Spherical particles have a relatively regular shape and, with relatively uniform particle sizes, are more likely to form a stable adsorbent bed. For potassium permanganate activated alumina, this is particularly important because its actual performance depends not only on the chemical properties of the material itself, but is also closely related to the residence time of the gas in the bed and the gas-solid contact conditions. Proper spherical particles can achieve a better balance between adsorption performance and gas flow, making potassium permanganate activated alumina more suitable for continuous gas purification equipment.
The particle shape also affects the pressure drop of the equipment. When gas passes through the adsorbent bed, certain flow channels are formed between the particles. If the adsorbent contains a large amount of fine powder, or if the particles are too small, the gaps between the particles may become smaller, and the resistance to gas flow through the bed will also increase. For air purification equipment and industrial gas treatment equipment that need to operate for a long time, excessive pressure drop may increase the operating burden of the equipment. Therefore, when selecting potassium permanganate activated alumina, both pollutant removal performance and gas flow performance need to be considered. Spherical particles with an appropriate particle size can form a relatively stable bed structure.
The PURI-XR2006 potassium permanganate activated alumina produced by Zibo Xiangrun Environmental Engineering Co., Ltd. is a spherical particle product developed for such industrial gas purification needs. PURI-XR2006 uses activated alumina as the carrier and is loaded with potassium permanganate, enabling the product to utilize the porous structure of activated alumina and the oxidation capability of potassium permanganate to treat target pollutants. The product is available in various particle sizes, including 2–3 mm, 3–5 mm, 4–6 mm, and 5–7 mm, and the appropriate particle size can be selected according to different equipment bed designs, gas flow rates, and usage requirements.
For potassium permanganate activated alumina, spherical particles have another very important advantage, which is that they can meet the mechanical strength requirements for industrial filling. Adsorbents inevitably experience impacts and friction during transportation, handling, and filling. If the particles have insufficient mechanical strength, they are prone to breakage and pulverization. After the product is put into operation, long-term exposure to gas flow may also cause particle wear. Excessive dust not only affects the adsorbent bed, but may also increase system pressure drop and affect downstream filtration equipment. Therefore, when purchasing potassium permanganate activated alumina, industrial customers should not only focus on the KMnO₄ content, but also pay attention to the compressive strength and wear resistance of the particles.
PURI-XR2006 also places great emphasis on particle strength and usage stability during product design. Its typical parameters include a specific surface area of ≥200 m²/g, compressive strength of ≥50 N/piece, Al₂O₃ content of approximately 80%, KMnO₄ content of 4–12%, and bulk density of approximately 0.85–0.90 g/cm³. These parameters can reflect the product's structure and usage characteristics from different aspects. For air purification equipment and industrial gas treatment equipment that require long-term operation, potassium permanganate activated alumina with a stable particle structure is more convenient for transportation, filling, and maintenance.
