This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of techniques of neutron-induced gamma spectrometry for non-invasive on-line instrumental analysis of coal for application to process streams in coal conversion plants is described. Using /sup 252/Cf sources and Ge(Li) detector based spectrometers, it appears feasible to monitor most of the elements in coal present in concentrations of 0.1 weight percent or more, including S, Fe, Si, Ca, Al, N, H, Ti, Cl, Na, K, and Mg. Correlations between gamma spectral response and element densities useful for quantitative analysis have been obtained for most of these elements. A substantially automated unattended laboratory prototype coal analyzer based on a /sup 252/Cf neutron source now continuously analyzes the gamma ray spectra from coal contained inside pipe-simulating cylindrical metal containers and prints out composition information on command. 15 figures.
