Production of bio-oils: physical and energy technical properties

The aims of this research are to find, in decentralized production, more economical and effective techniques based on sustainable energy to extract and transesterificate oil to fuel (the use of ethanol, catalysts, and so on), to find new more effective filtering techniques to clean oils and fats for diesel fuel that produces less pollutants, verified by engine experiments, to find optimal regulations and design parameters for engines using biodiesel, to obtain real-life and laboratory test results on performance and emissions with cars and larger engines, to be able to make tests and applied research that smallscale industry and oil producers need, and to be able to produce technical information about oil extracting and transesterification processes. Some preliminary results of optimizing the seed pressing process are published here. Very first diesel engine results obtained with animal fat based biodiesel are also presented, and compared with those of rape seed methyl ester. Animal fat based bio-fuel was produced by the transesterification technique.
