Several challenges can affect the efficiency of hydroisomerization:
Catalyst Deactivation: Catalysts can deactivate over time due to coke deposition, sintering of metallic sites, or poisoning by sulfur and other impurities. Selectivity: Achieving high selectivity towards the desired branched isomers while minimizing side reactions like cracking is crucial. Feedstock Variability: Variations in feedstock can affect catalyst performance and product distribution.
