20-75 DETERMINAREA CARACTERISTICILOR FIZICOCHIMICE ALE BIOCOMBUSTIBILILOR PE BAZĂ DE ULEI ALIMENTAR UZAT, ÎN AMESTEC CU MOTORINA
THE DETERMINATION OF THE PHYSICO-CHEMICAL
BIOFUEL WHITH FUEL BASED OF USED COOKING OIL IN
COMBINED WITH DIESEL
Mentioning that low caloric power of biofuel based of used cooking oil
(36867 kJ/kg) is inferior to diesel (41800 kJ/kg) it was trying partial replace of
diesel with monoester from used cooking oil regarding the mainteining of the
engine power concomitent with the drop of the polluants from exaust gases.
Folowing this, after the fabrication and setting up of the optim recepy of biofuel
from used cooking oil, it was done the mix of biofuel and diesel, in different
proportion, wich are label related to basic material, beeing experimental
determinated the densieties and cinemati viscocieties of new fuels, compared
with diesel, at temperatures between 580 0C. It was detected a growing of
density and viscosity of fuel based of used cooking oil compared with diesel
around 3,148 % and 26,44 % on the whole scale of trying temperatures.
