Introduction to Coal Photochemistrylecules and even small particles. Consequently, despite their aromaticity, such materials do not give ultraviolet absorption spectra, rather they scatter light. Information about the chemistry of the aromatic nuclei can be obtained, however, from the fluorescence of extracts, notably from their exci

Coal Characterization by Means of Curie-Point Pyrolysis Techniquesix coal samples, representative for the entire range of coal ranks, were selected from the set of 40 coals to study the pyrolysis product mixtures as a function of the coal rank in more detail by Curie-point pyrolysis gas chromatographic techniques (PyGC and PyGCMS). PyMS revealed that the number an

Slow and Rapid Pyrolysis of Coals is the most important aspect of coal behaviour because it occurs in all major coal conversion processes. Upon pyrolysis coal is divided into a hydrogen-rich volatile fraction, consisting of gases, vapors, and tar-components, and a carbon-rich solid residue. Moreover, for certain coals decompositio

Coal Desulfurization. The Protodesulfurization of Naphthalene Thiols and Sulfidescleophilic replacement of sulfur by oxygen in aryl thiols and sulfides led to the discovery of an acid-catalyzed reductive desulfurization reaction that proceeds readily under surprisingly mild conditions. Specifically, the treatment of 1- and 2-naphthalenethiol, 1- and 2-naphthyl alkyl sulfides, an
