Described here are the ethanol heterogeneous catalytic transformations to higher value-added products such as hydrogen (H2), ethylene (C2H4), Guerbet condensation products (mostly 1-butanol), the Lebedev dehydration product ...

Ethanol production from sugarcane, mainly in Brazil, on the basis of first-generation technology (22.5 billion liters, in 2007/2008 season, in 3.4 million hectares) replaces 1% of the gasoline used in the world today and ...

Corn ethanol produced in the US and sugarcane ethanol produced in Brazil are the world`s leading sources of biofuel. Current US biofuel policies create both incentives and constraints for the import of ethanol from Brazil ...

During alcoholic fermentation, most of the substrates supplied to the yeasts are converted into ethanol and carbon dioxide generating energy for cell maintenance. However, some of these substrates end up being diverted to ...

The ethanol industry in Brazil is going through a period of stagnation, resulting in the reduction of ethanol supply. The ethanol for automotive purposes may be anhydrous, which is used as an anti-detonating additive to ...

The final levels of ethanol (levels of ethanol produced plus that added initially to the media) reached by the thermotolerant yeasts were highest (16.5-20.3%, v/v) at 8% initial ethanol. The thermotolerant yeasts were found ...

The ethanol accumulated in the broth during fermentation is the main component toxic to yeast, causing slower yeast growth and decreased ethanol production. One way of overcoming this inhibition effect is to use extractive ...
