Abstract

It is well recognized that coal pyrolysis follows free radical mechanism. Most literature however studied mainly the free radicals in solid products. Free radical information about coal tar is very important not only for in-depth understanding on pyrolysis mechanism but also on optimization of the processes for high oil yield and stable operation. This paper reports our recent study on free radical concentration of coal tars generated from 4 coals under various pyrolysis conditions or subjected to various downstream conditions.
