Product Advantages
A988 TiO₂-based sulfur recovery catalyst is our newly launched product with titanium dioxide as its primary active ingredient. Multiple proprietary additives are incorporated to greatly enhance comprehensive catalytic performance. We independently developed this A988 catalyst to match the operating parameters of imported sulfur recovery facilities.
A988 attains world-class standards in physical properties, chemical composition and catalytic activity. Its average crushing strength, thermal stability, hydrothermal stability and abrasion resistance all outperform imported counterparts. Industrial field tests verify that A988 delivers remarkably higher Claus reaction activity and CS₂ hydrolysis efficiency compared with overseas catalysts.
The main advantages of A988 TiO2 Based Catalyst are as follows:
• Excellent catalytic performance for organic sulfur hydrolysis and Claus reaction between H₂S and SO₂, with conversion close to thermodynamic equilibrium.
• Stable Claus and hydrolysis activity, free from performance degradation caused by oxygen breakthrough.
• High intrinsic activity, supporting high space velocity and enabling smaller reactor footprint.
• Extended service lifespan; avoids sulfate generation under fluctuating working conditions unlike conventional catalysts.

Application
Sulfur recovery is a vital process for natural gas plants and refineries. Raw feed gas generally contains H₂S, CO₂ and other components. Highly toxic H₂S will produce harmful SO₂ emissions if not handled properly. To meet strict environmental standards, sulfur compounds are converted into elemental sulfur and water via Claus sulfur recovery units and tail gas treatment systems.
This catalyst fits Claus facilities in petrochemical and coal chemical sectors. It can be fully packed alone in reactors or mixed with other functional catalysts. When loaded in primary reactors, it accelerates organic sulfur hydrolysis; placed in secondary and tertiary reactors, it elevates total sulfur conversion efficiency.
Benefiting from outstanding performance, A988 TiO₂ Based Catalyst is suggested for COS and CS₂ hydrolysis in the first reactor to lift Claus conversion in subsequent reactors. It can directly substitute imported catalysts on overseas-made equipment and be widely deployed on all sulfur recovery units.
A988 TiO₂ Based Catalyst adopts plastic-lined cardboard drum packaging, with 40kg net weight per drum. Keep it dry and isolated from other chemicals during shipment; rolling is forbidden. Under sealed storage, its quality remains intact for 3~5 years.
