Nutuna Island Indonesia has one of the largest deposits of natural gas in the world. However, the Nutuna gas contains a large fraction of carbon dioxide of around 70%. Previous research has shown a combustion promotion effect by adding hydrogen to the gas in a spark-ignition internal combustion engine. The hydrogen addition by 20% in volume was sufficient for improving thermal efficiency and power output at stoichiometric mixture condition. This paper experimentally analyzes fundamental characteristics of the Nutuna gas reforming to produce hydrogen at different initial temperatures. Effects of oxygen and steam on dry reforming of the gas are also discussed.
