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 ...
Chemical and structural characterization of char development during lignocellulosic biomass pyrolysis
(Elsevier, 2017)
The chemical and structural changes of three lignocellulosic biomass samples during pyrolysis were investigated using both conventional and advanced characterization techniques. The use of ATR-FTIR as a characterization ...
Chemical and physical characterization of spent coffee ground biochar treated by a wet oxidation method for the production of a coke substitute
(Elsevier, 2020)
Coke production relies on the availability, cost and quality of coking coal. Depleting coking coal resources and environmental pressure force the metallurgical industry to search for alternative methods to produce coke. ...
Preparation of biochars for co-gasification from sweet sorghum bagasse
(ETA-Florence Renewable Energies, 2015)
Biochar is a solid product obtained through torrefaction, liquefaction or pyrolysis of organic material. It can be used for soil amendment, activated carbon for sequestration, or as bio-coal for gasification or co-gasification. ...
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 ...
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. ...
Adsorption of metal ions from fine coal tailings dump waste water using bio-char
(EARET, 2018)
Coal mining operations produce large amounts of
tailings which contains heavy metals. Heavy metals such as
cadmium (Cd) can cause environmental problems. The adsorption
capacities of biochars produced from spent coffee ...
Hydrothermal preparation of biochar from spent coffee grounds, and its application for the removal of cadmium from coal tailings leachate
(SAIMM, 2019)
Spent coffee grounds were transformed into biochar using a hydrothermal method. Some of the biochar
product was pre-treated through surfactant impregnation with sodium dodecyl sulphate (SDS) to
enhance its adsorption ...
