Type of Reactors 1.2

What is the primary feature of a packed bed reactor?

• Contains a fixed bed of catalyst particles

• Operates in a batch process

• Uses no catalyst

• Has uniform reactant concentration

Which reactor type is most suitable for reactions requiring long residence times?

• Batch Reactor

• PFR

• CSTR

• Packed Bed Reactor

What type of reactor is typically used for polymerization processes?

• Batch Reactor

• PFR

• CSTR

• Packed Bed Reactor

Why are packed bed reactors widely used in industrial applications?

• Low catalyst usage

• Simple design and scalability

• Continuous feed and mixing

• Uniform concentration of reactants

What is a key advantage of PFR over CSTR?

• Constant temperature

• Higher conversion per unit volume

• Easy to scale

• Uniform reactant concentration

What is one challenge in using packed bed reactors?

• Catalyst replacement is difficult

• Poor temperature control

For which reactor type is the residence time distribution (RTD) most uniform?

• Batch Reactor

• CSTR

• PFR

• Packed Bed Reactor

Why is back-mixing undesirable in a PFR?
