Page: Bioethanol production of 2nd generation
Brazil, the production of bioethanol is based on sugar cane as feedstock, in the US and Europe, bioethanol is produced primarily from starch (cereal and corn). The European market in biofuels is expected to increase considerably in the near future. Within the next decade, a wider use of renewable ...

Page: Fermentation
Lignocellulosic biomass is hydrolyzed by explained treatments (mostly by acid treatment) (chapter "Hydrolysis of lignocellulosic biomass). The obtained hydrolysate (mixed sugarsolution) is then fermented by microorganisms (e.g. bacteria, yeast). This hydrolysate (mixed sugarsolution) often contains not only glucose, but also other ...

Page: Hydrolysis of lignocellulosic biomass
Hydrolysis is a chemical process, where a molecule is cleaved into two parts by adding a molecule of water. One fragment of the molecule gains a hydrogen ion (H ). The other group collects the remaining hydroxyl group (OH − ). After pretreatment of lignocellulosic material, the cellulose ...

Page: Pre-treatment
Firstly, lignocellulosic material has to be sizereduced and pretreated for alteration and removal of structural and compositional impediments (physical disruption) to hydrolysis. Therefore, the rate of enzymatic hydrolysis as well as yields of accessible, fermentable sugars from cellulose and hemicellulose can be increased. Through pretreatment ...

Page: Processing of lignocellulosic material to bioethanol
conversion of lignocellulosic material to monomeric sugars (e.g. C5 and C6 sugars) is more difficult than the conversion of starch. There are numerous features, which have to be considered additionally, compared to bioethanol production using sugar\ or starchbased feedstocks. One of them is an ...

Page: Product and solids recovery
When fermentation products are more volatile than water, recovery by distillation is often the used technology. Distillation means, that the bioethanol is separated from water in the liquid mixture. In virgin bioethanol, the content of water is normally higher than 80 %. In order to concentrate ...

Page: Social, political and economical relevance
Because of its great availability and low costs, lignocellulosic biomass is the most promising feedstock for production of fuel bioethanol. Nevertheless, the largescale commercial production of bioethanol from lignocellulosic materials has still not been implemented. Different feedstocks (e.g. sucrose ...
