Biodiesel production from sunflower oil using microwave assisted transesterification
(North-West University, 2013)
Biofuels are becoming more attractive worldwide because of the high energy
demands and the fossil fuel resources that are being depleted. Biodiesel is one of the most attractive alternative energy sources to ...
Separation of Grubbs-based catalysts with nanofiltration
(North-West University, 2008)
This thesis describes the use of organic solvent nanofiltration (OSN) in the field of metathesis for separating homogeneous Grubbs-type catalysts from their post-reaction mixtures for the model metathesis reaction of ...
Microwave assisted pretreatment of sweet sorghum bagasse for bioethanol production
(North-West University, 2013)
The growing demand for energy in the world, the implications of climate change, the increasing damages to our environment and the diminishing fossil fuel reserves have created the appropriate conditions for renewable energy ...
Extraction of oil from algae for biofuel production by thermochemical liquefaction
(North-West University, 2009)
The extraction of oil from microalgae was investigated. The study focused on the
hydrothermal liquefaction of the microalgae Microcystis aeruginosa, Cyclotella meneghinia and Nitzschia pusilla. M. aeruginosa was ...
Membrane gas separation of Fischer-Tropsch gases
(North-West University, 2005)
Membrane-based gas separation has attracted considerable interest over the past few years because of its low energy consumption and cost-effective separation. Many studies have been conducted related to amorphous silica ...
Fermentation coupled with pervaporation : a kinetic study
(North-West University, 2011)
Ethanol production through biomass fermentation is one of the major technologies available to produce liquid fuel from renewable energy sources. A major problem associated with the production of ethanol through fermentation ...
Liquefaction of sunflower husks for biochar production
(2014)
Biochar, a carbon-rich and a potential solid biofuel, is produced during the liquefaction of biomass. Biochar can be combusted for heat and power, gasified, activated for adsorption applications, or applied to soils as a ...
Preparation of polyurethane foam from lignin and crude glycerol
(North-West University (South Africa), Potchefstroom Campus, 2018)
The development and implementation of lignocellulose-based biorefineries which produce renewable fuels, chemicals and pharmaceuticals are expected to grow, but still face technological challenges. Economic feasibility could ...
Continuous microwave-assisted biodiesel production
(North-West University (South Africa) , Potchefstroom Campus, 2016)
The impetus of this study focuses on the production of fuel-substitute i.e. biofuels. This arises from its similar properties with petroleum diesel and being environmentally benign. In particular, biodiesel is defined as ...
Effect of operating parameters on bio-products obtained from the liquefaction of Quinoa lignocellulose materials
(North-West University (South Africa) , Potchefstroom Campus, 2017)
An increased reliance on energy production and the consumption thereof is the result of an exponentially growing world population. Current global energy resources rely greatly on coal, natural gas and to a small extent on ...
