Several challenges are associated with SMR catalysis:
Carbon Deposition: Carbon formation on the catalyst can lead to catalyst deactivation. This is mitigated by maintaining a high steam-to-carbon ratio and using additives like magnesium oxide to inhibit carbon formation. Sulfur Poisoning: Sulfur compounds in the feedstock can poison the nickel catalyst, reducing its activity. Pre-treatment of the feedstock to remove sulfur is essential. Thermal Management: Efficient management of the endothermic heat requirements is crucial. This is achieved through optimized reactor design and heat integration strategies.
