Introduction: PLR-PTSRⅢ photothermal catalytic reaction system (atmospheric pressure), the photothermal fixed bed reactor is a set of catalyst evaluation system for photothermal catalytic reaction, which consists of a light source and a transparent reactor, the light source is independently placed outside the transparent reactor , in order to realize the optical coupling gas-solid reaction process, in the catalytic reaction process, use the temperature controller to control the reaction temperature, and take samples through the six-port valve/ten-port valve (optional), and send the reaction product to the analytical instrument (for example: chromatograph, mass spectrometer gas analyzer, etc.) for online analysis. Therefore, the device can be used to study the reaction performance of photocatalysts such as conversion rate, product selectivity, and catalyst life. Application field: high temperature and atmospheric pressure photoelectric catalysis (such as: CO2 reduction, degradation of VOCs, nitrogen fixation, sulfur fixation, etc.) Features: 1. Mass flow meter controls gas flow rate; 2. The high-efficiency vaporizer fully vaporizes the liquid reactant to ensure full contact and reaction with the catalyst; 3. The light source can be moved horizontally, and the illumination distance of the light source can be adjusted flexibly; 4. The quartz reaction tube is sealed with a rubber ferrule, which is anti-fragmentation and easy to disassemble; 5. Optional chromatograph, mass spectrometer, flue gas analyzer and other analytical instruments can be used to analyze reaction products.
