I. Why It Matters

Sichuan is widely known as a major natural gas province, yet its full fuel processing landscape extends well beyond that label. This landlocked southwestern province enjoys three rarely co-existing raw material pillars: Southwest China's largest integrated refinery sits in Pengzhou, north of Chengdu; Panxi region's coking coal underpins what is arguably the largest coking production base in western China; and decades of natural gas chemical development in southern and northeast Sichuan have produced a cohort of synthetic ammonia and methanol producers.

These three strands operate independently yet together constitute an industrial cluster with annual output value running into the hundreds of billions of yuan. With domestic refining capacity under structural pressure, the coking sector facing tightening carbon constraints, and natural gas chemicals extending toward specialty products, Sichuan's cluster sits at a telling inflection point.

II. Pengzhou Refining: Southwest China's Scale Ceiling

PetroChina Sichuan Petrochemical Co., Ltd. (commonly "Sichuan Petrochemical" or "Pengzhou Petrochemical"), located in Pengzhou City, Chengdu, is Southwest China's first large-scale integrated refining and chemical project and currently the region's largest refinery. The core facility comprises a ten-million-tonne-per-year crude refining unit paired with an 800,000-tonne ethylene cracker, which entered operation in 2014.

In terms of output, Sichuan Petrochemical delivers approximately five million tonnes of refined products and three million tonnes of basic chemical feedstocks annually (Source: PetroChina News Centre, October 2024). Aviation kerosene alone covers about 80% of demand across 16 Sichuan airports, while over 3.5 million tonnes of automotive fuel supply the Chengdu-Chongqing region each year.

On the economic side, Sichuan Petrochemical accounted for nearly one-sixth of Pengzhou City's 2023 GDP, making it the locality's single largest industrial enterprise. In 2024 the company was recognised as one of only five integrated refining and chemical enterprises nationally to achieve "advanced green development" status, and it commissioned a fuel-cell hydrogen production unit.

Looking ahead, Sichuan Petrochemical's strategic priority is not capacity expansion but "reducing oil, increasing chemicals"—raising the share of chemical feedstock output to navigate China's broader refining overcapacity.

III. Panzhihua Coking: Western China's Coal Chemistry Hub

Panzhihua, at the Sichuan-Yunnan border, hosts the most concentrated coking capacity in western China, built on the primary coking coal of the Panxi coalfield. The anchor enterprise, Panzhihua Panjiang Coal Coking Co., Ltd., operates six coke ovens within the Pangang Luoluoping plant complex, with annual capacity of 3.45 million tonnes of coke, 150,000 tonnes of coal tar, 36,000 tonnes of crude benzene, and coal gas processing capacity of 220,000 cubic metres per hour (Source: Pangang Group official website).

Coal supply is handled by Sichuan Coal Group's Panmei branch, whose Dabaoding, Huashan and Taiping mines form a vertically integrated chain from raw coal through washing to coking (Source: Sichuan State-owned Assets Supervision and Administration Commission, April 2025).

Panzhihua is repositioning coking as a priority target for green and low-carbon transformation. Panjiang Coal Coking has commenced ultra-low emission retrofits; in Panzhihua's West District the fossil energy share fell from 74% to 67% in 2024, with carbon emission intensity down 24.8% (Source: Contemporary County Economy, Issue 10, 2024). Panzhihua has also been designated a hydrogen industry demonstration city, with utilisation of by-product hydrogen from coking emerging as a viable transition pathway.

IV. Southern Sichuan Natural Gas Chemicals: Historical Depth and Specialty Extension

The Luzhou-Yibin corridor in southern Sichuan is the cradle of Sichuan's natural gas chemical industry. Luzhou Lutianhua (originally the Luzhou Natural Gas Chemical Plant, established 1959) long centred its output on synthetic ammonia and urea, with annual urea capacity around 1.47 million tonnes, synthetic ammonia output at the million-tonne scale, and methanol capacity approximately 700,000 tonnes (Source: Lutianhua Co., Ltd. official website).

At the provincial level, Sichuan's green chemical industry recorded operating revenue of 650 billion yuan in 2023, and in 2024 the chemical raw materials and products sector grew 18.8% year-on-year (Sources: Sichuan Government website, June 2024; Sichuan Bureau of Statistics, January 2025). These figures partly reflect the pull effect of natural gas chemicals extending into downstream specialty products.

Leshan's green chemical industry posted output of around 28 billion yuan in 2024, with a target exceeding 100 billion yuan by 2029; synergies between its phosphorus and silicon value chains and natural gas chemicals are beginning to materialise (Source: Sichuan Government website, March 2025).

V. Challenges and Structural Tensions

Sichuan's fuel processing industry faces three structural pressures:

Refining: Domestic refining capacity is in cyclical oversupply, and transport fuel demand growth is softening. The pace at which Pengzhou Petrochemical executes its "reduce oil, increase chemicals" pivot will be the key determinant of its medium-term competitiveness.

Coking: Expectations of peak domestic crude steel output are feeding into coking demand, compounded by tightening carbon-market obligations. Ultra-low emission retrofits carry substantial capital requirements, and portions of the capacity face medium-term compliance risk.

Natural gas chemicals: Reform of upstream gas pricing has proceeded slowly, and some natural gas chemical units are under economic pressure; the transition toward differentiated, higher-value products remains in its early stages.

The three poles currently lack organic integration—by-product streams from Pengzhou refining, coke oven gas from Panzhihua, and synthesis gas from southern Sichuan have not yet formed mature cross-regional utilisation pathways. This gap is both a current weakness and a latent consolidation opportunity.

VI. Supply Chain Perspective

Suppliers serving Sichuan's fuel processing enterprises can use Tianxia Gongchang to screen factory directories and procurement decision-maker contacts by Sichuan Province and fuel processing industry, targeting buyers in refining, coking, and natural gas chemicals sub-segments.

Core procurement categories for these enterprises include industrial catalysts (hydrogenation, reforming), specialty refractory materials, coke oven mechanical equipment, large-scale storage tanks and piping systems, and environmental control equipment (desulphurisation, denitrification, VOC recovery). These categories are served by specialised industrial distributors and equipment manufacturers rather than general commodity channels.
