Introduction to device structure

1. The device is composed of four parts: gas-liquid feeding system, reaction system, material collection and sampling system, instrument-computer linkage control system;

2. All parts of the device are modular design. In addition to the panel installation of the gas feeding and control cabinet, the rest are framed installation, which ensures the minimum dead volume and the convenience of installation, operation and maintenance of the equipment.

3. The main body of the reactor is made of 316 stainless steel. In order to ensure the temperature consistency after replacing the reactor with different diameters, the reactor is equipped with a temperature uniform sleeve with different inner diameters. At the same time, in order to prevent the liquid material from condensation again, the buffer tank is installed separately in the reactor heating furnace, and the buffer tank is heated separately, and the distance between the buffer tank outlet and the reactor inlet is reduced as far as possible. Reactor structure for removable disassembly.

4. The product is separated once in the high temperature and high pressure gas-liquid separation tank. After the gas phase reduces the pressure to close to normal pressure through the back pressure valve, it can be emptied after sampling through the six-way valve, or stored in the low-temperature sampling tank after condensation.

5. The liquid product is automatically discharged into the sampling tank after the liquid level of the high temperature and high pressure gas-liquid separation tank is controlled by the differential pressure transmitter and pneumatic control valve. The liquid phase can be emptied after sampling through the six-way valve or directly emptied;

6. Equipment accessories and instruments are all selected from well-known manufacturers, and other non-standard devices are designed and processed in a unified way.

2) Reaction and carburetor temperature: room temperature ~ 600℃; Buffer chamber temperature: room temperature ~ 400℃; Temperature of thermostat: room temperature ~ 250℃; Temperature control accuracy: ±1℃.

3) metering pump, liquid flow 0.01-10ml /min; Control accuracy: ±1%FS.

4) High temperature gas-liquid separator liquid level control and do not drop the pressure to take liquid; High temperature sampling valve and valve box with heated air mixing; With six - way valve sampling, sample sampling insulation channel.

5) Independent condenser refrigeration system (room temperature ~ -15℃)

6) The system has two-stage stable pressure and back pressure; It has job security and safety protection system.

7) Analysis system (gas chromatography or mass spectrometer and workstation); (Optional configuration).
