Abstract [en]

Natural ilmenite has been proposed as potential low-cost catalyst for biomass gasification due to its mechanical stability and thermochemical properties at high temperature. Previously works demonstrated that ilmenite showed high activity in water-gas shift reactions, but its limited catalytic activity in tar conversion requires improved performance. Therefore, the present work is focused on synthesis of synthetic catalyst based on Fe-Ti-Ni-O system, testing of their catalytic activity, and detailed studies of relevant factors such as structural and microstructural features and redox behavior under gasification conditions. Thermodynamic predictions were performed to assess expected thermochemical conditions required for the synthesis of catalyst, and the corresponding stability windows in prospective catalytic operation. A simple approach based on microwave irradiation was applied in the preparation of the catalyst, revealing a high potential for reducing production costs. Preliminary catalytic testing using model tar compounds demonstrated that the synthesized catalyst shows enhanced performance for conversion of tar impurities through steam reforming reaction.
