This device combines the two technologies of photothermal and catalysis, and is usually used to achieve chemical reactions, decomposition or conversion at high temperatures. High-temperature photothermal catalytic reaction devices are widely used in many fields, including environmental protection, energy production, chemical synthesis, etc.

The high-temperature photothermal catalytic reaction device is provided with vacuum pump 1 and vacuum pump 2. When conducting a high-temperature photothermal catalytic reaction experiment, vacuum pump 1 is started to extract the air in the outer shell, so that the outer shell is in a vacuum state, the temperature is not easy to lose, and the insulation effect of the reactor is improved. Starting vacuum pump 2 can pressurize or evacuate the interior of the reactor according to demand, thereby improving the experimental efficiency. A cylindrical outer shell is provided with good pressure resistance. The shape of the reactor is a cylinder with arc-shaped upper and lower ends. It has high structural strength, relatively uniform force, and can withstand high-pressure reaction conditions;
