Catalyst Regeneration/Reactivation TRIZ Cases
- Diffusive Catalyst Loading on Coal for Methane Gasification
A diffusive catalyst loading process disperses metal ions within the coal matrix through ion-exchange and supercritical fluid treatment.
- Hydrotreating Catalyst Rejuvenation via Citric Acid Impregnation
A hydrotreating catalyst rejuvenation process uses citric acid impregnation to restore metal oxide dispersion and catalytic activity.
- Hydrotreating Catalyst Rejuvenation via Gluconic Acid Treatment
Gluconic acid treatment redisperses hydrogenation metal components on used hydrotreating catalysts to restore catalytic activity.
