I. Common Types of Gas Purification Adsorbents 1. Activated Alumina Key Characteristics: · Strong water absorption capacity; suitable for gas drying · Possesses a certain adsorption capacity for acidic gases such as H₂S, HF, and SO₂ · High mechanical strength, water-resistant, and highly regenerable Typical Applications: Compressed air drying, pretreatment for PSA systems, acidic gas […]

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 […]
