Work Package 4 „Catalyst Development “

This work package involves the development of catalysts for fuel reforming and water gas shift reaction. A fuel-flexible, sulphur tolerant and coke resistant reforming catalyst will be developed which is suitable for diesel and biodiesel at the specified operating regime defined in WP1. Additionally, a sulphur tolerant water gas shift catalyst will be developed. For both – reforming and shift catalyst – sufficient durability for inclusion into the integrated system will be demonstrated. Some degree of catalyst deactivation or loss in performance can be anticipated using sulphur and coke precursor containing feedstock and regeneration strategies will be investigated which will allow catalyst activity to be restored in-situ.
