Purpose
1. When making pure gases, a de-oxygenation catalyst is commonly utilized to remove remaining oxygen, thus guaranteeing the purity of gas.

2. If there is a trace amount of oxygen in synthesis gas, coal gas or coke gas, catalyst poisoning is very likely to take place during downstream processing. Given this, our gas deoxidizing agent is adopted to eliminate oxygen.

3. During oxygen purification, there is a small amount of hydrogen gas that should be dislodged, and our dehydrogenation catalyst is applicable at this time. In fact, the difference between a de-oxygenation catalyst and a dehydrogenation catalyst is that the former one is derived by the latter one through a reduction reaction.

Operating Condition
1. The deoxygenation of hydrogen gas or inert gas can be started up at room temperature, and the space velocity shall be within 3000-10000h^-1. Accordingly, the residual oxygen concentration will be lower than 1ppm, and even 0.02ppm is achievable.

2. For synthesis gas, coal gas and coke gas, our deoxygenation catalyst should work under certain conditions. More specifically, the temperature range is 110-140℃, the pressure is over 0.1MPa, and the space velocity is within 1000-4000h^-1. If so, the final oxygen concentration will not exceed 1ppm.

3. When it comes to dehydrogenation process, the dehydrogenation catalyst doesn’t need to be reduced before working, and it is started up at room temperature though the best operating temperature range is 80-120℃. With a space velocity of 1500-3000h^-1, our catalytic agent is able to reduce the hydrogen content of oxygen gas to 5ppm or lower. In addition, this metallurgy catalyst features good temperature resistance (650-750℃), high mechanical strength and long service life (3 years).

Application
Our de-oxygenation catalyst has found a great number of applications in different fields as listed below.
1. Gas purification factories
2. Synthesis gas, coal gas and coke gas refining plants in chemical industry
3. Gas purification systems used in float glass, color TV and electronic industries
4. Olefin refining plants in petrochemical industry: For example, when fabricating polyethylene and polypropylene, the oxygen concentration is required to be lower than 0.1ppm, because oxygen will decrease the activity of olefin catalyst as a result of chemical reaction between them, and simultaneously, it will also react with some reactants to produce resins that will block the pore structure of olefin catalyst.
