THEORETICALLY IMPREGNATED MOBILITY AND STEERED THERMOCATALITIC METHOD FOR THE DUE TO HEAT OF BURNING OF NATURAL GAS
Abstract
The possibility of using a thermochemical detector to determine the heat of combustion of natural gas has been theoretically substantiated. It was found that the degree of combustion of combustible gases in thermochemical gas analyzers based on measuring the temperature of combustion products depends on the volume and type of catalyst, the flow rate of the analyzed gas and the concentration of combustible gases in it, as well as on the temperature, determines the need to ensure a greater degree of combustion of combustible substances. selection of the catalyst layer thickness, its activity, temperature and determination of the permissible concentrations of the components in the gas stream. The use of a pulse mode of operation in gas analyzers with thermocatalytic converters will ensure the constancy of the volumetric flow rate of the analyzed gas into the detector, is a decisive factor in ensuring the accuracy of measuring the thermal effect of catalytic combustion; carry out the process of catalytic combustion at low concentrations of combustible components in the flow of the carrier gas (air) by selecting the sample volume, is introduced into the analyzer, which can ensure the stability of the catalyst properties for a long time.
