Abstract
The purpose of this study is to establish the basic technology to achieve CO_2 reduction and hydrogen production by using exhaust gas, waste steam, and chaffs. We used the chaffs with mean particle diameter of 20 and 100μm, and applied shock heating technique by the shock wave driven by high pressure helium. The experimental apparatus is a standard shock tube having inner diameter of 100mm. We found that hydrogen concentration increases gradually with increase of temperature. The highest hydrogen concentration was about 30%. The shock heating temperature for acquiring the value of high hydrogen concentration was about 1000〜1300K. By using the mixing chaffs(average particle diameter of 20μm and 100μm), hydrogen concentration higher than the case where average particle diameter is 20μm was obtained.
