Optimized and scalable COreduction by tuning reaction environment and transport properties

Prof.dr. G. Mul, University of Twente

Projectnumber P17-08 project 1

This project focuses on fundamental understanding and practical optimization of electro-conversion processes in gas diffusion cells. It takes cathodic CO2 reduction to ethylene or Syngas (mixture of CO and H2), and the concomitant, anodic oxidation of sulphide as reactions to demonstrate the functionality of computational models we derive to describe the relevant transport phenomena. At the same time, a lab-demonstrator will be constructed to demonstrate the practical feasibility of electrochemical conversion of industrial waste gasses containing these components. The computational models of the transport phenomena at all relevant length scales will also serve as input for the device designs of projects 2-5.
