- 1 - Abstract: A method of upgrading low-rank coal comprises the steps of dehydrating crushed low-rank coal using a rotary drum in a drying section, dry distilling the coal dehydrated in the drying section in a rotary drum in a dry distillation section and subsequently cooling the dry- distilled coal in a cooling section, while enabling the coal to adsorb tar produced from the coal in the dry- distillation section. The present invention makes it possible to continuously upgrade large quantities of low- rank coal with a high moisture content and hence a low calorific value, to provide upgraded coal with an increased calorific value and which is not prone to spontaneous combustion.
