A South African perspective investigatingfive nitrogen application levels for optimumsweet sorghum juice yields needed for theproduction of bio-ethanol
(North-West University (South Africa), 2020)
The rasionale behind this study was merely to determine whether the tested sweet sorghum genotypes can be utilised as a renewable bio-ethanol resourse and whether different nitrogen (N) application levels have an effect ...
The effect of cellobiohydrolase I on low consistency refining and handsheet properties
(North-West University (South Africa)., 2022)
Papermaking is an energy-intensive process, with mechanical pulp refining accounting for 30% of the total electrical energy consumption during papermaking. Presently, with significant economic and environmental concerns, ...
The cultivation and harvesting of micro–algal biomass from the Hartbeespoort Dam for the production of biodiesel
(North-West University, 2011)
Renewable energy sources such as biomass are becoming more and more important as alternative to fossil fuels. One of the most exciting new sources of biomass is micro-algae. The Hartbeespoort Dam, located 37 km west of ...
The development of an engineering model for the separation of CxFy gasses fluorocarbon
(North-West University, 2011)
South Africa is a land blessed with an abundance of mineral deposits. Yet, despite this, very little value adding of minerals exists. Most of the mined minerals are exported, where it is reworked into valued items. The ...
The effects of kneading and enzymatic treatments on properties of viscose-grade dissolving wood pulp
(North-West University (South Africa)., 2022)
Dissolving wood pulp (DWP) is a high-purity form of cellulose that is produced by pulping and bleaching lignocellulosic biomass to obtain a cellulose content greater than 90%. DWP is used as the feedstock for many applications ...
Bio-catalytic upgrading of phenolic components present in waste water of a hydrothermal liquefaction plant
(North-West University (South Africa)., 2021)
Vanillyl alcohol oxidase is a flavoenzyme naturally sourced from Penicillium simplicissimum. It is
a potential candidate in the commercial production of vanillin, an expensive natural flavourant in
the cosmetic, food, ...
Biodiesel production from plant oils of African origin
(North-West University, 2018)
As the search for alternative sources of energy to supplement traditional fossil-derived energy has intensified across the globe, biodiesel derived from biolipids has emerged as a promising alternative to diesel fuel. This ...
Extraction of cellulose from cacti
(North-West University, 2012)
Paraffin is used as a main household energy source for cooking, lighting and heating by
low-income communities in South Africa. It is highly inflammable and spillages from
paraffin can be considered as one of the major ...
Use of amaranth as feedstock for bio-ethanol production
(2014)
The depletion of fossil fuel reserves and global warming are the two main factors contributing to the current demand in clean and renewable energy resources. Biofuels are renewable energy resources and have an advantage ...
Separation by pervaporation of methanol from tertiary amyl methyl ether using a polymeric membrane
(Potchefstroom University for Christian Higher Education, 2003)
In this study, the sorption and pervaporation characteristics of the commercial PERVAP2256® membrane with methanol and tert-amyt methyl ether (TAME) mixtures were investigated. The feed concentration and the feed temperature ...
