Abstract: China’s coal-to-olefin industry has been under rapid development in recent years. As of the end of 2018, the coal-to-olefin productivity (including methanol to olefin) totaled 1302×104t/a, occupying 21 percent of China’s total oflin productivity (ethylene + propylene). Currently, the coal-to-olefin project calls for high investment. It has a certain profit-making space when the crude oil prices are at high and medium levels, but the products are of serious homogeneity and low ends. The imbalance in distribution of coal and water resources is one of the main bottlenecks for coal-to-olefin development. The CO2 discharge from the production process is relatively high. The future development will face the issues of carbon taxes and cost. China sees a rapid growth in coal-to-olefin productivity, which is positively supplementary to petrochemical products to some extent. However, it also exerts more and more impact on the oil-to-olefin market. This competitive relations will be more obvious during the 14th Five-Year Plan period. The petrochemical enterprises should take advantage of the oil refining-chemical integration and petrochemical-chemical industrial chain to reduce the olefin production cost, accelerate transformation of oil refining to chemical industry, continue to optimize product structure, strength technological innovation, develop differential, high-end and high value-added products, continually enrich the current product structure and industrial chain, and further improve their own competitiveness.
