The product is a customized system designed for the fixed-bed photothermal ammonia synthesis applications of Professor Tang's research group at Tsinghua University. This device is a multi-system setup developed to address the construction of laboratory gas-solid phase catalytic reaction evaluation equipment. It is mainly composed of five parts: gas distribution system (including liquid delivery pump), preheating system, light source and reaction system, condensation and gas separation system, and backpressure control system. The control center uses PLC programming with high-definition touch operation control.
Dual-channel photothermal fixed-bed device, allowing simultaneous screening of two catalysts in one experiment;
Top-illumination photothermal design, internal light conduction, low light source loss;
Reactor is easy to disassemble, simple to use, and flexible in operation;
Automatic control of system pressure increase and decrease, automatic liquid sampling control;
PLC programming combined with touch screen for convenient control operation;
No need for multi-channel gas distribution or preheating module design, resulting in a relatively compact device structure.
