Ultrasonic assisted biodiesel production
(ETA-Florence Renewable Energies, 2014)
One of the biggest hurdles in the production of biodiesel is the high production cost compared to petroleum-derived diesel. Even though the mechanical agitation utilised during biodiesel production is effective, it is ...
The evaluation of spent coffee grounds as feedstock for continuous hydrothermal liquefaction
(EARET, 2018)
This study looks at converting a low-value waste
in a continuous hydrothermal liquefaction reactor to a
high-value biocrude and biochar product. The feedstock
chosen for this study was spent coffee grounds (SCG) as
spent ...
Fuel ethanol production from sweet sorghum bagasse using microwave irradiation
(ETA-Florence Renewable Energies, 2013)
Sweet sorghum is a hardy crop that can be grown on marginal land and can provide both food and energy in an integrated food and energy system. Lignocellulose rich sweet sorghum bagasse (solid left over after starch and ...
Waste butter and margarine as feedstock for biodiesel production
(ETA-Florence Renewable Energies, 2012)
The resulting bio-waste from butter and margarine factories should be disposed of in an environmentally friendly manner. Currently the bio-waste is either flushed into the municipal sewerage system or moved to landfill ...
Catalytic hydroprocessing of ground cottonseeds in a cottonseed oil and 1-octane solvent to produce renewable diesel. (Slide presentation)
(ETA-Florence Renewable Energies, 2017)
A comparison of biodiesel purification methods
(ETA-Florence Renewable Energies, 2013)
The purification of biodiesel is of cardinal importance to ensure the final product meets industry standards. This final step in the production stage contributes a large portion of the cost attributed to biodiesel production. ...
Enzymatic recovery of water from water hyacinth
(ETA-Florence Renewable Energies, 2013)
This study sought to assess the viability of utilizing water recovered from a declared aquatic weed, Eichhornia crassipes, commonly known as the water hyacinth, for domestic, industrial and agricultural purposes. Celluclast, ...
Thermochemical liquefaction of water hyacinth
(ETA-Florence Renewable Energies, 2013)
The use of non-edible biomass should be investigated as alternatives for biofuel production. Aquatic weeds like water hyacinth (WH) are classified as third generation crops. WH in South Africa is an invasive species that ...
Fermentation of lignocellulosic biomass using ultrasonic pretreatment
(ETA-Florence Renewable Energies, 2014)
The potential fermentation of the sugars derived from water hyacinth, sweet sorghum bagasse and amaranth using indirect ultrasonic pretreatment, was investigated. The optimum sugar and ethanol yield for the ultrasonic bath ...
