Harshaw Stationary and Falling Catalyst Basket Reactor

Basket is a perforated tube that is installed in the bottom of a reactor

 
   

The catalyst basket is a perforated tube that is installed in the bottom of a reactor. The basket can be easily filled with supported (formed) catalysts and changed between batch runs.

 

The catalyst basket has a cruciform shape (similar to the Carberry). The catalyst basket is held in a catch near the top of the grooved agitator shaft in the gas/vapor phase during the initial part of the experiment. The basket releases when the shaft is stopped and momentarily reversed. This allows the catalyst basket to travel down the groove to the bottom position for the liquid phase of
the experiment.

FEATURES

  • Reactants:
    Gas/Vapor/Liquid/Solids.

  • Typical Reactions:
    Hydrogenation, oxidation, catalyst testing.

  • Maximum Allowable Working Pressure:
    5,500 psig (379 Bar)

  • Temperature:
    650°F (343°C)

  • Maximum Rotation Speed:
    Variable with the stage of the process and other considerations. 2,500 RPM is the maximum recommended if a) the basket is in the top position (in the gas phase) and b) the catalyst weight distribution is uniform. 1,000 RPM is the maximum recommended if a) the basket is in the lower position (in the liquid phase) and b) the cataylst weight distribution is uniform. Actual rotational speeds may need to be reduced further if catalyst weight distribution is not uniform.

  • Common Customizations:
    Conversion kits to convert an EZE-Seal™ or Bolted closure batch reactor into a Harshaw Falling Basket Reactor, special wire mesh size, special materials, specific pressure/temperature ratings, ASME code stamp, CE mark for Pressure Equipment Directive, and CRN.

  • Standard Material:
    316 Stainless Steel

 

BENEFITS

Corrosion resistant gradientless reactor is basic equipment for advancing the science of gas phase, solid phase, heterogeneous catalyst technology.
This high pressure laboratory apparatus can be used for diverse supported and selective catalyst research, including catalyst screening, catalyst characterization, and surface chemistry studies. The leak-free metal gasket design provides bench-scale catalytic synthesis capability for scientific experimentation.
