DEV-SRC T05 is a promoted high-titania Claus catalyst designed for maximum activity in sulphur recovery units. Engineered with specialized promoters and binders, it delivers exceptional hydrolysis of COS and CS₂, superior sulphation resistance, and long operational stability. This catalyst is particularly suited for units operating under stringent emission regulations, handling difficult acid gas feeds, or requiring extended cycles with minimal downtime.

  • High-titania composition for enhanced catalytic activity

  • Advanced pore structure to enable high space velocities

  • Strong resistance to sulphation and hydrothermal deactivation

  • Lasting mechanical strength for reliable operation

Exceptional Hydrolysis Efficiency

DEV-SRC T05 achieves near-complete hydrolysis of COS and CS₂, driving the Claus reaction toward equilibrium. This ensures higher sulphur recovery and compliance with stringent emission standards, even in units processing lean or challenging feeds.

Long Service Life Under Harsh Conditions

With robust resistance to sulphation poisoning and hydrothermal aging, DEV-SRC T05 maintains high activity over long cycles. This durability reduces change-out frequency and ensures dependable performance in reactors exposed to high temperatures or direct-fired reheaters.

Robust Durability

Manufactured on a mechanically strong and thermally stable alumina framework, the catalyst is highly resistant to crushing, attrition, and thermal degradation. This robustness allows it to withstand extended high-temperature operation without loss of activity, leading to longer run lengths, fewer unplanned shutdowns, and lower maintenance needs.

Capability for Direct Oxidation of H₂S

In addition to conventional Claus operation, DEV-SRC T05 is effective in SRUs utilizing direct oxidation processes. This versatility allows it to serve both traditional and advanced process schemes, providing refiners and gas processors with greater flexibility.

Advantages

  • Highest sulphur recovery efficiency

  • Extended operational cycles and fewer shutdowns

  • Flexibility for use across Claus and direct H2S oxidation SRUs

  • Lower downstream treating load due to effective COS/CS₂ conversion
