Experimental Determination of Heat of Combustion Values, Viscosity, Surface Tension and Density for Different Jet Fuel and 2-Propanol Blending

In the present study, various samples of jet fuel blended with 2-propanol have been prepared in different ratios. All the samples were used for the determination of heat of combustion (∆H_c, MJ/kg), and only one blending sample was chosen for determining the surface tension (σ, N/m), viscosity (µ, mmPa.s) and density (kg/m³) values using different analytical instruments. We measured surface tension, viscosity and density and did comparison with pure jet fuel properties. Heat of combustion was measured using bomb calorimeter, surface tension was measured using stalagmometer, viscosity was measured using rotational viscometer, and density was measured using digital electronic weighing balance. All the obtained data are discussed in the form of table and graphs in the article. From the obtained results, it was observed that binary blending of jet fuel and 10% (by weight) 2-propanol is better in terms of heat of combustion values and may be utilized as alternative fuel. Some catalysts were also added in the fuels samples, but the results were not very encouraging. However, these catalysts can be used in nano-form or in gelled fuels for better results.
