Spectroscopy and Asphaltene Structure

  • James G. Speight

Abstract

The spectroscopic (and chemical) methods used to determine the “structure” of petroleum asphaltenes, coal and coal asphaltenes have added valuable information about the character of these materials. Nevertheless, attempts to be too literal in the interpretation of the data and the continued insistence that these complex materials have a well-defined molecular structure is of questionable value to fossil fuel technology and is certainly beyond the scope of the available methods to derive such a formula. In fact, petroleum, coal and coal asphaltenes would best be described in terms of several structural types rather than definite molecular structures.
