摘要： PROBLEM TO BE SOLVED: To provide a catalyst which inhibits the grain growth of a catalytic metal in a high temperature range and exhibits particularly high activity in a CO shift, reaction in a low temperature range in which shift from CO to H2 is advantageous in equilibrium theory. SOLUTION: The catalyst comprises a carrier containing at least one selected from rutile type titania, zirconia and ceria and a noble metal supported on the carrier. Since the carrier has high hydrophilic property and high H2O adsorbing property and the supported noble metal is liable to adsorb CO, the catalyst has enhanced activity in a CO shift reaction by the presence of large quantities of H2O and CO adsorbed on the surface.

摘要： PROBLEM TO BE SOLVED: To immediately analyze reaction with which multiple components participate by a constitution wherein an ionized gas is electrostatically accelerated in a prescribed direction and a mass number of ion of a reaction product is judged on the basis of time differences of ion arrivals. SOLUTION: A prescribed reaction gas is ejected in a pulse action from a pulse valve 31 for a prescribed time period to blow a surface of a specimen 9 during the operation of all of the vacuum pumps. A part of the reaction gas is absorbed to the surface of the specimen 9 to be activated and reacted so that a reaction produced gas is generated, then gradually desorbs from the surface of the specimen 9. A greater part of the gas that collides to the surface of the specimen and is reflected thereby is sucked from a discharge hole. The reaction produced gas that advances straight from the surface of the specimen 9 is passed to an analysis chamber 51. The reaction produced gas is ionized and accelerated in the analysis chamber 51 to reach an MCP via a flying time type mass analysis chamber. The mass is determined in accordance with the arrival time from the ionization to MCP and a relative quantity is measured based on the voltage. These measuring operations are executed by means of a digital oscilloscope and a measuring controller.
