摘要: A fully automated, versatile Temperature Programmed Desorption (TDP), Reaction (TPR) and Evolved Gas Analysis (EGA) system has been designed fabricated. The consists of a micro-reactor which can be evacuated to 10−6 torr heated from 30 750°C at rate 5 30°C per minute. gas evolved the reactor is analysed by quadrupole mass spectrometer (1–300 amu). Data on each scans temperature given time are acquired PC/AT generate thermograms. functioning exemplified programmed desorption (TPD) oxygen YBa2Cu3−xCoxO7 ± δ, catalytic ammonia oxidation NO over YBa2Cu3O7−δ anaerobic methanol CO2, CO H2O (Y123) PrBa2Cu3O7−δ (Pr123) systems.
