Calorimetric Determination of Energy Content of Alcohol fuels and Blends with Kerosene
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 2
Abstract
In this research we explored the calorific or heat value of alcohol fuels as well as blends with kerosene by using both glass and bomb calorimeters comparatively. The calorific values obtained from the combustion of alcohol fuels from glass calorimeter were very much lower than those obtained from bomb calorimeter, as a result of heat loss in glass calorimer. The heat values, obtained by glass calorimeter, of methanol, ethanol, propanol, butanol, and pentanol gave 6.3MJ/Kg, 10.64MJ/Kg, 15.27MJ/Kg, 20.84MJ/Kg, and 22.56MJ/Kg respectively, while the heat values of methanol, ethanol, propanol, butanol, and pentanol, using the bomb calorimeter gave 16.36MJ/kg, 21.6MJ/Kg, 30.75MJ/Kg, 32.13MJ/Kg, and 36.1MJ/Kg respectively. It is observed that the heat value of each blend is greater as the percent of alcohol increases, but as the percent alcohol exceeds the percent kerosene, the heat value starts to decrease. Generally, the heating values of alcohol fuels increase as the carbon atoms increases and the heating values of these alcohol fuels increase as the percent oxygen decreases
