Infrared Diffuse Reflectance System
Product introduction
Infrared reaction system is a device that uses Fourier transform infrared spectrometer to evaluate the performance of catalyst or material under multiple environments, and an instrument that evaluates the performance of catalyst/material under various conditions. It can easily track and identify the intermediate states and products of the reaction, thus providing direct evidence for the investigation of the reaction mechanism of the catalytic reaction system. Infrared diffuse reflectance is mainly used for the characterization of gas-solid catalysis and the study of catalytic reactions, such as the identification of oxhydryl on the catalyst surface, the study of species adsorption on the catalyst surface, and the characterization of acid-base on the catalyst surface. The reaction system can be applied to vacuum to high pressure environment, and the temperature is up to 500℃(under vacuum). It is an ideal choice for studying heterogeneous catalysis, gas-solid interaction, photochemical reaction and oxidation mechanism. At present, it has been applied to the infrared spectrum study of gas-solid interface reaction in the fields of photocatalytic degradation of gas-phase organics, thermal catalysis (CO+H₂, CO₂+H₂), etc.
Product parameters
●The tank body is mainly made of 316L stainless steel,with maximum temperature resistance of 500 ℃ and pressure resistance of 3MPa;
●The reaction tank can be equipped with a high-precision touch screen temperature controller for precise temperature control and heating, and the cooling circulation device is used to cool the outside of the reaction tank;
●The reaction cell cavity cap has three windows, two of which are infrared windows and the other one is quartz windows, which are used to introduce external light sources (photocatalytic excitation light sources) or as observation windows;
●Three inlets/outlets are provided for emptying the tank and introducing gas. Reaction gases such as VOCs and CO ₂ can be formed in the reaction tank.The reaction tail gas is first introduced into the safety bottle, then absorbed by the specific solution, and then discharged to the outside. Each gas flow is controlled by a mass flowmeter. The operation interface of reaction gas circuit is convenient, friendly and easy to operate.
●Various optical windows can be customized,and high-temperature Raman cell is optional.
