Rank Classification of Coal through Spectroscopic Methods
Coal characterization is a crucial step in the coal industry for determining its quality and suitability for various applications. Traditional methods like proximate analysis are time-consuming and destructive. Spectroscopic methods offer a efficient and non-destructive alternative for determining coal rank. These techniques utilize the absorption of electromagnetic radiation with coal samples to reveal characteristic spectral signatures associated with different rank levels. Common spectroscopic methods employed include Fourier Transform Infrared Spectroscopy (FTIR), which provide quantitative information about the chemical composition and structure of coal. By analyzing the spectral data, it is possible to associate specific absorption peaks or bands with different coal rank classifications, enabling accurate and objective rank determination.
