Methanation is a way to further upgrade syngas to a fuel (by converting the CO2 and H2 into a more practical fuel that is CH4). Experiments has been carried out assuming a H2+CO2 mixture feeding the methanation unit as a possible syngas (eventually cleaned and corrected) coming from biomass gasification.
The aim of the study was to study the performance of the perovskite type catalyst for the methanation of CO2. The catalyst was characterized via XRD, BET specific area and SEM analysis in Bilecik Seyh Edebali University Central Lab. After arriving at Polito, in order to reduce the particle size of the catalyst to prevent intraparticle diffusion, the catalyst was pressed into pellet and then crushed and sieved between 0.1-0.3 μm. Catalyst was then ready to activation at 500°C for 2 h under H2 flow before reaction. As final step, the catalytic performance of LaNiO3 was investigated under the discussed conditions.
The study was beneficial to understand the system that was set up in Politecnico di Torino. The effect of reaction variables like temperature, inlet gas composition and volume flow on the conversion was investigated. The BRISKII was a very well opportunity to bind a gap between CO2 methanation to biomass. Within BRISKII framework, it is possible to understand that biomass conversion processes generate CO2 and they are attractive carbon sources due to the biogenic origin and since some of the conversion processes generate gaseous streams with high CO2 concentration.
A catalyst with high CO2 methanation activity at even low temperature is proposed to design within the project scope. According to this, it can be concluded that the study showed the ability to utilize perovskite type catalysts in Sabatier reaction.
The BRISKII provided a good opportunity to make collaboration between Bilecik Seyh Edebali University and Politecnico di Torino. The project leads the researchers coming from different disciplines including chemical engineering and energy departments worked fruitfully together.
