Catalyst Regeneration/Reactivation TRIZ Cases
- Spent Desulfurization Catalyst Remanufacturing Without Leaching Loss
Low-temperature heat treatment and dry-mixed calcination restore spent heavy oil desulfurization catalyst activity without leaching, washing, or drying.
- Hydroprocessing Catalyst Rejuvenation Without Post-Calcination
Regeneration plus metal-organic impregnation and drying restores spent hydroprocessing catalyst activity close to fresh performance.
- Catalyst Regeneration for Ammonium Salt Fouling in Hydrotreatment
In-situ flushing dissolves ammonium salt deposits during low-temperature hydrotreatment, preventing catalyst deactivation and reactor plugging.
- Recycled Hydrotreating Catalyst Shaping With Low Pressure Drop
Spent catalyst fines are milled, bound, shaped, and rejuvenated to restore activity while reducing waste and keeping reactor pressure drop acceptable.
- Catalyst Regeneration Loop Decoking for Coke-Fouled Heat Exchangers
Bypassing burn and calcination zones lets a catalyst regeneration gas loop recirculate oxygenated nitrogen to combust coke deposits with lower corrosion and gas use.
