I read a paper (Journal of Catalysis 287 (2012) 149–160), which reported "initial H2 consumption rate" calculated from H2-TPR profiles. However, I could not understand the derivation process. Can anyone explain how to do it?
In the paper you mentioned, 5%H2-95%Ar gas was used as a carrier gas for carrying out TPR studies. They carried out the TPR study from RT to 900 C. While increasing the temperature, at a certain tempearature the oxide form of metal will consume H2 to reduce it to metal form and release one molecule of water. Water will be trapped in a Moisture trap and the gas will be flown to a TCD detector. Based on the detector response (Integrated area of the curve), using the pre-calibration values, the amount of H2 consumed will be calculated.
In the paper, they referred two zones, one is below 500C and another is above 500C.
