✦ Synopsis

Nine Canadian coals of different rank and composition were studied by electron spin resonance. For percentage of fixed carbon in the range of 43 to 78 wt%, the free radical g values were found to increase with decreasing carbon content, and did not level off for the low rank coals. The free radical linewidths are attributed to atomic species such as oxygen and not to protons of hydrogen.

Studies of the dependence of electron spin resonance on heat treatment temperature were carried out for coal carbons made from coals of various rank. The absorption curve of coal carbons changes from Gaussian type to Lorentzian type, the line width decreases and reaches a minimum, and the spin cente

Three Western Canadian coals were gasified with air and steam in a fluidized bed of 0.73 mm sand and coal, at atmospheric pressure and temperatures of 1023-l 175K to produce a low-calorific-value gas. One non-caking and two caking coals were tested. The effects of temperature, coal feed rate, air/co
