increasing. In Brazil - mainly at Sao Paulo State -, sugarcane ethanol is being intensively produced on large-scales, giving rise … to social and environmental concerns about its production. If ethanol production systems are to maintain a balance … large-scale ethanol production. For this, embodied energy analysis, emergy accounting, ecological rucksack and gas emission …

Ethanol production from cellulosic sources such as switchgrass (Panicum virgatum L.) requires the use of natural … amount of environmental, fossil fuel, and human-derived energy required to produce ethanol from switchgrass. Emergy is the … directly or embodied in purchased goods, and 25% came from human-derived services indirectly. Ethanol production per petroleum …

Sugarcane is one of the most important industries of the Brazilian economy, and its main products are sugar and ethanol … analysis is used to assess an integrated sugar and ethanol plant with its cogeneration system. The plant was divided into eight …, which produce sugar and ethanol, were used in the process simulation. The analysis has shown that the sub-systems with the …

In this paper an exergy analysis of thermochemical ethanol production from biomass is presented. This process combines … ethanol. The production process involves several process sections, including biomass drying and gasification, syngas cleaning …, reforming, conditioning, and compression, ethanol synthesis, separation of synthesis products, and heat recovery. The process is …

Sugarcane bagasse and trash may be used as feedstock for second generation ethanol production. Production of second … generation ethanol integrated with first generation plants processing sugarcane presents several advantages over the stand …-alone second generation ethanol production process; however, bagasse is used as fuel to supply the energy demand of the first …

renewable and environmental friendly energy sources to supplement and replace fossil fuels. Ethanol has been an appropriate … substitute to fossil fuels. Currently, E10 and E85 are two of the main transportation fuels with ethanol and they are competing … and other government policies to promote the ethanol industry. …

The Dynamic Adaptive Chemistry (DAC) technique is extended in this work to multidimensional simulations of ethanol HCCI …/PSCCI engines. Several DAC computations have been performed by using two kinetic reaction mechanisms of ethanol with different … accurate results, in terms of pressure and heat release rate profiles and CO, CO2 and UHC emissions, are obtained with ethanol …
