ABOUT ME
I graduated in Chemical Engineering by the University of Zaragoza in 2023. Nowadays I’m studying a Master’s Degree in Chemical Engineering in Zaragoza.
I am a novice investigator in the Catalysis and Reactors Engineering Group (CREG) in the University of Zaragoza, focusing on the CO2 hydrogenation regarding my TFG titled Biogas upgrading through CO2 methanation in a polytropic-distributed feed fixed bed reactor.
