil) production. Bio(cid:2)oil can be applied as a fuel in boilers, diesel engines and gas turbines. Fast pyrolysis technology on the basis of ablative reactor of a new type (screw reactor) has been developed. In the reactor particles of raw material are under heating and ablative influ(cid:2) ence (ablation) due to squeezing and rubbing against the body of the reactor. These two factors insure optimal parameters of the process for high yield of liquid bio(cid:2)fuel. Innovative Aspects and Main Advantages Developed technology is simpler than some other existing fast pyrolysis technologies (circulating fluid bed, circulating trans(cid:2) ported bed). Developed screw reactor can operate on a raw material with rather big particles. Proposed technology gives a very high yield of pyrolysis oil (up to 70% of biomass supplied to the reactor). Produced pyrolysis oil is expected to have lower content of water in comparison with other pyrolysis tech(cid:2) nologies. Proposed technology gives the opportunity to create both stationary and mobile pyrolysis units. Fast pyrolysis tech(cid:2) nology on the basis of ablative reactor of a new type practical(cid:2) ly does not pollute environment with products of cleaning(cid:2)up. Area ooff Application Pyrolysis unit can be applied in rural areas where biomass such as agricultural residues or wood waste is available to be used as raw material for bio(cid:2)oil production.

Draft design of a 15 kg/hr pilot unit is developed.
