The CEL-GPPCH photocatalytic micro-reactor is suitable for the evaluation and screening of photothermal synergistic catalysis and photocatalytic catalysts, and can be used for the study of reaction kinetics and reaction history of photocatalysis. Mainly used in high temperature photothermal catalytic reaction, photothermal synergistic catalysis, Specifically, it can be used in the synthesis and sintering of semiconductor materials, preparation of catalyst materials, activity evaluation of catalyst materials, photohydrolysis of water for hydrogen production, photohydrolysis of water for oxygen production, reduction of carbon dioxide, gas phase photocatalysis, photocatalytic degradation of formaldehyde acetaldehyde gas, degradation analysis of benzene series, VOCs, NOx, SOx, nitrogen fixation and other fields.


The plant has two sets of reactors: kettle reactor and tube reactor. Realize gas solid liquid multiphase system catalytic reaction, gas solid high temperature catalytic reaction, to meet the evaluation needs of most catalysts.


The standard tubular quartz reactor can meet the requirement of light transmission and can be used for photothermal catalysis experiments at high temperature. Using a heating furnace to heat the reactor can ensure the stability of temperature in the reaction process. At the same time, two sets of metal tube reactor are used as spare parts, and the connection with the pipeline is made of double clamping sleeve joints. The metal tube reactor can be used for high pressure experiment and conventional thermal catalysis experiment.


Cauldron reactor with flange seal, the top of the window structure, can meet the need of illumination in the process of experiment; If the lens adopts high-strength sapphire lens, it can also meet the high pressure reaction in the process of the experiment (the temperature can be controlled from normal temperature to 200℃), and the highest pressure can reach 5MPa.


This device is standard equipped with 3 gas channels (can be expanded to 5 channels) feeding, a liquid feeding (metering pump optional). The system includes: feed steady flow system, reaction constant temperature system, product collection system, control system.


The cabinet body of the device is made of aluminum profiles, and the supporting bolts and nuts are used to fix the parts, which are beautiful and easy to maintain and disassemble.

5. Control system: the system adopts the control module and the touch screen computer for joint control. On the touch screen computer, it can read the measured values, set values, set parameters, automatically/manually switch, start running/stop programs, and have the functions of data storage and export.

6. Process monitoring and control: control and display the temperature and gas flow of the reactor. The pressure and temperature of the reactor bed can be monitored during the reaction.

7. Realize the off-limit alarm and interlocking safety protection for temperature and pressure. The temperature is a two-stage alarm. When the temperature is higher than the first set value, the acousto-optic alarm is given. When the temperature is higher than the second set value, the heating will stop automatically. When the pressure is higher than the first set value, the sound and light alarm; when the pressure is higher than the second set value, the feeding is stopped.

8. Field display: there is a fine pressure gauge at the inlet of the reactor, which is used to display the reaction pressure of the current reactor in real time, and matched with the digital display pressure sensor control screen display.

9. Control interface: the control interface has control flow chart with control points, parameter setting table, program temperature setting, alarm window, historical data, real-time curve and historical curve of each control point, and the historical curve retains a permanent time.
