Abstract

By using PSRA (Pulse Surface Reaction Rate Analysis) coupled with EDR (Emissionless Diffuse Reflectance Infrared Spectrometer), it was found that the lower shift of C−O stretching vibration of absorbed CO — caused by the addition of alkali carbonate to Ru/Al2O3 — leads to a decrease in the rate constant for the C−O dond dissociation process of adsorbed CO in methanation.

Abstract

Используя Импульсный Анализ Скоростей Поверхностных Реакций совместно с ИК спектрометрией безэмиссионного диффузного отразения, было найдено, что более низкое смещение валентных колебаний C−O адсорбированной CO — вызванное добавлением щелогного карбоната к Ru/Al2O3 —приводит к уменьшению константы скорости процесса диссоциации связи C−O адсорбированной CO в конверсии окиси углерода в метан.
