In recent years perovskite-type membranes (ABO3) have been studied intensively as oxygen permeable materials. These perovskite ceramics very often have a disc or tube geometry. In this paper the first data of a membrane reactor for POM with hollow fi

Perovskite hollow fibre membranes of the composition BaCoxFeyZr1−x−yO3−δ (BCFZ) were prepared by a spinning process and subsequent sintering. The fibres were successfully tested in the production of pure oxygen and oxygen-enriched air as well

For an effective operation of a membrane reactor in comparison with a conventional fixed-bed reactor, the kinetic compatibility of hydrogen production and its removal is essential. The aim of this work is to provide an estimation of the membrane area

A membrane reactor with perovskite hollow fibres in combination with a commercial steam reforming catalyst is used to produce in a long term scale synthesis gas with a methane conversion of about 96%, a CO selectivity of 95% and at a H-2/CO ratio of
