Evaluation of bio-char based products as hydrotreating catalysts for the production of renewable fuel
(2017)
Increasing demand for alternative fuel from fossil fuel exists which has led to the development of new technologies for the production of bio-fuels. One such technology involves the hydrotreatment of vegetable oils such ...
Green coal development for application in fixed-bed catalytic gasification
(SAIMM, 2018)
A novel ‘green coal’ product formulation has recently been developed and
the utilization concept tested at the North-West University coal research
laboratories. Hydrothermal liquefaction was used to produce bio-oil ...
Amaranth lignocellulose as feedstock for bioethanol production: effect of microwave-assisted alkaline pretreatment on reducing sugar yield
(ETA-Florence Renewable Energies, 2014)
A new class of lignocellulose derived from amaranth (Amaranthus Cruentus) represents a potential feedstock for bioethanol production. The lignocellulose material can be pretreated to yield high monomeric sugar concentrations ...
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 ...
Predictive model for fuels from hydrothermal liquefaction of municipal solid waste
(EUBCE, 2019)
Effective management of the environmental impact of municipal solid waste (MSW) is a global issue linked to urbanization and a rapid increase in the global population. Although MSW has been evaluated as possible feedstock ...
Valorisation of waste lignin for phenol derivative compounds using hydrothermal liquefaction
(EUBCE, 2019)
Approximately 95% of global phenolic compounds (such as catechol, guaiacol, syringol, and vanillin) used in the pharmaceutical, fragrance and industrial industries are produced from petroleum-based phenolics such as benzene. ...
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 ...
Effect of biomass feedstock composition on biochar properties produced through hydrothermal liquefaction
(EARET, 2018)
The effect that 6 different biomass feedstocks have
on biochar was investigated. The biochar was produced through
hydrothermal liquefaction at temperatures of 260˚C and 300˚C.
The effect of temperature was also investigated. ...
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 ...
