✦ Synopsis

In-situ combustion is a thermal recovery method applicable to heavy oil locations. The thermal energy released by partial burning ofthe crude oil is significant in the displacement of the remaining oil. During an underground combustion process, exothermic oxidation reactions involving oxygen and hydrocarbons of various H/C ratios lead to a wide variety of reaction intermediates and reaction products. Combustion reactions that take place > 3WC, with CO,, CO and H,O as the principal reaction products, are generally referred to as hightemperature oxidation (HTO) reactions.

Lowtemperature oxidation (LTO) reactions occur in zones where the temperature is < 300°C. In the latter case, water and oxygen-containing compounds such as carboxylic acids, aldehydes, ketones, alcohols and hydroperoxides are known products.

Hydrocracking of Athabasca bitumen was studied in a batch reactor at 620-693 K and at an initial hydrogen pressure of 7.2 MPa (at 293 K). The reaction products were separated into coke, asphaltenes, resins, aromatics, saturates and gases. The reaction time versus product yield curves were obtained f
