摘要：

Combustion tube experiments were carried out under various conditions to investigate the performance of catalytic in-situ combustion for recovering heavy oil. Compared with baseline experiment, the catalytic combustion exhibited better performance. Fractional oxygen gas in effluent gases was reduced by 2.9%, while fractional carbon dioxide and carbon monoxide was increased by 1.0% and 0.6%, respectively. Oxygen utilization efficiency was increased by 2.1% and apparent H/C atom ratio was lowered by 0.9%. The combustion performance was obtained under optimum experimental condition of air injection rate of 2.9mL/min, preheated temperature of 190 degrees C, and grain-size gradation 2.
