Production of ethanol from sweetstem sorghum and tropical sugar beet for a rural community
(ETA-Florence Renewable Energies, 2011)
Rural communities in the North West Province of South Africa are among the poorest in the world with an average income of less than ZAR 8.75 (EU 0.875) per day. The South African government has committed itself to upliftment ...
Conceptual cost of an integrated micro-algal biomass-to-liquids facility
(ETA-Florence Renewable Energies, 2011)
An orderofmagnitude cost estimate was conducted on a new integrated biomasstoliquids (BtL) process that produces 2.6 million litres of biodiesel per year from microalgal biomass harvested from the Hartbeespoort Dam. ...
Feasibility of cultivating Hartbeespoort Dam microalgae
(ETA-Florence Renewable Energies, 2011)
Three cultivation experiments were conducted to grow microalgae in three consecutively scaled-up laboratory systems, which consisted of one, five and 135-litre bioreactors. The highest productivity achieved under optimum ...
Four novel methods for the harvesting of micro-algal biomass
(ETA-Florence Renewable Energies, 2011)
The harvesting of micro-algal biomass is one of the most inefficient and costly steps in the whole biomass-to-liquids (BtL) value chain. Harvesting costs may contribute between 20–30% of the total cost of microalgal BtL ...
Conceptual design of an integrated micro-algal biomass-to-liquids process
(ETA-Florence Renewable Energies, 2011)
A new integrated biomasstoliquids conceptual process was developed to produce 2.6 million litres of biodiesel per year from harvested microalgal biomass. Three unconventional harvesting methods, a thermochemical ...
Bio-oil and bio-char production from sunflower hulls
(ETA-Florence Renewable Energies, 2011)
In this paper, the hydrothermal liquefaction of sunflower hulls into biooil and biochar is presented. The main manipulated variables that were studied were biomass load, catalyst type and temperature. The experimental ...
