Beschreibung
Zusammenfassung:	The invention discloses an on-line gas-solid kinetic testing method and device. The device comprises a quality gas mixing system and more than one gas cylinder connected to the quality gas mixing system, wherein the quality gas mixing system is connected with a preheating vacuum furnace through a gas inlet valve; the preheating vacuum furnace is connected with a reaction vacuum furnace through a thermal-insulation pipeline and a controllable solenoid valve; the reaction vacuum furnace is connected with the vacuum system through a controllable exhaust valve; a pressure sensor and a temperature sensor are arranged in the reaction vacuum furnace; the controllable solenoid valve, controllable exhaust valve, pressure sensor and temperature sensor are respectively connected with a control system. The method and device can accurately and efficiently test the reacting weight-time relationship curve, reaction fraction-time relationship curve, unit area reacting weight-time relationship and other kinetic test results i
