This study on methane reforming suggests a new method using partial oxidation compression ignition reformer where the concept of super-adiabatic combustion is applied. In this research, optimum condition for producing hydrogen from methane, which is the main component of biogas, using a compression ignition reformer, is studied as a basic approach for producing synthetic gas from biogas. For compression ignition reformer using partial oxidation reaction, an unmodified compressed ignition internal combustion engine is used. The experiment is carried out using enriched oxygen by adding oxygen, which is oxidant, to expand the limit of inflammability range so that the engine could be operated even at the fuel -rich. The oxygen/fuel ratio (oxygen enrichment rate), total flow rate and intake preheating temperature were used as experiment variables. When oxygen/fuel ratio (oxygen enrichment rate: 77.2 %) is 1.24, total flow rate is 208.4 L/min and intake preheating temperature is 400 ℃, the maximum hydrogen concentration obtained was 29.22, 26.93 and 23.53 % respectively.
