Javier Herguido

Javier Herguido is Professor of Chemical Engineering (Catedrático de Universidad) at the School of Engineering and Architecture (EINA) of the University of Zaragoza (Unizar), since 2007. He holds a B.Sc. and M.Sc. in industrial chemistry (1987) and a PhD in Science – Chemical Engineering program (1991). In 1993 holder of the chair ‘Chaire Hélioparc’ at the Technology Center ‘Hélioparc Pau-Pyrénées’ (France). Guest professor at several research centers and universities: ‘Laboratoire de Physico-Chimie Moléculaire’ CNRS-France, PUCP University-Peru, National University of Cuenca-Ecuador.

He was the Head (Director) of the Department of Chemical Engineering and Environmental Technologies – Unizar (July 2016-December 2024), and currently he is the Secretary of the Spanish Catalysis Society (SECAT) governing board.

Regarding his research activity, he is a member of the Aragon Institute for Engineering Research (I3A- http://i3a.unizar.es/) where he leads the Catalysis and Reactor Engineering research Group (CREG-https://creg.i3a.es/). His current research activity focuses on the area of Chemical Reactor Engineering including:

a) Hydrogen and CCU technologies: his current research efforts are devoted to fields related with hydrogen production and/or purification from several sources, hydrogen utilization in Power to Gas processes such as CO₂ methanation, and Power to Liquid processes (methanol, DME, olefines, gasolines, syngas … production), and e-fuels production enhancement.

b) Processes intensification, including the use of multifunctional reactors.

c) Non-conventional fluidized-bed reactors (e.g., with separation of oxidizing and reducing zones, with segregation of solids, etc.) for the intensification of catalytic processes.

He has participated in 46 research projects, largely as main investigator. His scientific production includes: 136 papers (counting several reviews per invitation) in JCR-indexed journals such as AIChEJ, Appl. Catal., Cat. Today, CEJ., CES, IECR, Int. J. Hydrogen Energy, J. Catal., J. Power Sources, Powder Tech., Studies Surf. Sci. Catal., Prog. Energ. Combust. (PECS), among others; over 430 presentations at scientific meetings; 3 patents; and the book “Chemical Reaction Engineering” (1999, Ed. Síntesis, Madrid). He has supervised 14 PhD thesis. He has the Extraordinary Doctorate Award and the 3M-Foundation Prize for Innovation – 2004 (environment category). Member of organizing/scientific committees of many national and international congresses. He also acts as reviewer for several international organizations (ANEP-Spain, ANPCyT-Argentina, PUCP-Perú, SENACYT-Ecuador, …) and 21 international journals.

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.},
