Oil/sand sample was subjected to a linear heating program 5oC/min from room temperature to a set point temperature 400oC under continuous flowing of air 250 ml/min on a low pressure 3 bar. Combustion gases produced were allowed to flow to a condenser and further were flowed through a drierite bed prior to measure by a GC continuously. Combustion gases produced and oxygen consumption profiles were confirmed that the combustion process has been successfully conducted during experiments. A lighter oil of 23.3oAPI was produced from the catalytic run compared with oil of 19.3oAPI resulted from the non-catalytic run.enIn situ combustionheavy oilcatalystthermal and catalytic processescombustion gases producedUR-Proceedings
