describing four AERO* Specialty Catalysts

The most active and stable catalysts made . . .

• For Hydrogen Production

• by Methane-Steam Reforming

• by Water-Gas Shift Reaction

• For Ammonia Synthesis

These catalysts represent the latest advances in catalyst manufacture and are the result of exten­sive product engineering. To assure the catalyst user optimum operating efficiency at all times, these five general properties have been built into the AERO Specialty Catalysts. 1. High catalytic activity. 2. Stability of high activity through long periods

of use. 3. High physical strength for greater resistance

to physical breakdown. 4. Optimum pellet size and shape to insure low

pressure drop through catalyst bed. 5. Low bulk density and low volumetric cost. The booklet contains Chemical and Physical Prop­erties and Operating Characteristics for each of
