“煤”想到，它也能变油？！

Core Viewpoint - The article emphasizes the potential of coal as a valuable resource for oil production in China, leveraging advanced technologies to convert coal into liquid fuels, thereby enhancing energy security and diversification [3][14]. Group 1: Coal to Oil Technologies - Two core technologies for coal-to-oil conversion have received national-level recognition, showcasing China's strong capabilities in this field [5]. - Direct liquefaction of coal involves high temperature and pressure processes with catalysts to convert solid coal into liquid products like naphtha, kerosene, and diesel [6][7]. - Indirect liquefaction of coal utilizes oxygen for incomplete combustion, producing synthesis gas (CO and H2), which is then converted into liquid hydrocarbons through Fischer-Tropsch synthesis [9]. Group 2: Practical Applications and Projects - The direct liquefaction technology has been implemented in a demonstration project by the National Energy Group, producing clean oil products with a designed capacity of 1.08 million tons per year [17]. - The indirect liquefaction technology is applied in the world's largest single-unit project with a capacity of 4.05 million tons per year, also operated by the National Energy Group, producing various oil products including diesel and liquefied natural gas [20].
