Spectrometry of Chars-Structure Studies

Studies of the very complex processes involved in pyrolytic reactions can provide insight into the mechanisms of natural geological processes such as coalification. Of primary interest in such studies is (1) the actual identification of the pyrolysis products, or, in lieu of this, information on the types of structures present, and (2) the effects of variables such as temperature and length of pyrolysis time on the structures of the products. Qualitative and quantitative comparisons of the pyrolysis products can then be made with similar natural products. In investigations of the structure and origin of coals, parallel studies of pyrolytic materials have provided considerable information about the coalification process.
