Introduction: The CEL-GPPCM micro-photothermal catalytic micro-reactor system is suitable for the evaluation and screening of photo-thermal synergistic catalysis and photocatalytic catalysts, and can be used for the research of photocatalytic reaction kinetics and reaction process. Mainly used in high-temperature photothermal catalytic reactions, photothermal synergistic catalysis, and can be specifically used for the synthesis and sintering of semiconductor materials, the preparation of catalyst materials, the activity evaluation of catalyst materials, the photolysis of water to produce hydrogen, the photolysis of water to produce oxygen, the reduction of carbon dioxide, and the gas phase Photocatalysis, photocatalytic degradation of formaldehyde gas, VOCs, NOx, SOx, nitrogen fixation and other fields. The system adopts a quartz reactor, which can meet the requirements of light transmission and can carry out high-temperature experiments. The system uses a heating furnace to heat the reactor, which can ensure the stability of the temperature during the reaction process. The system is designed with three gas paths for feeding, equipped with 1 path of gas purge, and 1 path of liquid path interface is reserved at the same time (the required liquid raw materials can be added quantitatively). The system includes: feed steady flow system, reaction constant temperature system, product collection system, control system The cabinet of the system is made of aluminum profile, with matching bolts and nut fixing parts, which is beautiful and easy to maintain and disassemble. The connection with the pipeline adopts a double ferrule joint, and the high-pressure experiment and conventional thermal catalytic reaction can be done by replacing the reactor.

Control system: The system adopts the control module and the touch screen computer (included) for joint control. On the touch screen computer, 100% instrument function operations can be realized, such as real-time reading of measured values, given values, setting parameters, automatic/manual switching, and starting/stopping programs. , And have data storage and export functions. 5. Process monitoring and control: control and display the temperature and gas flow of the reactor. Realize the monitoring of pressure and reactor bed temperature during the reaction. 6. Realize over-limit alarm and interlock safety protection for temperature and pressure. The temperature is two-level alarm. When the temperature is higher than the first set value, it will alarm by sound and light. When the temperature is higher than the second set value, it will automatically stop heating; when the pressure is higher than the first set value, it will alarm by sound and light, which is higher than the second set value. Stop feeding when the value is reached. 7. On-site display: There is a fine pressure gauge at the entrance of the reactor, which is used to display the current reaction pressure of the reactor in real time, and it is matched with the digital display pressure sensor control screen. 8. Control interface: The control interface has a control flow chart with control points, a parameter setting table, a temperature program setting, an alarm window, historical data, and the real-time curve and historical curve of each control point. The historical curve retains time forever.
