Treatment of corn ethanol distillery wastewater using two-stage anaerobic digestion
In this study the mesophilic two-stage anaerobic digestion (AD) of corn bioethanol distillery wastewater is investigated in laboratory-scale reactors. Two-stage AD technology separates the different sub-processes of the AD in two distinct reactors, enabling the use of optimal conditions for the different microbial consortia involved in the different process phases, and thus allowing for ...

EU fuel quality monitoring — 2014
Each year, under the requirements of the European Union (EU) Fuel Quality Directive (FQD) (1), EU Member States must report various types of information relating to the quality of petrol and diesel fuels sold in their territories. More specifically, Member States must sample fuels each year and analyse their technical characteristics to ensure that they are consistent with the requirements of the ...

Engine detonation with bioethanol cavitation
Bioethanol is an alcohol of an organic origin which receives from a sugar ferment reaction. In the process of ethanol formation, starch from grains of plants turns in simple sugar in reaction with enzymes. Natural sugar ferments with yeast and form a mix of alcohol, water and unfermented remains. Alcohol is separated from a mix in distillation capacities and additionally clears in rectifying ...

Bioethanol mixing is the movable mechanism of fuel consumption
Bioethanol mixing is applied in automotive industry; it is enough to add 10% of ethanol in gasoline considerably to increase car power and fuel efficiency. Small concentration of ethanol in fuel (to 10%) is not significantly influences on operation of the engine, but with increase of concentration to 85% be required power supply system alteration. Considering that biofuel comes to everyday life ...

Fuel upgrading improves cars operation
Gasoline is the mix of easily boiling liquid various hydrocarbons received at distillation of oil, natural gas reclamation, processing of fuel firm types and at secondary processing of products of oil distillation. The most important for gasoline are detonation requirements and fractional structure on which their properties depend. Operation without detonation of the engine is reached by gasoline ...

The bioethanol blending with gasoline promotes its full combustion
There are actively proceeding world discussions about oil and alternative energy sources. First of all should be mentioned bioethanol, as the most capacious product. Today oil and gas are the main power sources in the world and therefore reduction of their use is the main priority in work of many countries governments. These days many farmers invest in construction of the enterprises for ...

An assessment of energy balance from sugar–based ethanol for fuel–saving and climate policy - the case of an island economy
The study assesses the efficiency of sugar–based ethanol production in Mauritius using the net energy balance and energy ratio. The findings indicate a positive net energy balance. For every one unit of fossil fuel used, the system returns more than six times in terms of renewable energy from ethanol. The fuel savings and other economic benefits which may be accrued to Mauritius are discussed. ...

Partial equilibrium analysis of the EC bioethanol blend mandate policy: its potential implications for EU transport sector
The aim of this study is to set up an EU27 bioethanol partial equilibrium model under a binding blend mandate and to determine the bioethanol market clearing conditions' implications on EU transport sector. Bioethanol supply is derived from EU27 bioethanol crops while its demand is a derived from that of transport fuel in the region. Results show that equilibrium bioethanol quantities at 70% tax ...

A co-beneficial system using aquatic plants: bioethanol production from free-floating aquatic plants used for water purification
A co-beneficial system using constructed wetlands (CWs) planted with aquatic plants is proposed for bioethanol production and nutrient removal from wastewater. The potential for bioethanol production from aquatic plant biomass was experimentally evaluated. Water hyacinth and water lettuce were selected because of their high growth rates and easy harvestability attributable to their ...

Anaerobic digestion of stillage fractions – estimation of the potential for energy recovery in bioethanol plants
Stillage processing can require more than one third of the thermal energy demand of a dry-grind bioethanol production plant. Therefore, for every stillage fraction occurring in stillage processing the potential of energy recovery by anaerobic digestion (AD) was estimated. In the case of whole stillage up to 128% of the thermal energy demand in the process can be provided, so even an ...

Assessment of hemicellulose extraction technology for bioethanol production in the emerging bioeconomy
Rising energy costs, climate change and fossil fuel consumption are driving global efforts to transition toward a sustainable 'green' bioeconomy. This pursuit of bioeconomy requires billion tons of feedstocks, development of biomass-based technologies and biorefineries under the overarching principle of sustainability. First generation ethanol has helped to effectively manage the increasing ...
