“…Yoshiki and Phillips (1985) presented the following expressions for calculating kinetic parameters from the DTA data. These expressions are applicable to cylindrical cells and were obtained by modifying the original expressions presented by Bae (1972) for spherical cells. The relevant equations for an nti order reaction are listed below.…”

“…At high temperature, the oil remaining in the porous medium cracks into a volatile fraction and a nonvolatile carbon rich hydrogen poor residue often referred to as “coke”, which is the actual fuel for combustion. Many laboratory studies − demonstrated the range of fuel consumption from 13 to 45 kg/m 3 . Based on the oxygen gas consumption and the combustion front velocity, the fuel consumption can be calculated, the maximum of which was 28.99 kg/m 3 in this case.…”

Laboratory in situ combustion experiments were performed to determine the basic parameters prior to field projects, using a self-made combustion tube and S1-38-330 crude oil from Liaohe Oilfield. These basic parameters, the oil’s ignition temperature range from 340 to 360 °C, the apparent atomic H/C ratio of 1.044, the oxygen utilization of 52.15%, the oil recovery factor of 78.6%, the combustion front movement velocity of 0.20 cm/min, the maximum fuel consumption of 28.99 kg/m3, and the maximum air requirement of 298.6 N m3/m3, etc., were determined in the experiments. The gas chromatograms showed that the crude oil had undergone a series of pyrolysis reactions during combustion, and it could also be proved via the results of aromatics mass spectrometry that anthracene was generated during this process.

The thermal analysis technique was used to rapidly evaluate the compatibility of explosives with contacted materials. The three kinetic parameters viz. activation energy E, reaction order n and pre‐exponential factor A were calculated from three characteristic temperatures of a single DTA curve. The compatibility was evaluated from the four parameters E, n and the characteristic temperatures Tm (peak maximum) and To (decomposition starting point on the DTA curve). The results are compared to those obtained from the gasometric method.
