Novel design of a microstructured reactor allowing fast temperature oscillations

چکیده
Two types of stainless steel microstructured reactors for catalytic gas-phase reactions have been developed and characterized with respect to heir thermal behaviour under non-stationary temperature conditions. One of the reactors used (FTC-I) allowed periodic temperature changes up to 00 K with a frequency of 0.05 Hz. However, a broad temperature gradient of 80 K developed inside the reactor. A second reactor (FTC-II) enabled eriodic temperature variations of maximum 60 K with a frequency of 0.06 Hz while avoiding temperature non-homogeneity. The CO oxidation aken as a test reaction was carried out over a Pt/Al2O3 catalyst in the FTC-II reactor. In this way it was possible to study the effect of non-stationary emperature conditions on the reactor performance. A significant increase in CO conversion was observed with periodic temperature cycling as ompared to values obtained under steady-state conditions. 2007 Elsevier B.V. All rights reserved.

متن کاملThe influence of natural convection on the temporal development of the temperature and concentration fields for Sal’nikov’s reaction, P A B, occurring batchwise in the gas-phase in a closed vessel
Sal'nikov's chemical reaction is very simple; it consists of two consecutive first-order steps, yielding a product B from a precursor P via an active intermediate A, in P→A→B. The first of these steps is assumed here to be thermoneutral, with zero activation energy, whilst the second step is taken to be exothermic with a positive activation energy. These properties make this reaction one of the...
