General Services VOC Technical Services

Our catalyst testing lab serves dozens of US customers operating regenerative and recuperative catalytic oxidizers. The core test program comprises:

  • Activity testing: The tests are performed in well-determined isothermal operations in a continuously stirred tank reactor. This insures high data consistency and simple and direct calculations for VOC oxidation rate, enabling prediction of oxidizer performance within the area of inlet parameters overlapping the experimental.
  • Contamination testing: The selected method, Scanning Electron Microscopy / Energy Dispersive X-Ray Spectrometry (SEM-EDXS) identifies chemical elements over the surface layer, 1-2 microns deep, and provides for semi-quantitative composition data including catalyst contaminants such as silicon.
  • Catalyst regeneration: The lab regeneration via washing or heat treatment determines optimal procedure for restoring the activity of used catalyst that effectively increases the catalyst service time.
  • Oxidizer performance evaluation: The oxidizer performance is found indirectly via a mathematical model that incorporates ratios between aged and fresh catalyst activities determined in sample testing, as well as basic information about the oxidizer including catalyst quantity, emission air flow rate, operating temperature, etc.
