Hydrocarbon Removal Catalyst for Oxygen Stream, Precious Metal Dehydrocarbon Catalyst for Oxygen Purification

ZX-104 Oxygen Dehydrocarbon Catalyst for High-Purity Oxygen Purification

Product Overview

ZX-104 Oxygen Dehydrocarbon Catalyst is designed for the removal of hydrocarbon impurities from oxygen streams, including cylinder oxygen produced by water electrolysis and oxygen generated by air separation.

The catalyst promotes the oxidation of hydrocarbons in oxygen streams, converting them into carbon dioxide (CO₂). The generated CO₂ can then be removed through a downstream adsorption process, helping to produce high-purity oxygen.

ZX-104 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 organic compounds 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 hydrocarbon removal: Catalytically converts hydrocarbon impurities in oxygen streams into carbon dioxide.

• Low residual hydrocarbon content: Designed to achieve a residual hydrocarbon content of ≤0.1 ppm under specified operating conditions.

• High-purity oxygen production: Works with downstream CO₂ adsorption equipment to support oxygen purification.

• High-temperature operation: Designed for operation at 300–400°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 organic compounds from oxygen-containing exhaust gas streams.

Technical Specifications

Working Principle

The ZX-104 catalyst promotes the oxidation of hydrocarbon impurities in oxygen-containing gas streams, converting them into carbon dioxide.

The generated CO₂ is subsequently removed through a downstream adsorption process. This combination of catalytic hydrocarbon removal and CO₂ adsorption helps produce high-purity oxygen.

Typical Applications

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

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

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

• Chemical industry: Removal of hydrocarbon impurities from oxygen-containing process gas.

• Metallurgical industry: Oxygen purification for industrial applications.

• Oxygen-containing waste gas treatment: Catalytic removal of organic compounds 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 CO₂ generated during catalytic oxidation must be removed by a suitable downstream adsorption unit where high-purity oxygen is required. Actual outlet gas quality depends on feed-gas composition, operating conditions, reactor design, and the performance of the downstream adsorption system.
