Abstract
The purpose of the present study is to establish the basic technology to achieve the CO_2 reduction and the hydrogen production by using exhaust gas, waste steam, and sawdust. As the method, we used shock heating by the gas shock waves driven from high pressure gas. The experimental apparatus is standard shock tube. As a result, hydrogen concentration increased by getting small size and adding the sawdust and rising the shock heating temperature. The highest hydrogen concentration is about 30%. The particle diameter of the sawdust should be adjusted a decrease of CO_2 and a high hydrogen concentration to about 30% or less, and the shock heating temperature be adjusted to about 1200K or more.
