<P>PROBLEM TO BE SOLVED: To prevent thermal runaway in a compact type reaction apparatus for producing a desired fluid substance by a chemical reaction (catalyst reaction) of a fluidized substance mixture by using a catalyst installed in a narrow flow channel. <P>SOLUTION: The first to the third substrates 1-3 are layered in this order and housed in the first and the second outer plates 4 and 5. A first radiation transmission suppression film 14 of Au and a second radiation transmission suppression film 15 of YH<SB>x</SB>((x) is about 2) are formed in the inner faces of both outer plates 4 and 5. A first and a second temperature sensors 18 and 19 for monitoring thermal runaway are installed at prescribed two points in both outer plates 4 and 5. In the normal operation, since the first and the second radiation transmission suppression films 14 and 15 have approximately same radiation ability, both temperature sensors 18 and 19 detect the temperature of the outer faces of the both outer plates 4 and 5. In the case that thermal runaway occurs, since heat is transmitted only through the second radiation transmission suppression film 15, the temperatures detected by the temperature sensors 18 and 19 differ and based on it, a control circuit 20 transmits an emergency stop signal. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
