Activated Alumina Rods feature stable specific surface area, good compressive strength, low wear, suitable pore structure, low impurity content, and excellent impregnation of active components. They can be produced to meet customer requirements for catalyst carriers with different crystal phases, pore sizes, impurity contents, and appearances, such as rod-shaped, clover-shaped, multi-leaf shaped, hollow, and Raschig ring shapes. They are widely used in petrochemicals, hydrodesulfurization, and low-activity catalyst carriers.
