On the Application of an In Situ Catalyst Characterization System (ICCS) and a Mass Spectrometer Detector as Powerful Techniques for the Characterization of Catalysts

The in situ characterization of catalysts provides important information on the catalyst and understanding its catalytic performance selectivity for a specific reaction. Temperature programmed analyses (TPX) techniques reveal role support stabilization dispersion active sites. However, these can be altered at high temperatures since sintering species occur as well possible carbon deposition which hinders deactivates catalyst. spent catalyst, however, may expose causes deactivation. For example, simple temperature oxidation (TPO) analysis produce CO CO2 via reaction with O2 this is strong indication that deactivation due to carbon. Other TPX such reduction (TPR) pulse chemisorption are also valuable when they applied fresh then upon In work, two Ni supported were considered examples elucidate importance study hydrogenation CO2.
