An integrated in situ combustion process for recovering subterranean liquid and solid carbonaceous deposits in which the resulting flue gas of low heating value is combusted at substoichiometric conditions over two different oxidation catalysts in two combustion zones in series and is expanded in a gas turbine which drives the air compressor for injecting the combustion air into the underground carbonaceous deposit. One of the oxidation catalysts comprising platinum and at least one metal cocatalyst selected from Groups IIA and VIIB, Group VIII up through atomic No. 45, the lanthanides, chromium, zinc, silver, tin and antimony is provided to reduce the carbon monoxide in the combusted flue gas.
