Problems solved by technology

In order to avoid the influence of component signals in the gas phase, infrared spectroscopy experiments generally need to be carried out under vacuum conditions, and the study of gas flow systems cannot be carried out. However, most of the actual gas-solid catalytic reaction systems use flow systems, so many infrared spectroscopy cells are not In-situ spectroscopic cells in a substantial sense cannot simultaneously study the changes of gas phase components and the ads...

Abstract

The invention relates to an in-situ dual infrared spectrum pool, which comprises a pool body, wherein a cover is respectively arranged on two ports of the pool body; each cover and the port are sealed by a seal ring; an infrared window is arranged on each cover; the lateral wall of the pool body is provided with two holes; a heating tape is coiled on the outer wall of the pool body; a cooling water system is respectively arranged on outer walls of two ends of the pool body; a sample bracket is fixed in the pool body; two sample cells are arranged on the sample bracket; and a thermocouple passes through the wall of the pool body and is in contact with the sample bracket. The in-situ dual infrared spectrum pool disclosed by the invention is suitable for monitoring adsorption of gases at high temperature and different pressures on the surface of a solid material, or reaction or phase change of the solid material per se.

Description

technical field [0001] The invention relates to an in-situ infrared spectrum measuring device, in particular to an in-situ infrared spectrum pool. Background technique [0002] In-situ infrared spectroscopy is an important analytical tool for studying the reaction and phase transition of solid materials themselves, as well as the interaction between gases and solid materials. The in-situ infrared spectroscopy cell is an essential device for in-situ infrared spectroscopy characterization. In order to avoid the influence of component signals in the gas phase, infrared spectroscopy experiments generally need to be carried out under vacuum conditions, and the study of gas flow systems cannot be carried out. However, most of the actual gas-solid catalytic reaction systems use flow systems, so many infrared spectroscopy cells are not In-situ spectroscopic cells in a substantial sense cannot simultaneously study the changes of gas phase components and the adsorption, desorption and...
