Economic Viability Underpins Strategic Shift

The economics of coal-based olefins production remain compelling at current commodity prices. Industry analysis indicates production costs around 6,300 yuan (US$900) per tonne—approximately 1,500 yuan below oil-based routes—with breakeven occurring at prices as low as US$35 per barrel of oil, while other sources cite CTO cost advantage when coal prices are below ¥1,000/tonne and oil prices exceed $60/barrel. This cost advantage provides substantial margin protection even in lower oil price environments, reinforcing the technology's commercial sustainability beyond purely strategic considerations.

Energy Security Drives Feedstock Diversification

The expanded CTO deployment aligns with China's broader energy security objectives, leveraging domestic coal reserves to reduce dependency on imported crude oil for petrochemical feedstocks . Olefins—primarily ethylene and propylene—serve as fundamental building blocks for plastics, synthetic fibers, and elastomers, making feedstock flexibility strategically critical for downstream chemical manufacturing .

ppPLUS Technology Modeling Initiative: Our team is currently developing comprehensive technology models and capacity assessments of China's coal-to-chemical industry, incorporating process configurations, mass balance calculations, and competitive positioning analysis across the CTO, methanol-to-olefins (MTO), and integrated gasification platforms.
