Engineering Research Equipment: A Diffuse Reflectance Fourier Transform Infrared Spectroscopy System

在操作条件下，粉末催化剂上吸附物质的表征系统正在组装中。组件包括傅里叶变换红外（FTIR）光谱仪，漫反射（DRIFTS）附件，质量流量控制器和温度控制器。该设备将用于若干研究，重点是减少固定电源的氮氧化物排放。这些研究包括在锰氧化物上分解一氧化氮和二氧化氮，用甲烷在镧或掺杂氧化镁上还原一氧化氮，以及用吸附的一氧化碳表征碳负载钯

A system for the characterization of adsorbed species on powder catalysts under operating conditions is being assembled. Components include a Fourier-transform infrared (FTIR) spectrometer, a diffuse reflectance (DRIFTS) attachment, mass flow controllers, and a temperature controller. This equipment will be used in several studies, with emphasis on abatement of nitrogen oxide emissions from stationary power sources. The studies include decomposition of nitric oxide and nitrogen dioxide on manganese oxides, reduction of nitric oxide by methane ovre lanthana or doped magnesia, and characterization of carbon-supported palladium using adsorbed carbon monoxide.//
