Study on applicability of clean utilization technology of lignite in Xilingol
The recoverable reserves of lignite in Xilingol are more than 140 billion tons,and the annual production is more than 100 million tons.It is mainly used for power generation and heating through combustion,with low efficiencyand low quality,thus the efficiency and cleanness of lignite utilization in Xilingol needs to be improved.Taking Gray-King assay,pyrolysis and direct liquefaction technology as research methods,the transformation of representative lignite in Xilingol were studied.It was found that three kinds of coal samples showed different characteristics in different directions of clean utilization technology,XM-1 was more suitable for making semi-coke,XM-2 was more suitable for gasification technology,and XM-3 was an excellent coal for direct liquefaction.Based on the experimental results,combined with the characteristics of resources and environment in Xilingol,it is considered that low-temperature distillation is the suitable technology for clean utilization of Xilingol lignite in the future.
