Products

High performance modified alumina

  • Model：LAE, LAF, LAG
  • Features：The aluminum source is processed by a special process to ensure the purity and performance of activated alumina. After the modification of the rare earth lanthanum, the thermal stability of the activated alumina can be significantly improved. The product has suitable pore size, pore volume, optimal loading aid and precious metal, which is beneficial to enhance the catalytic effect. Advanced production technology and production equipment ensure that the products are stable and can meet the needs of customers and develop products that meet their needs.
  • Application：automotive, diesel, motorcycle exhaust purification catalyst; industrial organic waste gas purification and indoor air purification.
