Abstract:
In theory, catalytic reforming of tar compounds in product gases derived from gasification of biomass has several advantages compared to other methods and a lot of research has been done within the last years. Yet, there are still a lot of problems regarding the practical application of catalysts in large scale applications. In our project, several different commercially-available and recently-developed catalysts were tested for the reforming of model tar compounds and methane in a simulated producer gas from allothermal biomass gasification in a laboratory scale test rig. Continuing the first tests without poisoning substances, we added H2S to our gas matrix to get a hold on one of the most severe challenges for catalysts. We could perform several comparative tests to assess the performance of Nickel and precious metal catalysts, in monolithic and also bulk type. Down to 800 °C it is possible to convert a considerable amount of tar components even with high tar load. Deactivation seems to be reversible for precious metal and for nickel catalysts too. In a final project step, a development towards the application in large scale systems is done.
