CARBONIZATION OF FORESTAL AGRICULTURAL AND AGRO-INDUSTRIAL WASTE AS WELL AS OF ORGANIC MUNICIPAL WASTE AND PRACTICAL UTILIZATION OF THE RECOVERED PRODUCTS (CHARCOAL, GAS, PYROLYSIS OIL)
We selected biomasses with very different physical and chemical structures (soft wood bark, wheat straw, olive residues, grape residues and rice husks); continuous carbonization plants are found to achieve an energy yield of at least 80 % of the energy content of the processed biomass. The various biomasses and the energy carriers produced were thoroughly analyzed (quantity and energy yield, physical structure, chemical composition, etc.). Tests for using charcoal briquets, granulates, extrudates (made from char plus various binders) as domestic fuel, fuel for gas generators and basic material for the production of activated carbon were successful. A 1:1 pyrolysis oil - fuel oil mixture can be used, without fractioning, by conventional burners. Tests for the utilization of pyrolysis oil in a newly developed diesel engine met with problems; nevertheless, we achieved first successes both with 1:1 mixture of pyrolysis oil and castor oil and with pure pyrolysis oil. On balance, the investigations and tests confirm that the carbonization technique is well suited to transform basically all solid and dry biomasses, independent of their partly into high grade transportable energy carriers which can be used energetically by known techniques.
