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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Production of ethanol from tropical sugar beet
(North-West University, 2010)
The concern over depleting fossil fuel resources and increasing greenhouse gas emissions has prompted the research into alternative and renewable energy resources. Bioethanol is seen as a potential alternative to petroleum ...
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 ...
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 ...
In-situ biodiesel production using liquefaction and supercritical extraction
(North-West University (South Africa), 2016)
Biodiesel is an alternative source of energy with the potential to replace diesel fossil fuel. Full scale production however, has been hampered by high production costs since the extraction of oil causes excessive losses ...
