What is Coal refining system?
The coal refining system refers to a comprehensive technical system that purifies and transforms raw coal through a series of physical and chemical processes to enhance its energy value and environmental compatibility. This system involves multiple steps, including but not limited to crushing, screening, washing, desulfurization, deashing, and more advanced coal gasification and liquefaction technologies. Among them, desulfurization is a key link aimed at reducing sulfur dioxide produced during combustion, thereby reducing air pollution. Coal gasification converts coal into synthesis gas through high temperature and catalyst action, while coal liquefaction converts it into liquid fuels such as diesel and gasoline through a hydrogenation process. These advanced refining technologies not only improve the economy and combustion efficiency of coal, but also reduce the impact on the environment. They are one of the key technologies to promote energy transformation and sustainable development.
