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.
