摘要:
This paper provides an overview of the nature, behavior and significance of free radicals in coals, coal components and fractions during coal conversion processes. Special emphasis is placed on the characterization of free radicals and their dependence on pyrolyis and liquefaction process conditions. Some preliminary results are provided from the recently developed technique for the in situ observations of free radicals under preheater/reactor conditions.
