The wide application of activated alumina as a catalyst carrier is attributed to its porosity, high dispersion and excellent thermal stability. However, with the development of modern chemical reactions towards "harsh conditions" of high temperature, high pressure and high space velocity, traditional carriers often encounter problems such as insufficient mechanical strength leading to pulverization, high impurity content causing catalyst poisoning, and single pore structure resulting in uneven distribution of active components.
The R&D team of Zibo Xiangrun Environmental Engineering Co., Ltd. has overcome technical challenges and launched a new series of activated alumina carrier products based on the concept of "high efficiency and high performance". This series of products has the following core advantages:
1. Ultra-high purity ensures the activity of the main catalyst
Impurities, especially excessive sodium and iron content, can seriously affect the dispersion of precious metal catalysts and trigger side reactions. Our catalyst carriers strictly control impurity content, effectively reducing the risk of catalyst deactivation, and are particularly suitable for hydrogenation, dehydrogenation, and fine chemical reactions that are highly sensitive to impurities.
2. Excellent mechanical strength and wear resistance
In response to the huge pressure endured by fixed-bed reactors and the severe wear of fluidized-bed reactors, Zibo Xiangrun's carriers optimize the crystal phase structure to ensure that the crushing strength exceeds industry standards. This means that during the long-term operation cycle, the problem of increased bed pressure drop caused by carrier pulverization can be effectively avoided, significantly extending the operation cycle of the device and reducing the loss of catalyst replacement during shutdowns.
3. Optimized pore structure
No longer limited to traditional single pore diameters, it achieves gradient distribution control from micropores to mesopores. Pore volume and specific surface area can be customized according to the loading amount of the customer's active components. If a specific pore size distribution is needed to avoid diffusion limitations, we can provide precise solutions.
4. Thermal stability under harsh conditions
During high-temperature reactions or frequent catalyst regeneration, alumina carriers are prone to crystal phase transformation, leading to a sharp decline in specific surface area. Our carriers have significantly improved thermal stability and can maintain the stability of the γ phase at extremely high temperatures, ensuring the long-term operation of the catalyst.
