Alumina based Catalyst Carriers

Bairui offers a variety of spherical porous carriers to fully meet the needs of heterogeneous catalyst manufacturers. XWe use a unique and controlled manufacturing process to produce catalyst carrier spheres, providing suitable carriers for many applications.

Bairui can supply an appropriate sphere. Vast experience allows our in-process and post treatments to alter and tune-in density, pore structure, activity and thermal stability.
