摘要：

High resolution X-ray absorption spectroscopy utilizing synchrotron radiation as a light source was used to probe the bonding and structure of potassium in coal and coal-derived products. The potassium sites in coals of various ranks and in the products of thermochemical processing were identified by comparison of unknown spectra with those of a wide range of selected potassium model compounds and minerals. For most coals examined, potassium was found to occur in a site in illite, a layered clay related to muscovite. Such coals included subbutuminous, high and low volatile bituminous, cannel and anthracite types.
