Combustion characteristics of asphaltites
In this research, a laboratory work is performed to observe the combustion characteristics and reaction kinetic's of Silopi region asphaltites. A total of twelve experiments were performed with two different mesh sizes and under three different pressures. Product gas analyses were used to determine atomic H/C ratio, relative reaction rate, activation energy and Arrhenius constant for each asphaltite sample studied. The relative reaction rate vs. inverse temperature plots of Silopi asphaltite showed two main reactivity regions. One is occurring in the low temperature region and the other is in the high temperature region. In the low temperature region, an early production was observed where the volatiles within the asphaltite were released; remaining heavy hydrocarbons caused the formation of the second, high temperature region.
