According to the disclosure of China Coal Group, China National Coal Energy Corporation and Hulunbeier Municipal Government recently signed an agreement for the construction of a 2×10 million tons brown coal comprehensive utilization project. The total investment of the project is approximately 18 billion yuan, and low-rank coal conversion technology (LCC) is proposed. The liquid fuel obtained by lignite upgrading processing is low-temperature coal tar, and naphtha, diesel and other oil products can be obtained through processing and refinement. The solid fuel available for lignite upgrading and processing is semi-coke (PMC), the calorific value is nearly doubled, and the sulfur content is greatly reduced. It is a high-quality and environmentally friendly solid fuel, and can be used as a gasification raw material for coal gasification in chemical plants. Can also be used for blast furnace injection, ferroalloy and other industries used as reducing agent admixture.
