We examined the effects of different ethanol and iso-butanol blends on the gaseous and particulate emissions from two … fuel effects. Formaldehyde and acetaldehyde were the main carbonyls in the exhaust, with the higher ethanol blends showing … different butanol blends when compared to ethanol blends, but not for all cases. The higher ethanol and butanol blends showed …

recovery. Thus, the aim of this study is to assess the incorporation of double-effect distillation in ethanol production, and …

Sugarcane ethanol biorefineries in Brazil produce carbon dioxide, electricity and heat as byproducts. These are … essential inputs for algae biodiesel production. In this paper, we assessed ethanol's life cycle greenhouse gas emissions and … sugarcane ethanol by around 10% and 50%, respectively, compared to a traditional Brazilian sugarcane ethanol distillery. …

India's biofuel programme relies on the ethanol from molasses for blending into gasoline. Therefore, quantification of … GHG (green house gas) emissions and the energy consumed during the process of ethanol production is desirable to help … assessment) is conducted for 1 ton of fuel grade ethanol in the NR (northern region) and WR (western region) of India. Four …

This study carried out an exergetic analysis of a proposed ethanol production scheme in which a new process – enzymatic … conventional ethanol production plant without hydrolysis, a conventional plant combined with hydrolysis and hydrolysate … with their exergetic cost. For the conventional process, in which ethanol and surplus electricity are the major products, a …

A transient-state mathematical model for an ethanol basin solar still based on Spalding's work was developed. Driving … ethanol basin solar still was tested under outdoor conditions. The model had RMSEs of 4% and 23% of the measured mean … simulated distillate concentrations were 74, 59 and 24%v/v for ethanol solution concentrations of 50, 30 and 10%v/v. The monthly …

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 …
