Our company produces a new type of active alumina palladium plating catalyst. Due to the use of special carriers and special palladium plating processes, the active component particles of the catalyst are small and well dispersed. According to electronic scanning measurements, the metal palladium particles are distributed between 10-20A ℃. Therefore, this catalyst has high catalytic activity and can be used for deoxygenation of hydrogen, nitrogen, argon and other gases. At the same time, it can also remove organic sulfur, thiophene sulfur, and polyester, which is popular among users.
1、 Main indicators
1. Appearance: gray; Black spherical shape
2. Particles: Φ 2-3mm, 3-5mm
3. Palladium content: generally 0.3-0.5% (depending on the user)
4. Bulk density: 0.75-0.90g/m
5. Strength: Φ 2-3 ≥ 50N/particle, Φ 3-5 ≥ N/particle
2、 Usage performance:
1. It can be used at room temperature or at around 80 ℃, and the catalyst does not require regeneration treatment for long-term use
2. Airspeed can be selected within the range of 3000-10000-1:
3. The oxygen content in the raw gas is below 2%, and after catalytic deoxygenation, the residual oxygen content can be reduced to below 0.5ppm:
4. Catalysts generally have a service life of over 5 years.
3、 Usage:
1. This product has been reduced and activated before leaving the factory, and users do not need to undergo further reduction and activation treatment. It can be installed in a deaerator and used directly:
2. This product is packaged in two layers of plastic bags. If it has been stored for too long or has been exposed to moisture outside, the catalyst can be heated with hydrogen (maintaining a hydrogen gas velocity of 100hr-1 for 2-3 hours) after being loaded into the deaerator, and then put back into normal operation:
3. This product can be directly used for hydrogen deoxygenation. If used for deoxygenation of nitrogen or argon, an appropriate amount of hydrogen must be added to the feed gas and then catalyzed by a deaerator for deoxygenation. Excess hydrogen can be controlled within 0.5%.
4. If the deoxygenation effect of the catalyst decreases and cannot meet the requirements for use, the catalyst can be further treated by hydrogen heating treatment (hydrogen gas velocity of 100hr-1, temperature maintained at 200 ℃ for four hours).
4、 Attention:
When the catalyst is initially installed in the deaerator or or after long-term shutdown, it needs to be replaced with nitrogen and then supplied with hydrogen to ensure safe production.
