Advances in Rotary Kiln Processing of Zinc-Bearing Steel Dust and Sludge
2026-03-31
The treatment of zinc-containing dust and sludge from steel plants in rotary kilns is a mainstream pyrometallurgical resource recovery technology. The core of this technology is the high-temperature reduction and volatilization of zinc, the recovery of secondary zinc oxide, and the return of iron slag to production. In recent years, the main progress has been made in balling pretreatment, multi-field precise control, circle formation inhibition, deep utilization of waste heat and flue gas, and high-value product development, achieving efficient zinc removal, energy conservation, carbon reduction, and the co-processing of multiple solid wastes.
Raw Material Substitution: High-Quality Petrochemical Development
2025-12-22
At present, China’s petrochemical industry is facing the dual challenges of global overcapacity and high domestic raw material costs. In particular, the shortage of low-cost feedstocks such as associated gas from oilfields and shale gas in China has led to persistently high production costs of core chemical products like ethylene. In 2023, a stark contrast emerged where U.S. counterparts reaped substantial profits while Chinese enterprises suffered across-the-board losses. How to break this dilemma? The article Raw Material Substitution Boosts High-Quality Development of China’s Petrochemical Industry published in the journal Chemical Industry and Engineering Progress points out a clear direction. Combining the core viewpoints of the original paper, this article helps readers understand the core logic and practical approaches of raw material substitution.
"A Comprehensive Comparison of Oil Sludge Treatment Techniques"
2025-12-05
At present, there are nearly ten treatment methods for oily sludge, such as solvent extraction, solidification treatment, biological treatment, profile control treatment, drying and incineration, chemical hot washing, pyrolysis treatment, etc. In terms of treatment methods, these can be divided into physical and chemical methods and biological methods. Research hotspots mainly focus on solvent extraction, biological treatment, solidification treatment, incineration treatment and pyrolysis treatment, etc. The table below provides a comparison of various treatment methods in terms of economy and environmental protection.
China's Cellulosic Ethanol Development Path Becomes Clearer
2025-11-04
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.
