Types of Reactors 1.1

What is the primary characteristic of a batch reactor?

• Continuous feed and discharge

• Operates without feed or discharge during reaction

• Operates only in a steady state

• Requires a catalyst

In which type of reactor is the reactant concentration uniform throughout?

• PFR

• Batch Reactor

• CSTR

• Packed Bed Reactor

What type of reactor is typically used for high-pressure gas-phase reactions?

• Batch Reactor

• Packed Bed Reactor

• CSTR

• PFR

Which reactor is commonly used in small-scale production or laboratory studies?

• Batch Reactor

• CSTR

• Packed Bed Reactor

• PFR

What type of reactor is ideal for liquid-phase reactions requiring constant mixing?

• PFR

• Batch Reactor

• CSTR

• Packed Bed Reactor

Which reactor is most suitable for exothermic gas-phase reactions?

• Batch Reactor

• Packed Bed Reactor

• PFR

• CSTR

What is one major disadvantage of a batch reactor?

• Cannot handle multiple reactions

• Requires frequent loading and unloading

• Inefficient mixing

• Limited scalability

Why are CSTRs often used in industrial settings?

• High efficiency for reactions with heat transfer requirements

• No need for continuous operation

• Low energy requirements

• • Ideal for solid-phase reactions

In a PFR, the concentration of reactants:

• Remains constant

• Decreases along the length of the reactor

• Increases along the length of the reactor

• Fluctuates throughout the reactor

What is the role of a catalyst in a packed bed reactor?

• Reduces the pressure drop

• Increases reaction rate

• Prevents clogging

• Maintains uniform flow
