Catalytic reaction of gases

In technical processes there are many gas streams like product gases, intermediate gases (syngas, nitrogen oxides, hydrocarbons, biogas, wood gas) as well as VOC-containing waste gases (VOC - Volatile Organic Compound). Often heterogeneous catalyzed reac-tions are used for a further processing of these gases mainly based on fine dispersed novel metals in form of coatings on a ceramic substrate.
Ceramic catalysts are an interesting alternative because their activity and selectivity de-pend strongly on the chemical composition and can be easily adapted. In addition ce-ramic catalysts are cheaper compared to noble metal catalysts. Therefore not only coat-ings but also bulk materials can be used which can be simple manufactured. On this way the yield can be increased or the residence time can be minimized. In addition ce-ramic catalysts are much more stable against catalyst poisoning.
