Coal Analysis by Nuclear Methods

The International Journal of Applied Radiation and Isotopes, 1983
The paper reviews the use of low-energy x-rays, γ-rays and neutron interaction techniques for coal analysis in applications which range from borehole logging to on-line analysis in coal preparation plants and in coal-burning power stations. Neutron-induced prompt γ-ray analysis provides an exciting prospect for the future as it allows direct on-line ...

Coal analysis using thermogravimetry

Thermochimica Acta, 1984
Thermogravimetric analysis is being used increasingly today to obtain kinetic data related to coal decomposition. However, this method is open to criticism on the basis that the meaning of the activation energy of solid state reactions obtained from TG experiments is not clear.
