Reliable Claus Performance

DEV SRC-L01 delivers strong catalytic activity for the core Claus reaction, driving the conversion of hydrogen sulphide into elemental sulphur with high efficiency. Its stable performance ensures plants can consistently achieve recovery targets under varying feed compositions and operating loads, providing reliability and compliance with stringent emission standards.

Improved Macroporosity & Mass Transfer

The catalyst is designed with a controlled macroporous structure, enhancing gas flow and diffusion within the particle. This improves contact between reactants and active sites, minimizing mass transfer limitations and enabling higher conversion efficiency. The result is consistent sulphur recovery and optimized performance even under high gas velocities or fluctuating loads.

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.

Operational Flexibility

DEV SRC-L01 maintains its effectiveness across different reactor designs, gas compositions, and temperature conditions. This catalyst has been proven in Standard Claus, Modified Claus, CBA, and MCRC processes, making it suitable for both main convertors and degassers. Its versatility simplifies operations, reduces inventory requirements, and ensures consistent results in diverse process settings.
