The Performance Study of Aviation Fuel Added with Alcohols

Alcohols ranging from C2 to C8 are added to RP-3 jet kerosene to alleviate the pollution when fuel burns. Such mixed fuels are tested in respects of density, viscosity, heat value, rubber compatibility, silver corrosion and copper corrosion. The results show that fuel mixed with n-pentanol resembles RP-3 kerosene best and fuels mixed with ethanol, propanol and n-butanol perform inferior than other mixed fuels in the test for compatibility with rubber. All seven fuels perform well for the test in silver corrosion and copper corrosion. The result for the fuel mixed with ethanol lies slightly behind others in copper corrosion.
