摘要： PROBLEM TO BE SOLVED: To surely detect generation of gases, even when gas components are difficult to predict.
SOLUTION: When frequency signals from an oscillation circuit 1 are respectively applied to a measurement cell 10det, to which a sample gas is introduced and a reference cell 10ref, to which a reference gas is introduced, sound waves corresponding to the signals are generated and receiving signals are converted into electrical signals Fdet and Fref to output them. The sound wave propagation lengths of two cells are identical, and the sound velocities of the sample gas and the reference gas are set equal in the initial state. Changes in the gas component of the sample gas result in a phase difference between the signals Fdet and Fref because of a change in the sound velocity. A sampling-hold circuit 4 detects the phase difference, and by using pulses synchronized with the signal Fref from a pulse oscillation circuit 3 as sampling pulses and then sampling saw-tooth waves that are synchronized with the signal Fdet from a saw-tooth oscillation circuit 5, generation of gas is detected. By making the two cells identical in the temperature environment, influence due to changes in the temperature can be prevented.

摘要： PROBLEM TO BE SOLVED: To economically recover hydrogen of high purity from pyrolysis gas such as biomass by a method of a relatively simple constitution in which the consumption of expensive utilities such as electric power and town gas is suppressed, and operation troubles are reduced. SOLUTION: Reducing gas produced by the thermal decomposition of organic matter such as biomass is fed to the anode side of a high temperature water vapor electrolytic cell using a solid oxide electrolyte as a diaphragm. Oxygen ions are reacted with the reducing gas at the anode side of the electrolytic cell to cause the concentration gradient of the oxygen ions. Thus, the electrolytic voltage required for the decomposition of water is reduced, and hydrogen of high purity is obtained with the reduced consumption of electric power. COPYRIGHT: (C)2004,JPO
