A958 Iron Oxide Sulfur Recovery Catalyst adopts special activated alumina as carrier with proprietary additives, delivering dual functions of Claus catalytic activity and deoxygenation protection. It features excellent Claus performance and effectively eliminates trace oxygen in process gas, shielding downstream catalysts against sulfation poisoning.
A958 can be packed independently in a single reactor or laid on top of activated alumina catalyst beds, taking up 1/2 or 1/3 of the total catalyst filling volume. Insensitive to fluctuating working conditions and excess SO₂/O₂ in feed gas, it is ideal for low-load facilities or units with frequent dramatic load variations. Under identical equipment and process parameters, the overall sulfur conversion rate can be boosted by around 1.7%. It is specially designed for sulfur recovery units with high H₂S concentration and wide feed flow fluctuations.
A958 has been widely applied in numerous industrial plants, and field operation data fully validates its superior comprehensive performance.

FAQ
Q: In which specific process stages of sulfur recovery is the A958 deoxygenation-protective sulfur recovery catalyst primarily employed?
A: It is mostly used in conventional Claus reaction systems to assist the conversion of sulfides in acid gas.
Q: How well does the A958 deoxy protective sulfur recovery catalyst tolerate common impurities in the feedstock?
A: It can resist common impurities in gas from refineries and coal chemical plants, adapting to many mainstream industrial scenarios.
Q: Can the A958 deoxy protective sulfur recovery catalyst be layered and loaded alongside other types of catalysts?
A: It can be loaded in layers with alumina, titanium-based and other catalysts according to process plans to form a composite catalytic system.
Q: What is the wear condition of the A958 oxygen-deactivation protected sulfur recovery catalyst after long-term operation?
A: Adopting mature forming technology, it has a low overall wear rate and rarely produces excessive dust after long-term use.
Q: How to determine whether the A958 deoxygenation-protected sulfur recovery catalyst can still function properly?
A: Check the sulfide conversion efficiency and bed resistance. It can be used continuously if all indicators are normal; replacement is recommended when obvious abnormalities occur.
