Abstract

Abstract

In order to alleviate the risk caused by China's high dependence on oil import, the development of a coal-to-liquid process that converts coal into oil through scientific means is a practical mean. This article reviewed the four most common coal-to-liquid technologies in China, analyzed the advantages and disadvantages of the four coal-to-liquid technologies, and provided a basis for the research of coal-to-liquid technology. The coal-to-liquid residue was the main pollution product of the coal-to-liquid industry. This article also classified the residues produced by different coal-to-liquid processes, summarized their composition and physical and chemical properties, and selected the direct coal liquefaction residue system to explain the current utilization technology of coal direct liquefaction residues. The research progress mainly included four parts:combustion, pyrolysis, preparation of asphalt products and the other. It was suggested that the development trend of coal-to-liquid technology was to study the structure conversion process of coal, cheaper and more efficient catalysts and their catalytic principles, high-throughput reactors for catalyst separation, and product separation technology. Among the high-value utilization methods of coal-to-liquid residue, asphalt products and high-performance carbon materials had good economic prospects and research value.
