The identification and quantification of the nitrogen functions in coal and coal-derived liquids is important for the development of coal liquid-fuel processing technologies. This paper reports a method that provides a self-consistent analysis of nitrogen functionality in both solid coal and coal li

The organic molecules which make up coal are held together not only by covalent bonds, but also by a substantial network of hydrogen bonds as well as certain other weak intermolecular associations, which together are called the secondary structure. It is believed that acidic hydroxyl groups are res

The acute toxicity of a series of potential streams from the EDS coal liquefaction process have been assessed in animal bioassays. In general, the materials present minimal acute toxic hazards. However, there was some evidence of ocular and dermal irritation. These results indicate that eye and derm
