The nature and concentration of free radicals in natural and pyrolysed samples of several high-purity resinites, vitrinites and fusinites have been determined by electron spin resonance (e.s.r.) spectrometry. Careful measurements of theg-values, linewidths and integrated intensities have been made.
The results of conversion determinations on the products from Powhatan No.5 coal liquefied in an autoclave and in a high-pressure, high-temperature e.s.r. cavity are reported. Oil, asphaltene and preasphaltene yields, and overall conversion have been determined for Powhatan No.5 coal samples liquefi
In a continuing series of publications, a systematic investigation of the free radicals during coal depolymerization under SRC-II preheater/reactor conditions has been made. A uniquely designed electron spin resonance (e.s.r.) cavity allows the monitoring of free radicals and how they are affected b
## Samples of Belle Ayr (WY) subbituminous and Powhatan No. 5 mine (Pittsburgh Seam) bituminous coals were dried with gases including nitrogen, air and nitrogen/air mixture at temperatures essentially from ambient to 200ยฐC as part of a study to measure liquefaction behaviour. While the oxygen upta
