Abstract
A design of a metal reactor equipped with gas in- and outlet tubings a nd IR transparent windows is described. The IR cell approximates a wel l-stirred tank reactor and is suited for in situ kinetic investigation s of catalytic reactions. While the catalyst, in contact with the reac tants and products, is analyzed in situ by means of time-resolved FT-I R spectroscopy, the effluent gas stream is analyzed by gas chromatogra phy mass spectroscopy. The reactor operates at temperatures up to 870 K; for applications of temperature-programmed desorption/reaction, lin ear heating rates between 1 and 20 K/min can be realized. Examples for applications are given.
