I. Why Shaanxi's Fuel Processing Warrants Dedicated Study

Shaanxi is one of a handful of Chinese provinces that simultaneously supports large-scale crude oil production and coal-based chemical processing. The Ordos Basin beneath northern Shaanxi holds abundant oil, gas, and coal reserves. Yanchang Petroleum has operated in the region for over a century, while Yulin has developed a modern coal chemical system anchored by semi-coke (lántan), coal-to-olefins, and coal-to-methanol. These two parallel tracks define the basic structure of Shaanxi's fuel processing landscape.

In 2024, Shaanxi's above-scale industrial crude oil processing volume reached 19.83 million tonnes, up 5.9% year-on-year — an acceleration of 6.4 percentage points from the prior year, setting a historical record. (Source: Shaanxi Provincial Bureau of Statistics, 2024 Shaanxi Energy Industry Operations Analysis, March 2025) Behind this figure lies the accumulated output of multi-year technical upgrades at Yanchang Petroleum, PetroChina Changqing, and other major operators.

II. Oil Refining: Yanchang Petroleum's Century-Long Legacy and Modern Leap

Yanchang Petroleum Group is China's longest-operating onshore oil producer. In 2024, it produced 11.81 million tonnes of crude oil (ranked 7th nationally) and 10.46 billion cubic metres of natural gas (ranked 4th nationally), bringing total oil and gas equivalent to 20.15 million tonnes — entering the 20-million-tonne-level category for the first time.

On the downstream side, Yanchang has developed an integrated "coal-oil-gas resource utilisation" technology pathway, pursuing CCUS full-chain projects and direct synthesis gas-to-low-carbon-olefins conversion. In 2024, the Yulin Energy and Chemical Company (YECC) — a joint venture between Yanchang Petroleum and China Coal Energy — signed a licensing agreement with ECI Group to build a 150,000-tonne-per-year copolymer plant producing LDPE, EVA, and EBA products, marking a concrete step toward high-value-added chemical manufacturing in Shaanxi.

III. Coal Chemical Cluster: Yulin's Scale and Downstream Extension

Yulin is one of China's densest concentration points for coal chemicals. The city has completed 25 modern coal chemical projects, forming multiple integrated chains: coal–methanol–olefins, coal–oil products, coal–ethylene glycol, coal–ethanol, and coal–methanol–acetic acid. The Yulin High-Tech Zone alone hosts a cluster producing 4.8 million tonnes per year of basic chemicals with annual output value around RMB 40 billion.

Key installed projects within the zone include: Yanchang Yucoal Chemical (850,000 tpa methanol, 350,000 tpa acetic acid), China Coal Energy (600,000 tpa coal-to-olefins), and Lansi Petrochemical (800,000 tpa ethane-to-ethylene) — each representing investments of RMB 10 billion or more.

In 2024, the industry average all-in cost for coal-to-olefins was approximately RMB 7,319 per tonne, roughly RMB 1,054 per tonne cheaper than oil-derived olefins. This structural cost advantage sustains the competitiveness of Ordos Basin coal chemical hubs in Shaanxi, Inner Mongolia, and Ningxia.

IV. Shenmu Semi-Coke: The World's Largest Single-Product Cluster and Its Carbon Dilemma

Shenmu County is the world's largest semi-coke (lántan) production base. As of 2024, Shenmu had 56 enterprises with individual capacity of 600,000 tonnes or above, totalling approximately 39.8 million tonnes of installed capacity. Actual output in 2023 reached 24.8 million tonnes. (Source: China Price Information Network, Shenmu China Semi-Coke Industry Index 2024 Annual Report)

Semi-coke is prized for its low sulphur, low phosphorus, and high fixed-carbon content, making it essential for ferroalloy smelting, calcium carbide production, and clean residential heating — a product category unique to northern Shaanxi's coal processing landscape.

However, 2024 brought pronounced overcapacity pressure. Coal tar prices in Shaanxi fell to around RMB 3,233 per tonne in October 2024, down roughly RMB 674 from the same period a year earlier (Source: Mysteel), reflecting the sector's vulnerability to downstream ferroalloy and chemical demand cycles. In response, Shaanxi's provincial development and reform authorities promoted a technical upgrade model: replacing multiple small kilns with large-capacity 150,000-tpa units to achieve equipment-generation renewal without adding aggregate capacity.

V. Value Chain: Feedstock and Downstream Integration

Upstream inputs: Crude oil originates from Yanchang Petroleum's own production and PetroChina Changqing allocations. Coal feedstocks draw on the Shenfu Coalfield, where combined proven reserves in Shenmu and Fugu counties span hundreds of billions of tonnes, ensuring stable supply.

Downstream products: Refined petroleum outputs — gasoline, diesel, aviation fuel, LPG, and chemical intermediates — primarily serve industrial energy demand across Guanzhong and northern Shaanxi. Coal chemical derivatives are extending into polyolefins, vinyl acetate, BDO, and biodegradable materials such as polyglycolic acid (PGA), with the Guoneng PGA project representing the frontier of Shaanxi's coal-based degradable materials ambitions.

Equipment and auxiliaries: Large-scale hydrogenation reactors, heat exchangers, and gasifiers are mostly sourced from outside the province or overseas, reflecting a relative weakness in advanced equipment manufacturing within Shaanxi's energy chemical supply chain.

VI. Structural Challenges and Transition Pressures

Three constraints shape the sector's near-term trajectory:

Carbon management requirements: Yulin was designated one of China's first pilot cities for carbon peaking in November 2023, placing binding energy intensity and emissions targets on fuel processing facilities. Every major new project now passes through stringent energy review procedures.

Market cyclicality: The simultaneous softening of semi-coke prices and ferroalloy demand in 2024 demonstrated that large portions of the sector's output remain heavily exposed to upstream commodity cycles, with limited buffering from diversified product portfolios.

High-value product migration: The transition from methanol and basic olefins toward engineering plastics, high-performance fibres, and biodegradable materials requires fine chemical catalysts, specialty additives, and downstream formulation expertise — capabilities that remain in early-stage development within Shaanxi, making external technology partnerships a medium-term dependency.

VII. Industrial Geography and Procurement Perspective

Shaanxi's fuel processing capacity is concentrated in Yulin (coal chemicals, semi-coke), Yan'an (crude extraction and primary refining), and the Xi'an–Xianyang corridor (refinery and downstream chemical manufacturing). The pattern is "heavy north, lighter south," with Yulin as the supply-chain origin point and Guanzhong as the consumption and processing endpoint.

Sales teams supplying raw materials, consumables, equipment, or professional services to petroleum, coal, and fuel processing factories in Shaanxi can use Tianxia Gongchang to filter factory directories and contact details by region and industry category, enabling precise outreach to procurement decision-makers.
