本文用顺磁共振谱研究了广东南岭烟煤和梅田无烟煤在热解过程中自由基浓度和谱线宽度的变化,指出磁黄铁矿(Fe_(1-x)S)对煤中自由基的形成无任何影响,而黄铁矿(FeS_2)则有明显的催化作用。
In this paper, the changes of free radical concentration and spectral width of anthracite in Nanling bituminous coal and Umeda coal in Guangdong were studied by means of paramagnetic resonance spectroscopy. It is pointed out that the influence of pyrite (Fe-1-x S) The formation of any effect, and pyrite (FeS_2) has a significant catalytic effect.
