dc.description.abstractThe purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications. Blueprints for the designed parts were developed and sent to Mekpart AB in M olndal for manufacturing. Remaining components were either ordered from different companies or manufactured by hand. After delivery the device was tested with an amount of 10 g ilmenite and an airow of 15 L/min. The attrition-rate was measured by plotting the weight of fines collected against time.The time-dependence of the particle attrition rate adopted a linear appearance after a short time. When the test was repeated the reproducibility was proven to be good. However the device was not able to be tested for a 20 L/min airow because the pressure drop became higher than calculated and the relief valve mounted in the humidity deviceopened.
