It can be used as precious metal catalyst carrier as well as special carrier agent carrier in chemical field, which can form special shell row structure during impregnation and effectively improve the reaction performance.
Aluminium carbide catalyst carrier (spherical, strip)
Product Performance:
This series of products have the characteristics of stable specific surface area and pore volume, good mechanical strength, low abrasion, suitable pore structure, low impurity content and good impregnation characteristics of active components. According to the requirements of users, we can adopt different process conditions to produce catalyst carriers with different phases, different pore diameters, different impurity contents and different shapes.
Main uses:
This product is widely used as catalyst carrier in petrochemical field, such as hydrogenation and refining, sulphur-resistant change. The shapes are spherical, strip, cloverleaf, multileaf cloverleaf, hollow and lassie ring.
