Description
technical field [0001] The invention belongs to the technical field of gas utilization, and relates to an ultra-low concentration gas reaction kinetic parameter test system and method in an inert channel. Background technique [0002] Methane is second only to carbon dioxide as a greenhouse gas, and its greenhouse effect is 20 times that of the same concentration of carbon dioxide. Emission of a large amount of methane into the atmosphere is also a waste of energy resources. However, the concentration of exhaust gas is low (usually less than 1%) and unstable, so it cannot be burned in conventional ways. The use of this low-grade energy has become a challenge for the whole world. [0003] At present, systems commonly used in exhaust gas, such as gas thermal storage and oxidation devices, provide a heat storage layer with an operating temperature exceeding 800°C (beyond the ignition temperature of methane). Because the self-heat balance of methane reaction in regenerative ox...
