HYPERKAT – Hydrogen Peroxide Catalysts.

Catalytic Decomposition of Hydrogen Peroxide Catalysts (H2O2) in Air Flows

Catalytic Decomposition of Hydrogen Peroxide Catalysts (H2O2) in Air Flows

Chemical Decomposition Reaction of Hydrogen Peroxide

Hydrogen Peroxide strongly tends to decompose into water and oxygen, at that developing a great amount of heat according to the following formula:

2 H2O→ 2 H2O + O2+ 196.2 KJ

However at room temperature and temperatures < 60 degree C, the rate of decomposition is immeasurably low so that hydrogen peroxide is practically permanent (metastable) in air. By using suitable catalysts, the decomposition process can be accelerated strongly so that complete decomposition of the hydrogen peroxide into the components water vapour and atmospheric oxygen can be reached in an air flow already at room temperature.

OZONKAT – Ozone Catalysts.

Catalytic Decomposition of Ozone (O3) in Air Flows

Chemical Decomposition Reaction of Ozone

Ozone (Trioxygen O3) strongly tends to decompose into dioxygen (atmospheric oxygen O2), at that developing a great amount of heat.

2 O3 → 3 O2 + 285.6 KJ

The most characteristic property of ozone is its oxidizing power as a result of one of its 3 oxygen atoms.

 O3 → O2 + O

At room temperature and temperatures < 60 degree C, the decomposition will proceed gradually. By using suitable catalysts, the decomposition process can be accelerated strongly so that complete decomposition of the ozone (O3) into atmospheric oxygen (O2) can be reached in an air flow already at room temperature.

The Catalyst.

Our catalyst is a metal oxide mixture combined with an aluminosilicate in the form of pellets with the following characteristics:

  • Surface of the pellets with adsorptive effect
  • BET value: approx. 100 m²/g
  • High dimensional accuracy
  • High solidity of the pellets

The extremely high decay rate of the exhaust air to pass through is a result of the fineness of the pellets combined with the high adsorptive capacity of their surface.

The Catalyst Panel.

The catalysts are formed as a panel which is flown through by the hydrogen peroxide containing air flow.

The catalyst panel consists of aluminium profiles with embedded polished stainless steel wire cloth. The catalyst is available as pellets which are inserted into the catalyst frame. The catalyst panels are equipped on one or both sides with silicone rubber seals resistant to H2O2 .

Efficiency of the Catalyst Panel:

  • At input concentrations of H2Oup to 4000 ppm, the concentration of H2Oin the clean air flow will fall to < 0,1 ppm.
  • At input concentrations of O3 up to 1000 microgram, the concentration of O3 in the clean air flow will fall to < 30 microgram.

(1) Make sure that there will be no condensation of water in the catalyst because the condensate will cover the effective surfaces of the catalyst and render them ineffective.

Need another dimension?

Catalyst panels in other dimensions and forms (e.g. cartridges) are available on request.

Configuration.

The basic design of the system consists of a body with built-in pre-filter and catalyst panel. Fans have to be installed on suction side. Presently, we can offer you the following types of unit:

Small units up to 300 m3/h

Capacity: 1 catalyst panel KTP 300

Body: Consisting of ground stainless steel.

Large units up to 7200 m3/h

Capacity: 1-12 catalyst panel KTP 600

Body: A modified device of ventilation and air-conditioning meeting the quality standards of ventilation and air-conditioning.

Examples for large units.
