Hydrogen Removal Catalyst for Oxygen Stream, Precious Metal Catalyst for Oxygen Purification

ZX-12 Oxygen Dehydrogenation Catalyst for High-Purity Oxygen Purification

Product Overview

ZX-12 Oxygen Dehydrogenation Catalyst is designed to remove hydrogen impurities from oxygen streams, including cylinder oxygen produced by water electrolysis and oxygen generated by air separation.

The catalyst promotes the reaction of hydrogen with oxygen to form water. The resulting water can then be removed through a downstream dehydration process to obtain high-purity oxygen.

ZX-12 is particularly suitable for oxygen purification in the semiconductor and optical fiber manufacturing industries. It can also be used in electronics, chemical processing, metallurgy, and other industrial applications requiring high-purity oxygen. In addition, it is applicable to the removal of hydrogen from oxygen-containing waste gas streams.

The catalyst has received the Third Prize of the National Invention Award, as stated in the product's original technical information.

Key Features

• Effective hydrogen removal: Catalytically converts hydrogen impurities in oxygen streams into water.

• High-purity oxygen production: Works with downstream dehydration equipment to support the production of high-purity oxygen.

• Low-temperature operation: Designed for operation from ambient temperature to 80°C.

• Broad operating pressure range: Suitable for atmospheric pressure to 2.0 MPa.

• Industrial applications: Suitable for oxygen purification in semiconductor, optical fiber, electronics, chemical, and metallurgical industries.

• Waste gas treatment: Can also be used to remove hydrogen from oxygen-containing waste gas streams.

Technical Specifications

Working Principle

The ZX-12 catalyst promotes the reaction between hydrogen and oxygen, converting hydrogen impurities into water:

2H₂ + O₂ → 2H₂O

The water formed during the catalytic reaction is subsequently removed by a dehydration unit. This combination of catalytic dehydrogenation and downstream dehydration enables the production of high-purity oxygen.

Typical Applications

• Semiconductor manufacturing: Purification of oxygen used in semiconductor production processes.

• Optical fiber manufacturing: Removal of hydrogen impurities from oxygen used in optical fiber production.

• Electronics industry: Oxygen purification for applications requiring high-purity process gas.

• Chemical industry: Hydrogen removal from oxygen-containing process gas.

• Metallurgical industry: Oxygen purification for industrial applications.

• Oxygen-containing waste gas treatment: Catalytic removal of hydrogen from oxygen-containing exhaust gas streams.

Application Notes

For optimal performance, the catalyst should be used in a suitably designed reactor and operated within the specified temperature, pressure, space velocity, and reactor geometry ranges.

The catalytic reaction produces water, so a downstream dehydration process is required where high-purity oxygen is the target product. Actual outlet gas quality depends on feed-gas composition, operating conditions, reactor design, and the performance of the dehydration system.
