Reduction Kinetics of Cu-Based Oxygen Carriers for Chemical Looping Air Separation

14-Aug-2013 | Kun Wang; Qingbo Yu; Qin Qin, Energy & Fuels, 2013

The knowledge of the kinetics of oxygen carriers is essential for the design of chemical looping air separation (CLAS) system. In this paper, the Cu-based oxygen carriers were prepared via a mechanical mixing method, and ZrO2, TiO2, and SiO2 were used as binder. The kinetics of the oxygen ...

Application of a Simultaneous TGA-DSC Thermal Analysis System for High-Throughput Screening of Catalytic Activity

01-Nov-2012 | Jonas Loskyll; Wilhelm F. Maier; Klaus Stoewe, Journal of Combinatorial Chemistry, 2012

We present here the use of a simultaneous TGA/DSC thermal analyzer as a high-throughput reactor system to measure after calibration the heat of reaction and therefore the catalytic activity of heterogeneous catalysts in a fast, reliable and reproducible manner. By coupling the gas outlet of the ...
