PURPOSE:To increase the reaction velocity and to prevent the deterioration of the performance of catalyst due to high temp. by introducing gaseous oxygen and the combustible gas cong. hydrogen atom, and impressing magnetic field on the surface of the catalyst. CONSTITUTION:The temp. of catalyst 8 is kept at least about 500 deg.C by energizing a heater 4, and the dry air contg. 100-6800ppm gaseous hydrogen is streamed through a reaction vessel 2. Oxygen O2 and hydrogen H2 are allowed to react thereby on the surface of the catalyst 8. The measured value of reaction velocity is taken as V0 when the magnetic field by a magnet 10 is not impressed. And then, the magnetic field having a specified density of magnetic flux is impressed by the magnet 10, and the reaction velocity is measured. The increased amount of reaction velocity is taken as V when the magnetic field having the density B of magnetic flux is impressed. The density B of magnetic flux is varied in the range of about -5.0T-5.0T. |
