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.
Dolly is mainly used for the connection of front and rear trailers of double trailers or road trains. As a key connection conversion device, semi-trailer trailers are used to promote the The simple single-hanging mode has played a huge role in the development of the double-hanging or even multi-hanging mode, which has greatly improved the efficiency of logistics transportation.
