摘要
The present invention comprises a process of organo-refining of coal to produce low ash (4%) clean coal with higher yields of 65%-70%. Dried coal sample was extracted under reflux conditions with a solvent containing N-methyl 2- pyrrolidone (NMP) and ethylenediamine in a ratio of coal NMP:EDA of 1:17:1. The process of organo-refining of coal to obtain clean coal with low ash (4%) within permissible limit for coke making in high enough yield for coke making has been described.
