China Expands Coal-to-Chemicals as Oil Import Shock Reshapes Feedstocks
China is relying more heavily on coal-derived fuels and petrochemical feedstocks as reduced crude imports and supply disruption from the Middle East reshape its energy and chemical system.
The shift predates the Iran war, but the disruption has increased the strategic value of domestic feedstock alternatives.
China already uses coal to produce oil, gasoline, naphtha and other chemical products, while investment in coal-to-chemical projects continues to expand in resource-rich inland provinces.
Coal-derived products already represent substantial volume
In 2024, China's output of refined products made from coal was equivalent to processing nearly 300 million barrels of crude, according to data cited by The Wall Street Journal.
That is roughly equal to one month of Chinese crude imports in that year.
The country's coal-to-chemical sector includes oil, gas, olefins and ethylene glycol, linking energy security directly to petrochemical feedstock availability.
Xinjiang output is expanding quickly
Low coal prices have supported a new wave of investment in northwestern China.
In Xinjiang, production of naphtha and diesel from coal nearly doubled in 2025 from the previous year.
That gives refiners and chemical producers another domestic source of molecules that would otherwise need to come from crude-oil processing or imported feedstocks.
The economics remain sensitive to coal prices, plant efficiency and environmental policy, but the physical supply contribution is becoming harder to ignore.
Refiners are adjusting to weaker fuel demand
China's rapid adoption of electric vehicles has reduced domestic demand for conventional road fuels.
Refiners have responded partly through exports of gasoline, diesel and jet fuel and through greater emphasis on petrochemical output.
China is also a major exporter of petrochemical feedstocks such as ethylene, which are used in plastics, packaging and other manufactured goods.
That makes refinery utilization and product-export policy relevant not only to fuel markets but also to chemical supply chains.
Feedstock diversification is becoming strategic
The current oil-import shock shows why China values multiple feedstock routes.
Coal-based production cannot replace the conventional refining system, but it can reduce dependence on imported crude at the margin and provide more flexibility when maritime supply is disrupted.
For petrochemical buyers and producers, the key variables now include:
- crude-import availability;
- coal-to-chemical operating rates;
- naphtha supply;
- olefin and ethylene glycol output;
- refinery utilization;
- export policy.
The broader trend is clear: China's petrochemical feedstock system is becoming more diversified as energy security and trade disruption shape investment decisions.
