ABSTRACT:
A process for operating a compression ignition internal combustion engine in combination with a catalytic partial oxidation reformer and, optionally, an exhaust gas aftertreater, wherein:(a) a mixture of a first fuel and air, wherein the first fuel comprises Fischer-Tropsch derived fuel, is introduced in the combustion chamber of the engine;(b) exhaust gas is discharged from the engine and optionally partly recirculated to the combustion chamber of the engine;(c) a second fuel and oxygen and/or steam are supplied to the catalytic partial oxidation reformer to produce synthesis gas, wherein the second fuel comprises Fischer-Tropsch derived fuel;(d) at least part of the synthesis gas is supplied to:(i) the exhaust gas aftertreater;(ii) the combustion chamber of the engine; or to both.
