STUDENT DETAILS

Faan du Preez (GRADUATED)

PhD Chemistry

Faan grew up on a farm in Roodekopjes, Brits. He matriculated from Wagpos High School in 2007. He then enrolled at the North-West University (Potchefstroom Campus) where he completed his higher education. His post graduate studies focused on environmental, waste management, and process related aspects of the ferrochromium industry; with main focus on lowering specific electrical consumption of smelters, carbon footprint reduction, rehabilitation of hazardous process residues, and recovery of valuable from process residue streams, as well as hydrogen generation by the reaction of mechanochemically activated aluminum and water.

Project

Catalyst development for continuous catalytic hydrogen combustion for safe heat generation applications in rural areas

This project aims toward developing materials for catalytic hydrogen combustion applications.  The use of low cost catalysts supports is evaluated to decrease the overall catalyst cost.  In addition, locally produced Pt is functionalized and used as the reactive metal.  The objective of this study is to develop a device using consumer produced hydrogen as a fuel source for a catalytic hydrogen combustion device for indoors domestic applications such as cooking and spatial heating.  By doing so, the ambient household air-quality will improve significantly, which will likely alleviate health issues relating to poor-air quality exposure/inhalation.  A secondary object is the development of a passive autocatalytic hydrogen recombiner for hydrogen safety applications – usable to mitigate risks associated with hydrogen leakages in confined/poorly ventilated spaces.
