High pore volume and excellent resistance to attrition can now be obtained in a single catalyst carrier from Carborundum. New process techniques for spherical fluid-bed alumina carriers enable us to maintain large pore volume while actually lowering the rate of attrition. This family of fluid-bed carriers, with its wide choice of possible combinations of surface area, pore size and hardness, makes it possible to provide the specific carrier required for the optimum performance of your reaction.
