We provide 'Microsphere Catalysts' in the range 300-1000um size (In addition to 1-10mm range spheres). Riogen has developed transition and noble metal supported 'Microsphere Catalysts' with alumina, silica, carbon, zirconia, titania etc as supports for applications in catalysis, adsorption and separation technologies. The surface area and pore volume of 'Microsphere Catalysts' are comoarable or higher when compared to regular spheres. We provide conventional single metal to custom multi-metal supproted catalysts with metal loading from 0.5 - 20 wt% or even higher.
