Abstract: The development of energy and related chemical technologies is closely related to the development of the national economy and national security.In the process of rapid development in China, some technologies with independent intellectual property rights developed in the field of energy and chemical industry have reached the international leading level. Promoting the export of energy and chemical technology plays an important role in promoting economic development, improving the technical content of my country’s export products, optimizing the structure of export products, developing and protecting foreign commodity markets, and driving the export of products and equipment. Studying the potential export capacity of coal chemical technology is a necessary work to promote technological output. At present, China has not yet formed a complete set of indicators for evaluating the potential export capacity of technologies in the coal chemical industry. In this regard, an evaluation index system for the potential export capacity of coal chemical technology was constructed, and a quantitative evaluation method for the potential export capacity of coal chemical technology was proposed using the AHP. On the basis of the existing research results, this method was used to evaluate the representative complete sets of technologies: coal gasification technology - Shenning furnace, methanol to olefin technology - DMTO and coal indirect liquefaction technology package (Zhongke Synthetic Oil). The evaluation result is that coal gasification technology-Shenning furnace ranks first, followed by methanol to olefin technology-DMTO and indirect coal liquefaction complete process technology package (Synfuels China). At the same time, it is found that the key factors restricting the export potential of China’s coal chemical technology are overseas competitiveness, international recognition and technical performance. In this regard, the following suggestions are put forward:① Improve the export policy of energy and chemical technology, strengthen policy support, and create a favorable environment; seize the opportunity, promote transformation and upgrading, and achieve sustainable development; ② Strengthen independent research and development, improve the level of process technology, and establish a International brand image.
