Common Impurities andTheir Effects

Mechanizmy deaktywacji

Catalytt deactionation proceeds thugh seral pathways: poitoning (strong adsorption of impurities), coking (carbon deposition blocking pores), sintering (loss of activee metal surface area at high temperatures), and fouling (physical blocking by seculates). Lower-quality feed assocreate all of these. For exasple, booty cride with high asfaltene content causes rapise pore occlusion in if fixed hydrotherapers, requiring eltind forexed for catalysd.

Economic models show that a catalist deactivating twice as faST can increase operating costs by 30- 60% due to more frequent changeouts, lost production, and disposal fees. Therefore, catalist innovation musct adors both the root causes of deactivation and enable longer run lengths undepender harsh conditions.
