Operating experience with chemical looping combustion in a 120kW dual circulating fluidized bed (DCFB) unitPhilipp Kolbitsch, Tobias Pröll, Johannes Bolhar-Nordenkampf, Hermann Hofbauer In this study, first operating experience with a 120kW chemical looping pilot rig is presented. The dual circulating fluidized bed reactor system and its auxiliary units are discussed. Two different oxygen carries, i.e. ilmenite, which is a natural iron titanium ore and a designed Ni-based particle, are tested in the CLC unit. The pilot rig is fueled with H2, CO and CH4 respectively at a fuel power of 65-145kW. High solids circulation, very low solids residence time and low solids inventory are observed during operation. Due to the scalability of the design concept, these characteristics should be quite similar to those of commercial CLC power plants. Ilmenite shows a high potential for the combustion of H2 rich gases (e.g. from coal gasification with steam). The H2 conversion is quite high but there is still a high potential for further improvement. The Ni-based oxygen carrier achieves the thermodynamic maximum H2 and CO conversion and also very high CH4 conversion. A variation of the air/fuel ratio and the reaction temperature indicates that the Ni/NiO ratio of the particle has a high influence on the performance of the chemical looping combustor. © 2008 Elsevier Ltd.

Synthesis gas generation by chemical-looping reforming using a Ni-based oxygen carrierLuis F. de Diego, MarÃa Ortiz, Francisco GarcÃa-Labiano, Juan Adánez, Alberto Abad, and Pilar Gayán This work presents the experimental results obtained during auto-thermal chemical looping reforming (CLR) in a 900 Wth circulating fluidized bed reactor using methane as fuel. An oxygen carrier based on NiO and supported on γ-Al2O3 was used during more than 50 hours of operation and the effect of different operating variables, like fuel reactor temperature, H2O/CH4 molar ratio and solid circulation rate, on CH4 conversion and gas product distribution was analyzed. It was found that in all operating conditions CH4 conversion was very high (>98%) and the most important variable affecting to the gas product distribution was the solid circulation rate, that is, NiO/CH4 molar ratio. During operation the oxygen carrier particles maintained their physical and chemical properties. These results suggest that this oxygen carrier could have a high durability, being a suitable oxygen carrier for a CLR system. © 2008 Elsevier Ltd. All rights reserved.
