Abstract:The clean and efficient use of coal is of great significance to China's energy security and environmental protection. Coal to liquids, coal to olefins and coal to glycol are the major clean coal technologies of Chinese Academy of Sciences (CAS), which have reached the international advanced level and become the innovation models in China's energy development. To cross the gap between the laboratory and industrialization, different approaches are used to integrate social resources in transformation of scientific and technological achievements. This paper reviews the industrialization development and various situations encountered in technology transfer and transformation of these three technologies. From the existing problems and challenges, the suggestions are proposed for the next step of the technology transfer and transformation.
