IRON CATALYST:
- developed a catalyst formulation that loses less than 1% activity per week.
COBALT:
- rapid initial deactivation followed by period of slower deactivation.
WAX/SLURRY SEPARATION
COBALT CATALYST:
IRON CATALYST:
- no problem with low molecular weight products. Severe problems with high molecular weight products because of catalyst attrition.
IRON CATALYST ATTRITION:
- defined mode as gradual erosion of surface rather than particle fracture.
