Abstract:

Coal to olefins is the most profitable modern coal chemical process in recent years, and its development trend has aroused widespread concern in the petrochemical industry. In this paper the development status of coal-to-olefins technology, especially methanol-to-olefins technology, was introduced, and the development trend of coal-to-olefins technology was discussed. It was concluded that coal-to-olefins technology was generally mature and had been applied in large-scale industrial production in China, but it still needed to be further improved, especially to speed up the technological innovation, so as to possess our own intellectual property rights in coal-to-olefin integrated whole-process technology as soon as possible. With the rapid growth of coal-to-olefin capacity in China, the competition between petroleum olefins and coal-to-olefins will be more intense in the future. Therefore, based on the reality of the industry, full play should be given to the advantages of petrochemical and coal chemical industries, and to speed up technological innovation and product structure adjustment. Efforts should be made to realize the differentiation and high-end structure of olefin products, to promote the complementary advantages of petrochemical and coal chemical industries, and to jointly promote the production of chemical products in China towards the goal of high-quality development.
