What are the Challenges Associated with Coke Removal?
While coke removal techniques are effective, they come with their own set of challenges:
Thermal Damage: High temperatures used in thermal regeneration can sometimes damage the catalyst structure, leading to reduced lifespan and effectiveness. Incomplete Removal: Some methods may not fully remove the coke, leaving behind residues that can continue to impair catalyst performance. Environmental Concerns: The oxidation process can produce harmful emissions such as CO and NOx, necessitating additional treatment steps to mitigate environmental impact. Cost: The regeneration process can be costly, both in terms of energy consumption and operational downtime.
