The development of a kinetic model of the in situ combustion process from data obtained from thermogravimetric analysis (TGA) and differential scanning calorimetry (DCS) is described. The kinetic model was used to predict fuel deposition and combustion rate in a combustion tube. Good agreement was obtained between predicted and observed fuel deposition and combustion rate in 2 combustion tube runs. Data from TGA experiments on Iola County, Kans., crude heated in the presence of air were obtained. Analysis of combustion gases from the TGA was done by gas chromatography to determine the nature of the reactions occurring during the TGA runs. Main reactions/transitions identified were distillation, low temperature oxidation, cracking and combustion. A kinetic model of the TGA process was developed for thermograms. The model is based on the weight of crude oil components which undergo main reactions/transitions. 26 references.
