Hardware system control:
1. Analysis pressure: atmospheric pressure
2. Programmed heating electric furnace: a closed heating furnace with a room temperature of -1200 ℃, and a safety insulation cover on the furnace wall to prevent burns (low-temperature reaction furnace can be selected at -120 ℃ -1200 ℃);
3. Reactor: High temperature resistant U-shaped quartz reactor with an upper temperature limit of 1200 ℃, which can fully preheat the reaction gas and accurately obtain the bed temperature and temperature inside the reaction furnace, improving temperature control accuracy; The reactor is designed with an overflow channel to block the gas path polluted by the removed substances
4. Signal detector: Original four-wall PT gold-plated TCD detector with strong antioxidant and ammonia corrosion resistance, stable current control ensures baseline stability and test reproducibility signal
5. Temperature detection: The thermocouple is embedded in a U-shaped bypass reactor, which can accurately capture the temperature of the catalyst bed layer
6. Steam generator: The operating temperature is -25 ℃~300 ℃ (the upper temperature limit can be set to prevent overheating)
7. Flow control: Multiple sets of high-precision digital mass flow controllers, parallel gas path structure (based on detectors), supporting customized use of different range flow controllers. In addition to high-purity gas, gas conversion coefficients can also be set for different concentrations of mixed gas, achieving precise control
8. Air circuit system:
Control: Electric six way valve and solenoid valve control module, equipped with visual software control interface, real-time display of gas circuit status
Structure: Set up multiple bypasses and intelligently switch according to experimental steps
9. Constant temperature system: adjustable electric furnace+through type strong air cooling system, which can quickly achieve high temperature to room temperature cooling, with a cooling time of less than 25 minutes
