• Product yields

These parameters are monitored and controlled through a combination of instrumentation and process control systems. The operator must have a thorough understanding of the process and the control systems in order to maintain stable operation.

2. Describe the role of the catalyst in a Cat Cracker and how it is regenerated.

Function of the catalyst

• The catalyst in a Cat Cracker is a solid material that provides a surface for the chemical reactions that convert the feedstock into products.
• The catalyst is typically a zeolite, which is a porous material with a high surface area.
• The catalyst is circulated through the reactor where it comes into contact with the feedstock.

Regeneration of the catalyst

• Over time, the catalyst becomes deactivated due to the accumulation of coke and other contaminants.
• To maintain catalyst activity, it must be regenerated.
• Regeneration is typically carried out by burning off the coke in a separate reactor.
