How porous do you want your
catalyst supports? Norton catalyst supports come in two types: 1. If your process calls for coated catalyst supports, you get what you want from Norton medium-porosity spheres. They have a porosity of 3035%, with a rough, open surface struc ture. This gives you maximum adher ence of catalyst to surface. 2 . If y o u need supports for im pregnation, N o r t o n h i g h - p o r o s i t y spheres are your choice. Their porosity is 42-47% with large, connected, internal pores uniformly dispersed throughout the support. This gives you maximum deposition of catalyst. You a l s o h a v e a choice of s i z e s a n d s h a p e s . Norton spheres are avail able in diameters of *A£ to 1".
