摘要：
The electron paramagnetic resonance (EPR) method was used to characterize samples of activated coal before and after reactions of the catalytic decomposition of methane and ethanol at temperatures of 1023 K (750 degrees C), 1123 K (850 degrees C) and 1223 K (950 degrees C). The EPR parameters: spectroscopic splitting factor g, peak-to-peak linewidth Delta B-pp, and spin concentration c were measured. During the ethanol-assisted catalytic decomposition of methane carbon-located-spin radicals are partially transformed into oxygen-located-spin radicals.
