摘要：

Selective reduction of nitric oxide with methane or ethane in the presence of excess oxygen was investigated using a gallium ion-exchanged ZSM-5 zeolite catalyst(Ga-ZSM-5). Ga-ZSM-5 was highly active and selective for NO reduction above 400-degrees-C. The limiting molar ratios of reacted NO to consumed carbon in C2H6 and CH4 at 500-degrees-C were found to be 1.5 and 2, respectively.
