5 Zeochem Z10-02 Air Prepurification Grade – CO2 Adsorption Statistics in 1999

6 Zeochem Z10-02 Air Prepurification Grade–CO2 Adsorption Statistics in 2001/2002

7 Zeochem Z10-02 Comparison of CO2 Adsorption on 13X Types

8 Zeochem Z10-02EP A New Generation Product For APP and PSA O2 Applications

9 Zeochem Z10-02 CO2 Breakthrough Time
Test tubes: mm diameter/400 mm bed height Approx. 200 g molecular sieve Temperature: 25°C Operating Pressure: 6 bar absolute Test gas: 450 ppm CO2 in 2400 Nl/h nitrogen Breakthrough time: minutes to 5 ppm CO2 at outlet

10 Zeochem Z10-02 CO2 Breakthrough Time

11 Zeochem Z10-02 Density Advantage
Density of Z10-02 is higher giving more capacity per unit volume in existing plants Z10-02 density = 660 kg / cu meter Competitive density = 615 kg / cu meter Advantage = 7.3 %

12 Zeochem Z10-02 Competitor 1/8" Pellets, Zeochem 2.5 - 5 mm Beads

13 Zeochem Z10-02 Air Prepurification Grade
Crush Strength Physical strength of bead/extrudate under compressive stress Test measures the force required to crush beads/extrudates Simulates the compressive forces acting on the material in service All Z10-02 manufacturing lots are tested for crush strength to ensure long life in the field

14 Zeochem Z10-02 Air Prepurification Grade
Crush Strength Zeochem’s proprietary bead forming and calcination processes yield exceptionally high crush strength, typically in excess of 2.5 kp for 1.6 – 2.6 mm beads Spherical beads give a higher packed bed crush strength than comparable extrudates, since compressive forces are distributed more evenly Spherical beads have no sharp edges (cylindrical extrudates do) which can easily break off

15 Zeochem Z10-02 Air Prepurification Grade
Attrition Tendency for material from bead/extrudate to attrit from friction against other beads or surfaces Test measures the amount of fines produced by attrition Simulates the movement of beads/extrudates against each other during thermal swings All Z10-02 manufacturing lots are tested for attrition strength to ensure long life in the field

16 Zeochem Z10-02 Air Prepurification Grade
Attrition % material lost as fines* Zeochem Z – 2.6 mm bead 0.05 Competitor 1/16" extrudate In Zeochem standard attrition test (method Si5/45)

17 Zeochem Z10-02 Air Prepurification Grade
Hydrothermal Stability Ability of the material to maintain high adsorption capacity after exposure to high heat and humidity Test measures the retained capacity after accelerated aging in a hot, humid environment Simulates the loss in crystallinity resulting from thermal regeneration cycles to which the material is exposed in operation Z10-02 manufacturing runs are tested for hydrothermal stability to ensure long life in the field
