Preparation of metal catalyst component doped perovskite catalyst particle for steam reforming process by chemical solution deposition with partial reduction

Co-doped LaAlO3 nanoparticles with partial reduction were applied as a catalyst to ethanol steam reforming. Co-doped LaAlO3 nanoparticles were prepared using chemical solution deposition. The Co component was generated on the nanoparticle surface by a partial reduction process. The estimated H2 yield of the ethanol steam reforming process was changed by altering the reduction conditions, although the surface areas of the reduced nanoparticles were almost equal. The highest H2 yield was attained at 948 K reduction temperature. The calculated H2 yield and the conversion ratio were, respectively, 78% and 99%. Reaction bi-products during steam reforming were measured to elucidate the change of the H2 yield with the reduction temperature.
