Economic Assessment of Pyrolyzers for the Utilization of Agricoltural Residues for Biooil Production

The agricultural residues and in particular the straw, can represent an important energy source in the world, but is today in great part unutilised. The utilization of straw for energy production is neutral for a carbony-dioxide formation and also it can gain more independence the nation from the oil importation. Unfortunaly the straw property is different from crude oil products. Infact it presents a relativity low volumetric energy content, bad transportability and difficult in use. The principal barrier is the expenses associated with logistics (e.g. bailing, storage and transport). Also the uninterrupt supply of fuel is of importance to energy consumers and accordingly expenses arising from long transport of straw make unself less competive with fossil fuels under free market conditions. Due to the above factors a way to make competitive the straw derived energy would be the thermical conversion to an attractive energy product in the field and the transport of this product to an electric power station, for example.
