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.

High viscosity self-cleaning mixing equipment is mainly used in the field of adhesive substances, cosmetic products, lubricants, pigments, resins, rubber and plastic auxiliary substances, emulsions, industrial dyes and other chemical products, in these areas it has played its strengths with its unique features, so that the prospects are very good. High viscosity mixer is a collection of dispersion, stirring and mixing as one of the multifunctional and efficient equipment, more and more enterprises, researchers love. So specifically how is the high viscosity mixer used in the paint industry?

BB fertilizer is usually called blended fertilizer, which is a kind of compound fertilizer with at least two nutrients of nitrogen, phosphorus and potassium in specified amounts made by dry mixing method. In the process of BB fertilizer production, the mixing process is the key link to determine the product quality and production efficiency. As the leading equipment in the mixing process, the performance of the mixer will directly affect the product quality and production efficiency. This article briefly introduces the 12 tons per hour BB fertilizer mixing equipment.

Mixing equipment is widely used in food engineering, chemical engineering, biological engineering and other industries. They have an important impact on the process effect and product quality. Along with the gradually perfect and mature production technology, the technological parameters of mixing equipment, structure and stability, especially in the process operating conditions under the condition of same capacity only different, this kind of device is often just the difference of shape size, volume, power, size, number of assembly structure of the equipment, spare parts and types are basically the same. This provides necessary conditions for the standardization, standardization and modular design of mixing equipment. This paper briefly introduces the development of 3d parametric CAD system for mixing equipment.

Mixing of highly viscous fluids is a common unit operation in industry, and many industrial sectors encounter mixing or kneading operations of highly viscous fluids, such as rubber, petroleum, plastics, coatings, inks, and synthetic fibers, cosmetics, pharmaceuticals, food, paper and cement industries.

Powder mixing is a common operation in industrial production, which is widely used in the chemical industry, pharmacy, food, and construction. It is one of the most critical operation procedures in the production of medicines, feed, cement, and other products. Powder material mixing refers to the operation process in which a variety of powder particles with different components change their moving speed or direction in the mixer, and finally, make the particles with different components randomly and evenly distributed in the mixer.

Solid preparations of solid beverages, health food and drugs all need to mix the components of solid powder. The proportion of components in the formula can reach 80%-90%, and the proportion of components is less than 1%. The forms are powdery, granular and flaky.
