摘要： An unreacted gas detector including a reactor unit for producing a target gas by way of reacting material gases in its reaction chamber, a sensor body connected to the reactor unit, a measurement space provided in the sensor body for allowing the target gas to flow, an unreacted gas sensor having a temperature measurement section covered by a catalyst layer and disposed inside the measurement space, and a target gas sensor with its temperature measurement section disposed in the sensor body. Any unreacted gas remaining in the target gas is reacted by the catalyst layer so that a resulted temperature change is detected by the unreacted gas sensor, and a target gas temperature is measured by a target gas temperature sensor, thus finding an unreacted gas concentration from a temperature difference between the temperatures obtained by the unreacted gas sensor and the target gas temperature sensor.

摘要： A calorimetric sensor is described, in which a bimetallic lever (21, 22) is combined with a chemical sensing layer (23), e.g. a catalyst, and a sensitive device (6) to determine any deflection of the bimetallic lever. Due to its high sensitivity, the new sensor is applicable in various technical fields.

摘要： Carbon monoxide contained in reformate gas is removed by a preferential oxidation reaction in a catalyst, two preferential oxidation reactors (20A, 20B) being disposed in series. Valves (7, 8) supply air containing oxygen as an oxidizing agent individually to these preferential oxidation reactors (20A, 20B). Temperature sensors (9, 10) detect the catalyst temperatures of the preferential oxidation reactors (20A, 20B), and a controller (5), by adjusting the flow rate of the valves (7, 8) based on the detected temperatures, maximizes the carbon monoxide removal performance of the preferential oxidation reactors (20A, 20B), while preventing excessive catalyst temperature rise.

摘要： A microcalorimeter includes instrumentation for reducing measurement errors due to system fluctuations. One or more sensors is utilized to detect heat content of a sample gas, and create a composition independent system. Instrumentation for automatically compensating for pressure and temperature variations is also employed in the microcalorimeter. A method for continuously measuring the BTU content of a gas utilizing the microcalorimeter includes steps for adjusting system parameters in response to changes in ambient conditions and sample gas composition to further reduce measurement error.

摘要： A novel catalytic gas calorimeter system and method. The system comprises a catalytic reactor which includes a catalyst capable of oxidizing the sample gas. The catalyst is configured within the reactor so as to maximize the catalyst surface area available to the sample gas, such as, for example, by depositing the catalyst on a bed of small beads of porous surface structure or on a porous monolithic substrate. The reactor temperature and space velocities are maintained at a level which will ensure substantially complete oxidation of the sample gas. The catalytic reactor of the present invention is surrounded by one or more temperature shields to isolate the reactor from the surrounding environment. A sensor device is positioned within the reactor to measure the temperature within the reactor. The calorimeter system also includes means for measuring and controlling the volume of gas and air entering the catalytic reactor and means for measuring the relative humidity of the gas stream leaving the catalytic reactor. These measurements are then used to calculate the net heating value (NHV), gross heating value (GHV) and the specific gravity of the sample gas under consideration.
