ChemBET™ TPR/TPD

Chemisorption - Physisorption Analyzer

The ChemBET™ TPR / TPD is a semi-automated analyzer designed to perform comprehensive catalyst studies by these techniques:

Temperature Programmed Reduction
Temperature Programmed Desorption
Temperature Programmed Oxidation
Pulse Titration
Physisorption for B.E.T. Surface Area and Pore Volume

The resulting data are used to:

Confirm or predict catalyst activity
Determine optimal catalyst preparation conditions for industrial use
Measure efficiency of regeneration of used catalysts
Quickly screen experimental catalysts
Calculate activation energies for a given reaction
Determine relative acid strengths

Sub-Ambient accessory

The accessory kit comprises a heat exchanger and special jacketed cell. Dry nitrogen gas passes through the heat exchanger in its own LN2 dewar and goes on to cool the sample cell. This inexpensive device is supplied complete with gas input line, flow regulator valve, stainless steel funnel (for filling LN2), dual thermocouple and furnace cover, in addition to the cell and dewar. Starting temperatures below -100 deg C are possible.
