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.

As the "green hydrogen-to-ammonia (H2A) - green ammonia-to-hydrogen (A2H)" cycle model proposed in the paper "Research Progress and Prospects of Hydrogen-Ammonia Green Cycle" published in the journal "Chemical Industry Progress" continues to be implemented, China's hydrogen-ammonia green energy industry is experiencing explosive growth. Recently, a series of major developments have emerged one after another: Goldwind Science & Technology plans to invest approximately 18.92 billion yuan in a wind power-to-hydrogen, ammonia and methanol project, the first phase of Envision's Chifeng 1.52 million-ton green ammonia project has been put into production, and Jidian Co., Ltd.'s Da'an green ammonia project has set four global records. These milestones mark that this emerging track, which can solve the problem of hydrogen storage and transportation and promote the decarbonization of traditional industries, has moved from the laboratory to large-scale commercial operation.

The efficient and environmentally sound treatment of oily sludge is a critical challenge for the petroleum industry's green transformation. This article systematically reviews the principles and characteristics of mainstream treatment methods, from traditional landfilling and incineration to modern biological and pyrolysis technologies, aiming to provide a clear reference for technology selection within the industry.

In 2025, with the deepened "dual carbon" policy and upgraded environmental standards, resource utilization of industrial solid waste and harmless treatment of high-viscosity materials have become industry focuses. Per the 2024 White Paper on the Renewable Resources Industry, 32% of SMEs see over 15% raw material loss due to poor sorting accuracy of solid waste equipment, driving urgent demand for high-efficiency, eco-friendly equipment². Against this backdrop, Luoyang Kaizheng Environmental Protection Technology & Equipment Co., Ltd. (hereinafter "Luoyang Kaizheng") offers customized industrial clean production solutions via its three core business segments.

In the great journey of striving towards carbon peak in the industrial field, environmental protection process equipment such as ball rollers, mixers, compaction granulators, cold and hot pressing technologies have become the core driving force for promoting green transformation in key industries. This series of actions not only demonstrates the power of technological innovation, but also embodies a profound commitment to efficient resource utilization and environmental protection.

It has been found through practice that the finished ore produced by the grate machine rotary kiln process has the characteristics of uniform quality, good metallurgical properties, more usable fuels, and strong adaptability to raw materials. This article introduces what equipment should be equipped with this production line equipment.

Our company has been recognized as a "SRDI Enterprise". We have been focusing on the development of integrated solutions for raw material preparation, batching, solid waste, residual material and recycled material processing. Our goal is to help clients process all kinds of materials more effectively and produce value from them.

In the past 20 years, many sintering plants have continued to innovate traditional sinter material preparation technology. Japanese companies such as Sumitomo and Nippon Steel were the first to use vertical intensive mixers for mixing sinter materials. Through research and practice at Sumitomo Wakayama Third Sintering Plant, the use of a vertical powerful mixer instead of a cylindrical mixer has enhanced the mixing effect of the sintered raw materials, and the corresponding granulation effect has also been enhanced, ultimately making the sintered raw materials highly breathable. The sintering speed is increased by 10%~12%, and the coke powder addition ratio can be reduced by 0.5%.
