Keywords: Catalysis; Oxidation; Pyrolysis; Thermal Analysis.

Novel aspect: The new EGA-MS instrument with skimmer interface and IAMS is successfully applied to catalysis evaluation not only stable organic gases but unstable gases due to pyrolysis. It reflects real evaluation onto the industries.


The coupling apparatus with Skimmer interface and Ion Attachment Mass Spectrometry (IAMS) was applied to new evaluation of combustion catalysis using pyrolyzed organic gaseous species which included not only stable gases but unstable gases. This catalysis evaluation is expected to include influence of the deactivation by covering the surface with tar condensed and synthesized from pyrolyzed organic gases, although general evaluation uses methane gas as one of the most incombustible organic gas. The methane does not however cause any deactivation. Thus the new evaluation is possible to reflect a practical condition of the catalysis to organic gases pyrolyzed. In this study, the evaluation to organic gas evolved from PVA as a binder in starting material of alumina ceramics will be presented.
