Research Abstract

Copper oxide is one of the suitable materials for oxygen carrier because reduction of CuO by carbon is exothermic reaction which benefits energy balance in the proposed hydrogen production process. The result of thermogravimetry test using dry mixtures of copper oxide and graphite showed rapid weight change at around 600℃. Hydrogen production from graphite was confirmed at around 600℃ by the gasification test in combination with Lithium Silicate used as CO_2 sorbent under the condition of various C/CuO mixture ratio and steam mass flow, and this result showed reaction promotion effect derived from non-equilibrium state by CO_2 absorption.
