Abstract

Catalytic performance for NOx removal by Ga-incorporated silicates(Ga-silicate; Gallosilicate) with MFI type synthesized by the rapid crystallization method was reported in this study. NOx removal was investigated under the condition of O2 excess(10%), with various hydrocarbons of low concentrations. Effect of H2O(2%) addition was also considered. The result showd that the conversion from NOx to N2 was enhanced on the Ga-silicate compared with the Al-silicate. Furthermore, the performance for NOx conversion on the Ga-silicate increased with addition of water.
