Molecular Structure of Needle Coke Carbon Framework: Raman Spectral Data

Raman spectroscopy is used to investigate samples of needle coke. Numerical Raman characteristics are obtained: the graphitization degree and the disorder of the carbon framework. By analysis of the Raman spectra of the coke samples, the graphitization of the molecular fragments within the coke’s carbon framework may be investigated; the completeness of coking may be assessed; and the final coke quality may be estimated.
