-
(University of Pretoria, 2017)To assess the performance and future possibilities of catalytic microwave pyrolysis, laboratory-scale experiments were conducted on a widely available biomass feedstock, Eucalyptus grandis. Non-catalysed microwave pyrolysis ...
-
(University of Pretoria, 2013-01-07)The pyrolysis of biomass is a thermochemical process in which woody biomass is converted to several high-value products such as bio-oil, bio-char and syngas. The forestry sector has shown particular interest in this process ...
-
(University of Pretoria, 2008-09-09)Residence time distributions have become an important analytical tool in the analysis of many types of flow systems. Residence time distributions have proven to be effective for analysing trickle bed reactors, as it allows ...
-
(University of Pretoria, 2015)The Combustion Reduction Integrated Pyrolysis System (CRIPS) is a dual fluidised bed fast pyrolyser that was developed at the University of Pretoria for the conversion of biomass waste to biofuels. The dual fluidised bed ...
-
(University of Pretoria, 2015)Thermal drying of a pulp sheet on a paper machine is one of the most energy-intensive operations in the paper-making process (Ghosh, 2011). The drying section of a paper machine removes less than 20% of the total water ...
-
Fast and microwave-induced pyrolysis bio-oil from Eucalyptus grandis : possibilities for upgrading (University of Pretoria, 2015)The hardwood Eucalyptus grandis has been shown to be an important commodity for forestry-related industries as it has significantly faster specific growth rates per annum when compared with other types of tree species. It ...

(University of Pretoria, 2006-12-20)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2015)The present investigation was aimed at studying the hydrodynamic behaviour of fluidization in an unconventional fluidized bed geometry consisting of a vertically orientated annular space. It was hypothesized that by using ...
-
(University of Pretoria, 2005-09-21)The purpose of the investigation was the design and development of an oxygen carrier system for oxygenation of liver cells (hepatocytes) in a bio-artificial liver support system. Acute liver failure is a devastating condition ...
-
(University of Pretoria, 2010)The Council for Scientific and Industrial Research (CSIR) in South Africa is developing a process to produce titanium tetrachloride from a low-grade material such as ilmenite. Titanium tetrachloride can then be used as ...

(University of Pretoria, 2010-09-17)Please read the abstract in the dissertation. Copyright
-
(University of Pretoria, 2015)Pyrolysis of biomass is the thermochemical conversion process whereby the long lignocellulosic polymers in biomass are cracked into several higher-value products such as bio-oil, bio-char and combustible non-condensable ...
-
(University of Pretoria, 2019)Energy systems and products have always focused heavily on the fuel rather than the oxidant. That oxygen is the definitive factor in the exothermicity of combustion reactions rather than the fuel is demonstrated ...
-
(University of Pretoria, 2021)Near-net-shape manufacturing of titanium metal components through powder metallurgy confers various cost-saving benefits, from improved material utilisation to reduced energy consumption. Further savings can be realised ...
-
(University of Pretoria, 2014)The Council for Scientific and Industrial Research (CSIR) is developing a novel process to produce titanium metal at a lower cost than the current Kroll process used commercially. The technology initiated by the CSIR ...
