Scientists of the university built a low-temperature carbonization process at the Myonggan Chemical Factory and opened a prospect for producing the raw materials of chemical products.

And they dynamically pushed ahead with the research for providing the sci-tech guarantee for the production of the raw materials by the mixed solvent extract method instead of the previous method of using alkali.

The cost-effective research results which can prevent the environmental pollution have been introduced into field.

They now look to ways of using lignite in metallurgical industrial sector with a sci-tech guarantee.
