文摘
In this research, sixteen experiments were conducted to study the combustion reaction kineticsof Turkish crude oils (Bati Raman, Çamurlu, Raman, Adiyaman, Garzan, Karaku
, and Beykan)in a limestone medium. A mixture of the limestone and the crude oil was subjected to a controlledheating program under a constant flow rate of air. The produced gas was analyzed for its oxygenand carbon oxides contents. Although the molar CO2/CO ratios vary during low-temperatureoxidation (LTO), for fuel deposition (FD) and high-temperature oxidation (HTO), these valuescan be indicated at different temperatures. A decrease in the atomic H/C ratio with an increasein temperature was observed for all runs. The activation energies of the Çamurlu, Bati Raman,and Raman crude oils for both fuel deposition and high-temperature oxidation reactions wereobserved to be similar. For medium-gravity oils (Adiyaman and Garzan), the activation energiesfor the high-temperature oxidation reaction is higher than that for the fuel deposition reaction.For the LTO reaction, the activation energies are almost twice those of FD and HTO reactionsfor each crude oil. The activation energies are almost independent of the gravity of the oil used.The Arrhenius constant is not affected by the API gravity of the oils.
