H2 Production
In our group membrane based elctrolyzers are developed for the production of H2 using novel processes like the hybrid sulphur (HyS) process where the hydrogen is produced by the oxidation of SO2 in the presence of water forming H2SO4. Both new and existing membranes are screened for their suitability for this process in terms of…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/process-intensification
Process Intensification
Based on past experience on in-house manufactured zeolite coated ceramic membranes, current research is continuing on the use of zeolites and zeolitic membranes combining their catalytic properties as well as their ability to act as molecular sieves. /sites/natural-sciences.nwu.ac.za/files/files/CRB/imagesSintering…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/gas-separation
