ChemBET TPR/TPD

Semi automated Chemisorption

Product Category: Chemisorption

Industry: Mining and materials, Particle and surface science

Supplier: Quantachrome

Description

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 Volumex

TPD DATA Screen
TPD Data Screen

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
