Abstract
Disclosed are an apparatus and a method for carrying out and studying catalysis and catalyzed chemical reactions. Disclosed is a reactor with a catalyst zone, under vacuum, into which a very rapid pulse of reactant gas is pulsed. The products are analyzed by a real-time method of analysis, such as mass spectrometry. The apparatus and method can detect reaction intermediates and products, and can indicate their sequence of production.
Claims1
An apparatus comprising:
- (a) an enclosed housing and means for producing a vacuum within the housing;
- (b) within said housing, a reactor having a zone defined in the reactor containing a packed particulate reaction catalyst, said reactor being structured to allow a reactant gas to pass through the packed particles of the catalyst to produce a product gas by a slow reaction;
- (c) means for introducing a rapid pulse of said reactant gas to said reactor and means for controling conditions such that a given molecule of said gas will collide with the surfaces of said catalyst from about 100 to 10.sup.6 times and with other gas molecules about 10.sup.3 or less;
- (d) means for withdrawing from said reactor a pulse of product gas;
- (e) within said housing, means for resolving said pulse of product gas to produce a resolved pulse of product gas in which molecules of product gas move in substantially parallel paths;
- (f) means for providing real time analysis of said resolve pulse of product gas;
- and
- (g) means for coordinating the actions of said rapid pulse introducing means and said analysis means so that scanning by said analysis means coincides with the arrival of a resolved pulse of product gas.
