Ozone Destruct Catalyst:

Ozone Destruct Catalyst is used to safely break ozone down to oxygen in a process.  Ozone Destruct Catalyst is used in all major ozone destruct units manufactured today.  The Ozone Destruct Catalyst material is a true catalyst that will safely destroy ozone in process without breaking down.

Ozone Destruct Catalyst should be placed in a stainless steel container for ozone destruction.  During the catalyst process the catalyst material does generate some heat, therefore the container will increase in temperature during operation.  Using PVC or other plastic materials should be avoided as these may melt, and have the possibility of igniting and providing a flame source.

This catalyst is not a hazardous substance, therefore your spent Ozone Destruct Catalyst can be disposed of in a standard landfill.

Over time your catalyst will become contaminated and less useful to destroy ozone.  Due to this, we recommend you replace your ozone destruct catalyst annually.  Common contaminants that will poison your Ozone Destruct Catalyst are listed below:

- Sulfur compounds

- Halogenated compounds

- Hydrocarbons

- Metals

- Nox

- Silica

- Water (condensed water will destroy Ozone Destruct Catalyst)

Specifications: 

- Shape - Granule

- Mesh - 4-8

- Bulk Density = 0.7(+/-0.05) g/cc 

- Surface Area = ≥ 160-240 m2/g

- Appearance = Black/dark brown granular

Suggested operating conditions: 

- Vertically-oriented vessel with top-down air flow

- ≤ 5,000 hr -1 Gas Hourly Space Velocity

- ≥ 2.2 ft/sec (0.66 m/sec) Linear Velocity

- In humid applications pre-heat the air prior to the catalyst bed ~15º F (9º C)  above ambient temperature to prevent condensation of moisture on the surface of the catalyst.

 FAQ:

How long does the catalyst last?

• Catalyst life will be dependent upon contaminates and overall use. We recommend replacing catalyst annually to ensure continuous and reliable ozone destruction.

What shortens the catalyst life?

• Water condensing on the catalyst will damage the catalyst that water condenses on. This is why heaters and water traps are recommended on all applications where ozone is destroyed in moist air or ozone off-gas applications

• Hydrocarbons, VOC’s, Sulfer compounds, Halogenated compounds, Heavy metals, Nox, and Silica will all poison the catalyst and shorten the life.

Is there a shelf life for the catalyst? Can we buy a rebuild kit and keep it on the shelf?

• There is no shelf life for the catalyst. It will last indefinitely on the shelf. Store in cool, dry area in a closed container. Segregate from easily oxidizable materials.

Is the spent catalyst considered a hazardous material?

• The catalyst is not a hazardous substance, however, it should be handled with care. Protective equipment in handling including, safety glasses, and gloves should be used.

• Disposal of the catalyst in a standard landfill is approved after verifying that it is not contaminated with hazardous substances through usage.

This stuff looks like carbon, can we just use carbon material instead?

• While carbon will destroy ozone it is not a safe option.  The carbon + ozone reaction will generate heat during ozone destruction.  As carbon is a great fuel source and can burn it can ignite with the oxygen gas flowing through the carbon.  With a source of oxygen + carbon the fire will be extremely hot and could cause major destruction to the surrounding infrastructure.  Carulite, will not create this level of heat, and carulite will not burn.

• Carbon destruction of ozone is not a catalytic reaction.  Carbon + Ozone = CO and CO2.  Over time the carbon will become spent and will not destroy ozone safely.  

Do you offer repair/rebuild kits for other brands of destruct units?

• Yes we do. The Ozone Destruct Catalyst material used for catalyst material is the same in most all catalytic ozone destruct units. We can provide this catalyst, screens, gaskets, heaters, water traps and every part you might need. Contact us for details.
