Deliver 2 trucks of activated alumina to South America
Time:2025-11-10
In the middle of this year, one of our customers sent us tender request for over 40 tons of activated alumina. It mentioned that they need to be used in the dryers of the catalytic reforming unit, to dehydrate of recycle treating gas.
After we checked the data, we found that the requested bulk density is over 800kgs/m3. For this point, based on our experience over years, our technical told that the data is impossible to achieve, even BASF BRAND. Last year, we also received similar project, which need molecular sieve, activated alumina and ceramic balls together. So when finished checking all information, we decided to design the loading diagram and operation procedure to customer, which could better understand and assit customer to deep talk with the end user.
During tender period, customer still have more questions for the adsorbent choosen, because end user use brand adsorbents before. Through many months’ communication, customer found we’re professional to solve the technical question and always provide some constructive suggestion to assit him to close the tender. In the final stage, after many months’ discussion, it’s nice that customer achieve order successfully.

Why does activated alumina have such a good effect in air dryers?
1. Excellent adsorption performance: Activated alumina has a porous structure (pore size 2-50nm) with a specific surface area of 300-330m ²/g, which can efficiently adsorb water. The dew point can be reduced to below -40 ℃, meeting the gas requirements of precision equipment.
2. Strong chemical stability: Its chemical properties are stable and do not react with gases in compressed air, avoiding secondary pollution.
3. High regeneration efficiency: After adsorption saturation, it can be regenerated by heating at 200-350 ℃ for recycling, reducing long-term operating costs.
4. Wide industrial applicability: Suitable for high and low temperature environments, with uniform particles that are not easily powdered, reducing the risk of blockage, and suitable for continuous production scenarios.
