MODELING AS FUNCTION OF TEMPERATURE OF VISCOSITY AND DENSITY FOR BLENDS OF DIESEL FUEL AND THERMALLY DEGRADED POLYETHYLENE

George Liviu POPESCU

Abstract


The paper presents the mathematical modelling of dynamic viscosity, kinematic viscosity and density as a function of temperature for a series of binary blends between the commercial diesel fuel (CDF) and a fuel obtained by thermal degradation of Low Density Polyethylene (LDPE). The values for viscosities and density were calculated starting from the measured values for CDF and LDPE fuel as a function of temperature. The Gas Chromatography coupled with Mass Spectroscopy (GC-MS) has been used for the determination of the composition of the fuel obtained by thermal degradation of LDPE. Based on the data obtained by GC-MS the molecular weight of the fuel obtained by pyrolysis of LDPE has been calculated and the mole fraction of each component.


Key words: recycling, fuel, modelling, viscosity, density.
