(University of Pretoria, 2012)A selective combination of the principles of a thermal mass flow meter and constant temperature anemometry was used to develop a solid mass flow meter that improves significantly on the flow meter developed by De Vos et ...
-
(University of Pretoria, 2008-09-09)The entrainment rate of Ferrosilicone (FeSi) particles was measured in a 140 mm perspex column with air as the fluidising medium. Two different types of FeSi were used, namely atomised FeSi, which is mostly spherical in ...

(University of Pretoria, 2007-05-15)Reaction rate data at 50oC was generated in a batch reactor over a wide range of initial concentrations in the reaction mixture. In each case the reaction was allowed to reach equilibrium. Equilibrium conversion data clearly ...

(University of Pretoria, 2012-06-29)Solid phosphoric acid is a catalyst used for the upgrading of light olefins into fuels. To delve into the mechanism of olefin dimerisation over the catalyst, the oligomerisation of 1- hexene was investigated over a wide ...
-
(University of Pretoria, 2020)This project deals with the mixed micellar and interfacial properties of mixtures of three surfactants [sodium dodecyl sulphate (SDS), cetyltrimethylammonium bromide (CTAB), and tetraethylene glycol monododecyl ether ...
-
(University of Pretoria, 2008-07-10)The existence of multiple hydrodynamic states (MHS) in trickle bed operation has been proved by hysteresis observed in flow loops, as well as variation between different prewetting modes. The most common theory presented ...
