Abstract

In this study the performance of two different Ni-based oxygen carriers in a 120kW chem. looping pilot rig at Vienna University of Technol. is presented. A dual circulating fluidized bed (DCFB) system has been designed with the important characteristics of high solid circulation, very low residence times and a high power to solid inventory ratio. For all presented results the pilot rig is fueled with methane at 140kW fuel power. For both oxygen carriers high CH4 conversion and CO2 yield is achieved. Air to fuel ratio and temp. are varied. CH4 conversion at higher air to fuel ratio as well as at higher temp. seems to decrease. This phenomenon is linked to the Ni/NiO ratio of the particle which dets. the catalytic activity and thus influences the CH4 conversion and the CO2 yield. [on SciFinder(R)]
