14.石炭中に存在する硫黄種のXANESによる同定

抄録

X-ray absorption near edge structure (XANES) was applied to the direct determination of the chemical and structural environment of sulfur in coals. Third derivatives of the XANES spectra from model compounds provided fingerprints for interpreting sulfur forms in coals. XANES analysis indicated that high rank Fu Rong coal have elemental sulfur, which explain the high desulfurization.
