As of March 23, 2026, tensions in the Strait of Hormuz have intensified amid a US-Iran standoff. A 48-hour ultimatum previously issued by the United States is set to expire at 7:45 Beijing Time on March 24. In response, Iran has imposed targeted shipping restrictions, banning vessels from hostile nations while allowing negotiable passage for ships from non-hostile countries. Disruptions to this global "chokepoint" for energy and trade are rapidly rippling through the global trading system, delivering an all-round, systemic shock to global foreign trade across energy supplies, shipping logistics, and supply chain security.

At present, China's petrochemical industry is confronted with the dual challenges of global overcapacity and high domestic raw material costs. Particularly, China lacks low-cost raw materials such as associated gas from oil fields and shale gas, which leads to persistently high production costs for core chemical products like ethylene. In 2023, there was a situation where related products in the United States were highly profitable while Chinese enterprises suffered comprehensive losses. How to break this deadlock? The article "Raw Material Substitution Facilitates High-Quality Development of China's Petrochemical Industry" published in the journal "Chemical Industry and Engineering Progress" has pointed out a clear path for us. This article, based on the core viewpoints of the original text, will help you understand the core logic and practical directions of raw material substitution.

Introduction:With the deepening of the "Dual Carbon" strategy, cellulosic ethanol, as a core direction of second-generation bio-liquid fuels, has regained focus in the energy and chemical industry due to its significant potential in emissions reduction, avoiding competition with food supplies, and waste resource utilization. Through over a decade of technological accumulation and engineering demonstration, China has achieved a series of breakthroughs in core technologies, equipment, and industrial demonstration, moving from the "technology verification" stage to the critical "pre-commercialization" phase.
