Development of metal-honeycomb-type structured catalyst system contributing to an advanced progression of hydrogen production

为了构建一种新型的制氢体系，采用溶胶-凝胶法和化学镀相结合的技术在不锈钢基体上构建了一种蜂窝状镍基催化剂体系.该体系具有较高的甲烷水蒸气重整性能和接近平衡转化率的产氢能力。同时，还构建了与催化燃烧相结合的多功能重整系统。该组合重整系统通过传导传热将热能快速供给反应区，大大提高了制氢能力。

In order to construct a novel hydrogen production system, a honeycomb-type nickel-based catalyst systemwas constructed by a combination technique consisting of a sol-gel method and an electroless plating on a stainless steel substrate. The constructed system demonstrated high reforming property of methane steam reforming and high hydrogen production ability close to the equilibrium conversion. The multifunctional reforming system, which combined with a catalytic combustion through the reactor wall, was also constructed. This combined reforming system enabled a rapid supply of thermal energy to reactive zone by conductive heat transfer and produced an improvement of a great advance of hydrogen production ability.
