Embodiment 1
[0044] The Huolinhe coal is crushed and dried into pulverized coal with a diameter of less than 0.5mm. After drying at 120°C, 50 mg of the pulverized coal sample is placed on a metal platinum sheet, and the micro thermal conversion reactor is closed; quadrupole-time-of-flight mass spectrometry analysis The instrument (MicroTOF-QII, Bruker, Germany) is turned on and in a stable state, and is analyzed in full scan mode. The mass spectrometer can complete 20 full scans per second, and the mass spectrum mass range is set here to be 50-2000; the He carrier gas is turned on And set the carrier gas flow rate to 10L / min, do not open the split port; turn on the independent ion source (Dart-SVP, American Ironsense Company); after 30 minutes of stabilization, turn on the high-speed camera (VW-6000, Japan Keyence Company) and adjust the focus to The clearest picture; heat the metal platinum sheet with electricity, set the heating rate at 6000°C / min, heat it up to 800°C and keep it warm for...
Embodiment 2
[0046] The straw is crushed and dried into a powder with a diameter of less than 1mm, and after being heated to 120°C for drying, 40 mg of the powder sample is placed in a quartz boat wrapped around a platinum wire, and the micro thermal conversion reactor is closed; the quadrupole-time-of-flight mass spectrometer (MicroTOF-QII, Bruker, Germany) is turned on and in a stable state, and is analyzed in full scan mode. The mass spectrometer can complete 20 full scans per second. Here, the mass spectrometer mass range is set to 50-1500; the He carrier gas is turned on and set The carrier gas flow rate is 20L / min, and the split flow rate is 5L / min; turn on the independent ion source (Dart-SVP, Ironsense, USA); after 30 minutes of stabilization, turn on the high-speed camera (VW-6000, Keyence, Japan) and adjust the focus to the clearest image ; Turn on the electricity to heat the platinum wire, set the heating rate to 30°C / min, and raise the temperature to 800°C. The high-temperature ...
Embodiment 3
[0048] Cut waste plastic bags into 2-5mm pieces 2 Take 5 mg of the sample and place it on a metal platinum sheet, and close the miniature thermal conversion reactor; the quadrupole-time-of-flight mass spectrometer (MicroTOF-QII, Bruker, Germany) is in a power-on and stable state, and is analyzed in full-scan mode , the mass spectrometer can complete 20 full scans per second, here set the mass spectrometer mass range 50-2500; turn on the N2 carrier gas and set the carrier gas flow rate to 30L / min, the split flow rate to 25L / min; turn on the independent ion source (Dart-SVP , Ironsense, USA); after stabilizing for 30 minutes, turn on the high-speed camera (VW-6000, Keyence Company, Japan) and adjust the focus to the clearest picture; turn on the electricity to heat the metal platinum sheet, set the heating rate to 300°C / min, and raise the temperature to 1000°C. The high-temperature gas phase components obtained by pyrolysis enter the mass spectrometer under the carrier gas for r...
