Application of Cold Gas Dynamic Spraying in Methanol Steam Reforming for Hydrogen Production

Copper coating on aluminum substrate was prepared by cold gas dynamic spraying for hydrogen production through methanol steam reforming.SEM and EDS analysis of the coating before and after methanol steam reforming reaction were carried out.The results show that,after the reforming reaction oxygen and aluminum elements content of the coating increased,the coating morphology changed from piled sheets structure to micro-ramified structure,its porosity obviously increased and the H2 content in the reformate reached 74.9% indicating that the catalytic coating can be prepared by cold gas dynamic spraying.
