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 ...
Ultrasonic assisted amaranth stem pretreatment for bio-ethanol production
(ETA-Florence Renewable Energies, 2015)
An investigation was undertaken to determine the effect of ultrasound on enzymatic hydrolysis rate and enhanced bioethanol yields. Compositional analysis of the feedstock reveals that amaranth lignocellulose contains 36.35% ...
Bio-butanol fermentation using clostridium acetobutylicum and clostridium tetanomorphum in modified bioreactor flasks
(ETA-Florence Renewable Energies, 2015)
An alternative new generation biofuel to bio-ethanol has attracted researchers to investigate various approaches for optimization of traditional ABE fermentation to enable bio-butanol to be produced cheaper at an industrial ...
Production of value-added products from biodiesel derived crude glycerol
(ETA-Florence Renewable Energies, 2015)
Crude glycerol, a by-product of biodiesel production which contain impurities such as methanol, triglycerides and catalysts, would represent a huge challenge to the environment if disposed. Thus the best opportunity is to ...
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. ...
Enhancement of bio-methane production by lignocellulose substrates
(ETA-Florence Renewable Energies, 2015)
In this study, water hyacinth, sweet sorghum bagasse and amaranth stems were used in a pig manure matrix to produce biogas with a high methane content. The anaerobic digestion was monitored over a period of 40 days, after ...
The hydrotreatment of an unsaturated fatty acid vegetable oil to hydrocarbons over Ni/SiO2-Al2O3
(ETA-Florence Renewable Energies, 2015)
In this study, sunflower oil was hydrotreated in the presence of a nickel catalyst with the objective to evaluate the effect of reaction parameters on the characteristics of the reaction product. The effect of reaction ...
Production of bio-degradable polyurethane foam from sugarcane bagasse and biodiesel-derived crude glycerine
(ETA-Florence Renewable Energies, 2015)
As the threat of the depletion of fossil based fuels becomes more of a reality, there is a need to find alternative carbon sources for the production of a wide range of chemicals, polymers and plastics. One plastic that ...
