The purpose of this study is to develop the technique to Bio-fuel by a shock wave using exhaust steam. In the first step, we used rice straw with mean particle diameter of 35 urn and investigated on the hydrogen and the carbon monoxide concentration using the shock wave induced by high pressure helium. In this study, we paid attention to the effect of the temperature and the moisture on the Bio-fuel. As a result, we obtained 44% of the highest hydrogen concentration in 1700K. And, 'we found that the temperature and the moisture are important parameters in Bio-fuel production using rice straw.
