摘要：

Infrared emission spectroscopy has been used to monitor the chemical modifications taking place in the organic and inorganic components during the pyrolysis of Kerosene Creek shale and the products of its demineralization. The samples were heated in the range 50-700-degrees-C in the presence of argon. The results show the progressive decrease of the signals due to CH2 and CH3 vibrations, as well as the carbonyl and carboxylic peaks, and their subsequent disappearance at higher temperatures. Also evident is the appearance of a signal due to aromatic protons at -450-degrees-C for some samples. The effectiveness of the demineralization procedure can be assessed by comparing the spectra of the raw and demineralized shale. These results have been compared with room temperature transmission spectra of the same samples.
