PURPOSE:To reduce the number of processes sharply by a method wherein granular catalysts having different compositions are filled up in a tube sequentially in the direction of the length of the tube, and the tube is heated, by a heater, selectively for each desired part thereof selected in the direction of the length of the tube, in a desired sequence. CONSTITUTION:Desired quantities of gases of carbon monoxide, hydrogen and helium are sent from the respective gas reservoirs 45, 46 and 47 through a stop valve 1 and a flowmeter 3 and mixed, and then a mixture gas thus prepared is sent into a reaction tube 11. A gas flowing out of an outlet 42 is separated into flows running into a gas chromatograph 4 and a mass-spectrometer 5, and the gases thus separated are analyzed thereby respectively. The results of two analyses are recorded in a recorder 6 respectively. Meanwhile, a heater 12 for heating the reaction tube, which has a temperature detector 13 incorporated therein, moves sequentially while heating a part of the reaction tube in the direction of the length thereof from the outside thereof. By comparing the speed of this movement with the speed of feeding of recording paper in the recorder 6, the location of catalysts in the reaction tube and the catalytic effects thereof can be known. |
