In industrial gas separation and purification processes, PSA (Pressure Swing Adsorption) systems are widely used in hydrogen production, oxygen production, nitrogen production, and gas drying. However, many users encounter a common problem in actual operation: decreased system efficiency, unstable gas purity, and continuously increasing energy consumption. Many people’s first reaction is to blame the equipment, […]
I. Why are membrane coating materials needed? In lithium-ion batteries, the membrane’s function is to isolate the positive and negative electrodes while allowing lithium ions to pass through. However, traditional polyolefin membranes (PE/PP) have significant problems: · Poor high-temperature resistance (shrinkage begins around 130℃) → prone to thermal runaway · Poor wettability → weak electrolyte […]
In natural gas purification processes, COS (carbonyl sulfide), a common organic sulfide, is widely present in natural gas, LNG, and refining gases. Due to its stable chemical properties and difficulty in direct removal, COS not only affects the performance of downstream catalysts but also corrodes equipment and can even lead to excessive sulfur content in […]
In the field of industrial gas processing, the presence of moisture not only compromises product quality but can also lead to equipment corrosion, catalyst deactivation, and increased system energy consumption. Consequently, selecting an efficient and stable drying medium is of paramount importance. Activated alumina desiccant, distinguished by its exceptional adsorption properties and regenerative capabilities, stands […]
I. How Does Activated Alumina Desiccant Impact Energy Consumption? Activated alumina is a porous material characterized by a high specific surface area and strong adsorption capabilities, enabling it to efficiently remove moisture from gases. 1. Enhancing Drying Efficiency and Reducing Energy Loss High-quality activated alumina desiccants possess a greater adsorption capacity and a faster adsorption […]
In the fields of industrial waste gas treatment and air purification, H₂S (hydrogen sulfide) and VOCs (volatile organic compounds) rank among the most common and challenging pollutants to treat. While traditional adsorption materials often suffer from issues such as low removal efficiency and short service life, potassium permanganate-impregnated activated alumina has emerged as a core […]
In the modern petrochemical, refining, and environmental protection industries, the performance of a catalyst depends not only on its active components but is also closely linked to the catalyst support material employed. Selecting an appropriate support can significantly enhance catalytic efficiency, extend service life, and reduce operating costs. Among the multitude of available materials, activated […]
I. Core Functions of Inert Support Spheres Inert support spheres are mainly used at the bottom of fixed-bed reactors or below the catalyst bed. Their core functions include: · Supporting the catalyst bed: preventing catalyst particles from collapsing or leaking. · Optimizing gas and liquid distribution: improving the uniformity of the reaction medium. · Protecting […]
In modern industrial production, gas purification is crucial for ensuring product quality, extending equipment lifespan, and meeting environmental protection requirements.
