HIGH-PRESSURE DSC APPLICATIONS ON CRUDE-OIL COMBUSTION

A pressurized differential scanning calorimeter (PDSC) has been used t o obtain information on the combustion characteristics of crude oils a nd their mixtures in two chemically different matrix materials, sand a nd limestone. Crude oil and sand-limestone mixtures were prepared to g ive a composition of 10 wt % crude oil in matrix. The PDSC curve clear ly demonstrates two distinct transitional stages, namely combustion of liquid hydrocarbons and combustion of coke. The kinetic part of this research is concerned with only one peak, namely the coke combustion. Kinetic data were analyzed by two different kinetic models and the res ults are discussed.
