A commercial activated carbon was treated in nitrogen flow using a microwave device as heat source. The effect of microwave treatment of activated carbon on its composition, structure and texture, as well as ruthenium dispersion on it was investigated by elemental analysis, X ray diffraction, N 2 physisorption and CO chemisorption. It was found that the microwave treatment of activated carbon can eliminate carbon impurities, improve the stability of activated carbon support under the ammonia synthesis con...
