Real-time monitoring of catalytic surfaces using a mass/heat flow sensor: Hydrogenation of ethylene on platinum and palladium

Smith AL, Shirazi HM, Smith FC

A quartz crystal microbalance/heat conduction calorimeter has been used to monitor simultaneously the heat of reaction and the change in surface mass when H-2 and C2H4 in a N-2 carrier react on palladium and on platinum surfaces at temperatures of 25-50 degrees C. The measured turnover rate of the H-2 + C2H4 reaction on platinum at 50 degrees C is consistent with literature values.
