Study of pretreatment on Baiyinhua lignite in thermal extraction process
In order to solve the problem of low thermal extraction rate of lignite, the raw coal is pretreated with acid and alkali as solvent, and then the pretreated raw coal is subjected to thermal extraction reaction to prepare ultra-pure coal under the process conditions of operating temperature 380 ℃, no...
