Table of Reactor Types and Characteristics
Type | Applicable Reactions | Advantages and Disadvantages
--- | --- | ---
Stirred Tank | Liquid-phase, liquid-liquid, liquid-solid phases | Wide applicability, high operational flexibility; easy control of temperature and concentration; uniform product quality
Pipe Reactor | Gas-phase, liquid-phase | Low mixing; small reactor volume; large specific heat transfer area
Empty Tower or Stirred Tower | Liquid-phase, liquid-liquid phases | Simple structure; mixing degree depends on height/diameter ratio and stirring; large axial temperature difference
Bubbling Tower or Baffle Bubbling Tower | Gas-liquid phase, gas-liquid-solid phase | Low gas-phase mixing; high liquid-phase mixing; easy temperature regulation; high gas pressure drop; limited flow rate
Packed Tower | Liquid-phase, gas-liquid phase | Simple structure; low mixing; low pressure drop; temperature gradient present; difficult to install and remove packing
Plate Tower | Gas-liquid phase | Counter-current contact; low gas and liquid mixing; limited flow rate; heat transfer surface often required if needed
Spray Tower | Gas-liquid phase, rapid reactions | Simple structure; large liquid surface area; residence time limited by tower height; limited gas flow rate
Fixed Bed | Gas-solid phase | Low mixing; low catalyst usage; resistant to wear; difficult to install and remove; difficult to control heat transfer and temperature
Fluidized Bed | Gas-solid phase, especially for reactions where catalyst deactivation occurs quickly | Good heat transfer; uniform temperature; easy to control; high catalyst efficiency; significant wear; high mixing; unfavorable for conversion rate; many operational constraints
Moving Bed | Same as above | Low solid mixing; high variability in solid-to-gas ratio; large temperature gradient within the bed; difficult to adjust
Trickling Bed | Gas-liquid-solid phase | Little catalyst loss; easy separation; uneven gas-liquid distribution; difficult temperature control
Heat Storage Bed | Gas-phase, using solid phase as heat carrier | Simple structure; wide adjustment range; frequent switching; large temperature fluctuations; low yield
Nozzle Type | Gas-phase, liquid-phase with rapid reactions | Fast heat and mass transfer; good fluid mixing; easy quenching of reactants
