In early June 2026, the Russian government announced an unprecedented export ban on jet fuel. Behind it lay a high-intensity campaign of Ukrainian drone strikes deep inside Russian territory — precise, "acupoint-style" hits in which the targets shifted from conspicuous storage tanks to the core units of secondary processing, such as catalytic cracking. These units were designed by Western companies, and under sanctions their spare parts are unobtainable; once damaged, the capacity they represent is lost for good. This is an energy-and-chemicals version of the "chip war": a shortcut you bought is a chokepoint someone else is aiming at.
The Truth About "Technology Lock-In" Laid Bare by a Precision Strike
Ukraine's drone tactics completed a crucial upgrade in this round of attacks. Earlier strikes on Russian refineries mostly targeted oil storage tanks — dramatic fires and short-term shutdowns could be touched off, but storage tanks are above-ground facilities that can be repaired quickly. The true heart of a refinery hides inside far less conspicuous equipment: catalytic cracking units, hydrocracking units, catalytic reforming units.
These secondary-processing units determine what share of its crude a refinery can convert into high-value products. Catalytic cracking units crack heavy gas oils into gasoline and liquefied petroleum gas; hydrocracking upgrades low-grade diesel into jet fuel; reforming yields high-octane gasoline blendstocks and aromatics. Without them, a refinery may sit on mountains of crude reserves and still fail to make enough road fuel and jet fuel.
The crux of the problem lies precisely in where these units came from. Most of Russia's core secondary-processing equipment was purchased from Western companies in the 1990s and early 2000s — UOP, Axens, Chevron Lummus Global — firms that hold the catalyst formulations, the reactor designs, and the parameters of the licensed process packages. Once the sanctions began, spare-parts supply was cut off, technical services were suspended, and catalysts could no longer be refreshed. When a drone warhead hits the internals of a catalytic cracking reactor, the question is no longer "which alternative supplier can we find" but "there are only a handful of companies in the entire world that can fix this."
Layer one — the process package: the catalyst formulation, the reaction temperature profile, and the regenerator air distribution of catalytic cracking are proprietary technology; no off-the-shelf alternative exists.
Layer two — the core equipment: the cyclone separators, distributor plates, and riser nozzles inside the reactor are custom-built by specific suppliers; replacing them means redesigning the entire unit.
Layer three — the catalyst: a catalyst's active components and matrix formulation are tightly coupled with the process package; swapping the catalyst amounts to swapping the whole process.
Russia's jet-fuel export ban is, in essence, not a proactive trade policy but a "self-declaration of a passive blockade" — once capacity falls off a cliff because the core units are damaged, mandatory export controls are nothing more than the predicament of "we simply cannot make any more" written into regulation.
A Forty-Year Path Walked Through: The Counter-Route of China's Energy-Chemical Industry
If Russia's experience is a lesson in "bought but unusable," then the path that China's energy-and-chemical industry has walked over forty years offers a precise counter-sample.
In the 1980s, the starting point of China's petrochemical technology was not much higher than Russia's at the time. The complete plants at large petrochemical bases such as Daqing Petrochemical, Qilu Petrochemical, and Yangzi Petrochemical were likewise imported from abroad — UOP's catalytic reforming, Lummus's ethylene, Snamprogetti's ammonia synthesis. But three differences in design led China, in the end, to an outcome entirely different from Russia's.
First: the internalized ecosystem of a super-sized central SOE. From the very beginning, Sinopec Group was never a mere "user." Under the same roof it holds engineering and construction companies (SEI, Luoyang Petrochemical Engineering, and others), catalyst plants, equipment manufacturers, and research institutes. At the same time that a plant was imported, the engineering companies were required to take part in the design from start to finish, dispatch engineers to learn on the job, and complete "reverse engineering" just as the unit came on stream. Localization of catalysts proceeded in parallel — from precious-metal hydrogenation catalysts to zeolite cracking catalysts, in-house development advanced almost in lockstep with plant imports.
