In-situ biodiesel production from sunflower seeds using liquefaction
(ETA-Florence Renewable Energies, 2015)
One of the most expensive steps in the bio-diesel value chain is the extraction of oil from the seeds. Simultaneous extraction and transesterification will lower the overall capital costs of the process while enhancing ...
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 ...
