H2 Production
Jan 19, 2017 - 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…https://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/process-intensification
Process Intensification
Jan 19, 2017 - 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 ovens for…https://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/gas-separation
Gas Separation
Jan 19, 2017 - While gas permeation studies form an intrinsic characterisation tool both for the inorganic as well as organic membranes for various applications, there are ongoing projects focussing specifically on the resolution of various perfluorinated compounds. These projects focus mainly on finding membrane based separation processes to replace…https://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background
Background: Membrane Technology
Aug 30, 2017 - Key Research Areas Research Focus The aim of our research group is to find novel, cost effective and environmentally friendly membrane based separation solutions for industrial as well as rural applications with a specific emphasis on South African relevance. There are two cross-linked key areas of interest within our research group…https://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/postgraduate-students
