Abstract:
A process for preparing the Ga2O3-Al2O3 catalyst used in reduction of Nox includes such steps as preparing gallium nitrate from gallium oxide, preparing monohydrated bohmite by sol-gel method, mixing gallium nitrate with ethanediol, adding the mixture to monohydrated bohmite, vacuum distilling, drying and calcining. Its advantages are low cost, high specific surface area and activity, and high reducing rate as high as to 70-85%.
