Want tbe answer to low Cost
HE answer is, let Porocel Corporation Tyour catalyst on activated bauxite.
put
Our carrier—Porocel—with a price range of 2V2 to 4Vi cents per pound, costs much less than other supports (frequently high-priced synthetic materials). Its rugged, granular character eliminates the need for costly forming steps—permits direct impregnation by simple, inexpensive techniques. The result is savings of 20-50% in initial cost of the readyto-use catalyst. Porocel is inert in the great majority of cases. The degree of purit\ T in low-iron, low-silica Porocel means almost complete freedom from unwanted side reactions. Hence, Porocel catalysts exhibit clean-cut reactions and long life. Result? Low unit operating costs. With a surface area of about 225 square meters
per gram and porosity averaging 55% of its total volume, Porocel is capable of adsorbing large quantities of many inorganic salts or other compounds. Impregnation of the active ingredient is uniform and widely dispersed over areas easily reached by gaseous and liquid reactants—most important in surface catalysis. Catalysts are made in mesh sizes ranging from 2/4 to 20/60 or in special grades when desired. And these tough, uniform particles withstand wide ranges of temperature, pressure and flow —stand uj> under severe handling. As pioneer developers of bauxite-supported catalysts, we have produced efficient materials for others. Now, let us show you how economically it can be done for you.
