<P>PROBLEM TO BE SOLVED: To provide a very safe and small environmental cleanup microreactor system capable of reducing ethylene oxide (EO) to 1 ppm or less, discharged from an EO-using sterilizer of a hospital or the like with a high performance and low cost. <P>SOLUTION: This system is provided with an air heating part 1 sucking air of the outside of an apparatus, heating it by a heater and sending at a constant flow rate; a gas mixing chamber 2 mixing toxic gas introduced from the outside of the apparatus with air sent from the heating part 1; and a catalytic reaction part 3 containing a three-dimensionally structured catalyst 32 having numerous fine passages structure with diameters of several to several hundred μm in a reactor 31, in which the mixed gas mixed in the mixing chamber 2 makes to contact with the catalyst while flowing and moving in the catalyst 32, to treat the toxic gas. The catalyst 32 has numerous fine passages (microchannels) with diameters of several to several hundred μm three-dimensionally crossing, joining or branching. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
