BSc (2018) and MSc (2020) in Chemical Engineering at University of Zaragoza (Spain), and LUT University (Finland). There, I also prepared my master’s Thesis working for VTT Technical Research Centre of Finland in the Renewable Energy Processes team in issues related to CO₂ adsorption from air. Back in Spain, I was hired as a research engineer in the Thermochemical Processes Group of UNIZAR in the reduction of NO_x emissions from ammonia combustion. Since 2021, I am preparing my PhD Thesis in the field of energy valorization of biogas and renewable hydrogen by intensification with advanced materials and multifunctional reactors in the Catalysis and Reactor Engineering Group (CREG) of UNIZAR. I participated in an international collaboration as visitor researcher in the Large Scale Energy Storage group of TU Delft (The Netherlands).

Currently working in the H4BIOMET project.

abstract = {Carbon dioxide methanation is a promising route for renewable natural gas production, although its performance is often limited by kinetic constraints under severe operating conditions. In this work, distributed reactant feeding in a four-inlet polytropic fixed-bed reactor was investigated as a process intensification strategy for CO2 methanation and biogas upgrading over a conventional methanation catalyst (Ni-Fe). The effects of feeding configuration, GHSV, temperature and feed composition on CO2 conversion and CO selectivity were systematically assessed and compared with conventional co-feeding operation. Distributed CO2 feeding consistently outperformed both conventional and hydrogen-distributed configurations, providing higher CO2 conversions and lower CO selectivities. The beneficial effect was particularly evident at high space velocities and low conversions, where kinetic limitations and selectivity to the unwanted CO are more pronounced, reaching reduction of 50 % in this parameter in the more kinetically-hindered conditions. The same qualitative behaviour was observed when upgrading a synthetic sweetened biogas (70 vol% CH4 and 30 vol% CO2), demonstrating the applicability of the proposed strategy under feed compositions relevant in practice. The improved performance is attributed to the establishment of locally H2-rich environments along the catalytic bed, which promote methane formation and mitigate CO accumulation without modifying the global operating conditions. These results highlight the potential of distributed reactant feeding as an effective reactor engineering approach for enhancing methanation performance and intensifying renewable natural gas production processes.},
