In catalytic systems, inert alumina ceramic balls serve as both bottom support layers and capping materials, playing a crucial role in supporting the catalyst, ensuring uniform distribution of gas and liquid flows, and protecting the reactor. Compared to ordinary ceramic materials, high-performance alumina ceramic balls—distinguished by their exceptional mechanical strength, high-temperature resistance, and chemical stability—have […]

I. What Are Inert Alumina Ceramic Balls? Inert alumina ceramic balls are an industrial ceramic material manufactured through high-temperature sintering, utilizing high-purity alumina as their primary raw material. They are typically employed at the bottom of reactors, within catalyst bed support layers, and in tower packing layers, serving primarily to: • Support the catalyst bed […]

I. Why do alumina catalyst supports pulverize and break? 1. Insufficient Mechanical Strength Alumina catalyst supports operate under high pressure, high flow rate, and continuous operation for extended periods. If the product itself lacks sufficient compressive strength, it is prone to: · Particle breakage · Edge wear · Surface pulverization · Bed collapse Some low-quality […]
