Performance of Methane Steam Reforming in Internal Spiral Finned Tube

Methane steam reforming is an important method of hydrogen production. In this study, the performance of methane steam reforming in internal spiral fin structure reactors through the equivalent medium method has been investigated. The efficiencies of different structure reactors have been compared in same boundary conditions. It is found that internal spiral fin structure reactors can improve the efficiency of methane steam reforming. Methane conversion rate of the structure S40 increased by up to 2% compared with the structure Normal. Hydrogen production rate of the structure S40 increased by up to 0.3% compared with the structure Normal.
