A membrane reformer is composed of a steam reformer equipped with palladium-based alloy membrane modules and can perform steam reforming reaction of natural gas and hydrogen separation processes simultaneously, without shift converters and purification systems. We have developed a membrane reformer system with nominal hydrogen production capacity of 40 Nm(3)/h. The system has demonstrated the potential advantages of the membrane reformer: simple system configuration as benefited by single-step production of high-purity hydrogen (99.999% level), compactness, and high-energy efficiency of 70-76%. We are promoting development towards commercialization of the membrane reformer technology, focusing on further improvement of energy efficiency, proof of long-term durability and reliability, and establishment of system engineering technologies. The target of our current project is to develop a membrane reformer system that can produce 99.99% or higher-purity hydrogen from natural gas at a rate of 40 Nm(3)/h with hydrogen production energy efficiency of over 80%.
