Chemical Industry Electrification: Microwave Heated Reactors, Prospects for Efficient Use of Energy
Microwave radiation MW is introduced as a method for intensifying heating in chemical processes. In solid-gas reactions, the selective heating of the solid offers an energy-saving advantage. Additionally, the temperature difference between the solid and the gas can enhance selectivity, providing further benefits. Knowing microwave heating mechanism in catalytic solids is crucial to understand and control the process. In this seminar we will explain about the fundamentals of heating mechanism in solids, the development of an experimental set-up for MW heated chemical reactors and revise the results for several processes.

Reyes Mallada VianaInstituto de Nanociencia y Materiales de Aragón (INMA) CSIC-Universidad de ZaragozaReyes Mallada is a professor of Chemical Engineering at the University of Zaragoza. Her research focuses on the development of materials, primarily micro- and mesoporous materials, metal nanoparticles, and metal nanoparticles supported on porous materials. These materials are used in the fields of membranes, catalysis, adsorption, and sensors. At the same time, these applications seek to achieve process integration, one of the paradigms of chemical engineering in the last decade. This integration is achieved through the combination of reaction and separation in membrane reactors, miniaturisation and an increase in the surface-to-volume ratio in micro-reactors and structured reactors, and the use of alternative forms of energy to activate processes, such as microwaves or light.
She has participated in more than 50 research projects, 12 of them European, and of these, 4 dedicated to the application of microwaves in chemical processes. She has co-supervised 16 doctoral theses and published more than 120 scientific articles, a third of which are dedicated to microwave heating processes. She is executive editor of the journal Chemical Engineering Process and Process Intensification and is currently director of the Department of Chemical Engineering and Environmental Technologies at the University of Zaragoza.
