Active site poisoning and thermal degradation during dehydrogenation and oligomerization. Restoring catalytic productivity extends operational lifecycles.

The focus on molded bodies and specific preparation methods addresses the physical breakdown and structural instability of catalyst particles during high-pressure gas-phase reactions. Improving structural integrity prevents pressure drops and extends reactor operational lifespan.

Hydrocarbon conversion processes suffer from rapid loss of catalytic activity due to carbon deposition or thermal instability. Preventing this degradation ensures continuous synthesis gas production and operational longevity.

Thermal and chemical fluctuations during reactor shutdown cycles cause irreversible catalyst deactivation and sintering. Mitigating this degradation extends the operational lifespan of the epoxidation system and reduces downtime for catalyst replacement.

The keywords explicitly highlight the need for mechanically stable catalysts during the hydrogenation of fatty materials. Preventing structural breakdown or attrition during high-pressure processing ensures consistent flow and catalyst longevity.

Incomplete conversion and side reactions during gas-phase oxidation reduce yield. Improving selectivity prevents the formation of unwanted byproducts like carbon dioxide.
