506HL Deoxidation Catalyst – Alumina Support, Classic Technology, Reliable Choice
Release time:
Aug 28,2026
In the selection of gas purification catalysts, customers often face a trade-off: stable performance, cost-effectiveness, simple operation, long service life, and maintainability. Dalian Sanda Gas Purification Technology Co., Ltd.'s 506HL deoxidation and dehydrogenation catalyst is a classic product designed to address all these requirements.
506HL adopts the technical route of active alumina supported palladium. This system has been stably applied in the industry for many years, mature and reliable, with no technical risk. It requires no complex pretreatment; it starts working immediately when feed gas is introduced at room temperature.
The 506HL catalyst exhibits excellent comprehensive performance under conventional operating conditions:
· Broad operating conditions: can be put into use directly at room temperature, working pressure ≤20 MPa, space velocity ≤5000 hr⁻¹, applicable oxygen content ≤4%.
· Excellent purification effect: residual oxygen after purification ≤1 ppm, meeting the purification specifications for most industrial gases.
· High mechanical strength: particle strength ≥80 N/grain, not easy to pulverize.
· Long service life: ≥3 years under normal operating conditions.
· Regenerable: if deoxidation performance declines or activity decreases due to moisture, it can be heated in hydrogen or inert atmosphere for dehydration treatment to restore activity and be reused, significantly reducing long-term operating costs.
The 506HL catalyst is easy to use: evenly load the catalyst into the reactor, replace the air in the system with nitrogen, and then introduce the gas to be purified to start operation. No complex pretreatment or activation procedures are required, greatly reducing the operational threshold and maintenance difficulty – for production lines, the simpler, the more reliable.
Regarding the choice between 506HL and 506HT
Our company offers both 506HL (alumina support) and 506HT (titanium support). The former is suitable for conventional conditions, cost-effective, regenerable, and meets the needs of most industrial gas purification; the latter is suitable for harsh conditions involving high temperature (up to 650°C), sulfur/chlorine/ammonia, etc., with longer service life. Each has its own strengths, and customers can choose according to their own process conditions.
The 506HL deoxidation and dehydrogenation catalyst, with its mature and reliable technology and solid and stable performance, continues to serve customers in many industries such as petroleum, chemical, metallurgy, electronics, pharmaceuticals, steel, building materials, etc. It is a practical and trustworthy choice for your conventional operating conditions.
