  • 摘要: 利用XPS技术研究了贵定煤和西班牙Mequienza煤中硫和氮化学形态的分布,并结合流K-边XANES和Mossbauer谱着重考察贵定煤中硫化学形态.结果表明,贵定煤中含硫化合物主要以噻吩形态存在,其次为有机硫化物;而Mequienza煤中以有机硫化物含量最大,噻吩硫次之.有关含氮化合物,Mequienza煤以吡咯和吡啶氮为主,但在贵定煤中观察到较大浓度的氧化氮化合物.
    Abstract: The chemical forms of sulfur and nitrogen in Chinese Guiding coal and Spanish Mequinenza coal were studied using XPS method,combining with sulfur K-edge XANES and Mossbauer spectroscopy to pay special attention to the sulfur forms in Guiding coal. The results indicated that thiophenic sulfur is the most abundant form followed by organic sulfide in Guiding coal,and that organic sulfide is more dominant than tniophenic sulfur in Mequinenza coal. For the nitrogen forms, pyrrolic and pyridinic nitrogen are main forms in Mequinenza coal,but high level of N-oxide was observed in Guiding coal.
