CROSS-LINKING REACTIONS OF OXYGEN GROUPS DURING LIQUEFACTION OF LIGNITE BY A NEW MODEL SYSTEM

摘要：

China has abundant coal resources, but low-to-medium rank coals account for 55％ of the total retained reserves. These low-to-medium rank coals have high moisture and oxygen content, a low energy density, be prone to weather and spontaneous combustion, and are also expensive in transportation. All these characteristics limit its high efficient utilization, but low rank coals usually have a relative larger porosity and high reactivity, so liquefaction can be realized under mild condition and the whole running cost can be reduced when these coals are used. Simultaneously, the domestic petroleum supply/demand gap and requirements for keeping the safety and stability of energy supply promote the development of coal liquefaction.
