Current status of FTIR in the analysis of coal structure
- Penn State Univ., University Park, PA (United States)
Infrared spectroscopy has been a basic {open_quotes}workhorse{close_quotes} technique for coal characterization since the pioneering work of Brown nearly 40 years ago. The optical and data handling advantages of MR have allowed various advances, such as the introduction of {open_quotes}hyphenated{close_quotes} techniques (GC-FTIR, IR-Microscopy, etc.) and novel sampling methods (diffuse reflection, photo-acoustic measurement, etc.), but most of the problems in coal structural analysis remain the same; the quantitative determination of various functional groups in coal and how the concentration of these groups varies with, for example, oxidation or liquefaction. In a short article of this type justice cannot be done to the range and scope of work reported by various groups. Accordingly, we will concentrate our attention on just one problem, but a problem that is of central importance in the analysis of coal structure; the determination of the aliphatic and aromatic CH content of coal and coal derived material.
