How to encourage catalyst sprawl A glance through the microscope shows why this inert catalyst carrier can hold so much active mater i a l . T h e c a t a l y s t is spread on the available intricate surface which results in maximum amount of active material being exposed to reacting chemicals. Π Carborundum offers a com plete line of inert, c e r a m i c bonded crystalline materials that resist attrition. Select from: A wide choice
of materials including alumi num oxide, silicon carbide, silica, mullite. · A wide choice of shapes, por osities, structures. · A wide choice of sizes — f r o m p o w d e r to %-inch bonded granu lar pellets. Free test kit and brochure. A test kit w i t h s a m p l e s of m a n y types of material is avail able to users of catalyst carriers. Please write to us on your letterhead. Literature available on request. ®
