Technical Data
Typical values for key technical parameters.
| Catalyst | Application | CoO | MoO₃ | Appearance | Bulk density | Operating temp |
|---|---|---|---|---|---|---|
| RCAT®-4210 (Standard TGT) | Claus tail gas hydrogenation | min. 2% | min. 10% | Spheres or trilobe extrudate* | 550–750 kg/m³ | >280 °C |
| RCAT®-4211 (Low Temp TGT) | Low-temperature Claus tail gas hydrogenation | min. 2.5% | min. 12% | Spheres or trilobe extrudate* | 550–750 kg/m³ | As low as 220 °C |
* Different sizes available.
Application
Installed in the tail gas treatment reactor downstream of the Claus unit. Residual SO₂, COS, CS₂ and sulfur vapour are hydrogenated over the Co-Mo catalyst back to H₂S, which is recovered and recycled to the Claus plant, cutting stack emissions.
Key product capabilities and benefits
- RCAT®-4210 for conventional reheater temperatures above 280 °C
- RCAT®-4211 for low-temperature operation down to 220 °C, reducing reheat fuel consumption
