ALTERTIVE JET FEUL FROM HYDROISOMERIZATION OF COAL-BASED FISCHER-TROPSCH MIDDLE DISTILLATES

摘要

Recently, there has been urgent requirement in the development of alternative fuels for aviation applications considering the growing shortage in the international oil supply and increasing concern on global environment. Fischer-Tropsch process provides the ability to convert syngas (from coal, natural gas, and biomass) into a cleaner and more economical alternative fuel. In 2008, the jet fuel specifications have been modified (MIL-DTL-83133F) to allow Synthetic Paraffinic Kerosene (SPK) derived from a Fischer-Tropsch process as a blend stock. The key properties of such a fuel is a maximum freezing point of -47°C, a minimum flash point of 38°C, a minimum density of 0.751kg/L at 15°C and a maximum viscosity of 8 mm~2/s at -20 °C.
