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. ... -
Co-pyrolysis of coal and raw/torrefied biomass: a review on chemistry, kinetics and implementation
(Elsevier, 2021)Thermochemical conversion via co-pyrolysis has the potential to be an efficient route for converting biomass to bio-energy and bio-refinery products. In this review, the implementation of co-pyrolysis of torrefied biomass ... -
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. ... -
Effect of temperature on density, sound velocity, and their derived properties for the binary systems glycerol with water or alcohols
(Elsevier, 2017)Densities and sound velocities of three binary systems containing glycerol + (water, methanol, or ethanol) have been measured over the entire composition range at temperatures ranging from (283.15 to 313.15) K in 10 K ... -
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, ... -
Forb ecology research in dry African savannas: knowledge, gaps, and future perspectives
(Wiley, 2019)Savannas are commonly described as a vegetation type with a grass layer interspersed with a discontinuous tree or shrub layer. On the contrary, forbs, a plant life form that can include any nongraminoid herbaceous vascular ... -
The influence of selected biomass additions on the co-pyrolysis with an inertinite-rich medium rank C grade South African coal
(SAIMM, 2015)Co-pyrolysis of four biomass samples (hardwood chip, softwood chip, pinewood chip, and sugarcane bagasse) with an inertinite-rich medium rank C South African coal was investigated. Proximate and ultimate analyses of the ... -
Overview and status of estuarine microphytobenthos ecological research in South Africa
(Taylor & Francis, 2018)This article presents a historical overview of estuarine microphytobenthos (MPB) research in South Africa published over the period 1950 to the present, highlighting major milestones, challenges and estuarine management ... -
Performance assessment of an improved cook stove (Esperanza) in a typical domestic setting: implications for energy saving
(Springer, 2017)Background: Much of the Malawi's energy source, which is biomass, is consumed using traditional household technologies. These technologies contribute to over consumption of biomass leading to increased forest degradation, ... -
Photosynthetic responses of canola and wheat to elevated levels of CO2, O3 and water deficit in open-top chambers
(MDPI, 2019)The effects of elevated CO2 (700 ppm) and O3 (80 ppb) alone and in combination on the photosynthetic efficiency of canola and wheat plants were investigated in open-top chambers (OTCs). The plants were fumigated for four ...
