Book excerpt: Development of techniques of neutron-induced gamma spectrometry for non-invasive 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, and K. Correlations between gamma spectral response and element densities useful for quantitative analysis have been obtained for most of these elements. A substantially automated 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 cans and prints out composition information on command. Our recent work with fast neutrons from a neutron generator suggests that this source may be preferable for determination of carbon and oxygen in the coal.