Second: a "quasi whole-of-nation system" embedded in research institutes. China's petrochemical research strength was never broken up and scattered into enterprises or the market. Institutions such as RIPP (the Research Institute of Petroleum Processing in Beijing) and SRIPT (the Shanghai Research Institute of Petrochemical Technology) maintained their continuity through decades of institutional reshuffling. The family of catalytic-cracking catalysts developed in-house by RIPP not only meets all domestic demand but is exported in the reverse direction, to refineries in the Middle East and Southeast Asia. By the time sanctions became a reality, this R&D system had already been running for decades.
Third: domestic substitution across every link, from process packages to catalysts to key equipment. By the late 2000s, Sinopec was able to design and build million-tonne-class ethylene plants on its own. By the 2010s, in large refining-chemicals integrated projects, the localization rate of core equipment exceeded 95%. The key rotating equipment of catalytic cracking units — flue-gas expanders, axial compressors, main air-blower trains — is procured from domestic suppliers such as Shengu and Hangqi, no longer dependent on imports.
"When we imported the first 300,000-tonne ethylene plant in the 1980s, the foreign side wouldn't even let us touch the chairs in the control room — 'Do you even know how to use them?' they said. Later, when we set out to design our own ethylene plant, they said, 'There's no way you can pull it off.' Today, the refining-and-chemical technology contracts we export in a single year are worth billions of dollars. This is no miracle — it is forty years of accumulation that was never once interrupted."
Structural Comparison: The Bought Shortcut vs. the Walked Path
Russia's predicament and China's capability are not simply a binary of "sanctioned vs. unsanctioned." The divergence between the two countries' paths hides a deeper logic:
A bought shortcut cannot buy irreplaceability. Russia bought the plants but did not buy the knowledge reserves for "what if the plants are gone," the sustained building of talent pipelines, or the advance R&D of alternatives. When sanctions flipped the switch, it discovered that the end of the "shortcut" was not the possession of capability but a deep lock-in to its suppliers.
The walked path is not the straightest path. China's route was not always commercially optimal — developing a catalyst formulation in-house might take ten years, whereas buying the formula outright back then took only one. But the moat of the "slow answer" lies here: when external supply channels close, there is no need to reinvent the wheel — only to run the existing production lines at full tilt.
In energy and chemicals, sanctions transmit more lethally than in chips. In the semiconductor field, sanction pressure concentrates in the design and fabrication stages; sanctions delayed process-node upgrades, but legacy capacity could still be maintained. In refining and petrochemicals, a single-point failure in a core unit tugs directly at an entire national fuel supply chain. A catalytic cracking unit unable to produce qualified jet fuel may not be one refinery's problem — it may be the entire aviation industry's problem.
The Continuation of Industrial Logic: A Clustered Charge from Basic Energy to High-End Chemical Materials
China's energy-and-chemical industry has not stopped at "filling the basic-energy gap." In recent years, the industry's gaze has extended toward high-end chemical materials — ultra-high-molecular-weight polyethylene, carbon-fiber precursors, polyimide films, electronic-grade hydrofluoric acid. These materials were once dependent on imports for the long term, just like the catalytic cracking catalysts of an earlier era.
From the passive vulnerability of being choked at the neck to quietly laying down the bedrock of a great power's industry — this transformation was not accomplished by any single industrial policy, but by decades of sustained investment and systematic accumulation along the chain of "introduce → digest → innovate." The warning value of Russia's jet-fuel export ban lies precisely here: in critical fields, a bought shortcut is always only a shortcut; the path walked on one's own feet is the only real path.
The strikes on Russian refineries expose a deep structural predicament: a bought shortcut cannot buy irreplaceability. When a country relies on external technology supply in critical fields and has failed to build a complete capacity for autonomous substitution — spanning process packages, core equipment, and catalysts — then the moment external supply channels close, the vulnerability exposed across the entire industrial chain may be systemic. The moat accumulated over forty years of "introduce → digest → innovate" by China's petrochemical industry proved its worth at precisely the critical moment.
