Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil. by Brian J.

Consequently, first and second generation bioproduct manufacturing processes are economically challenged, particularly in light of recent low oil prices. One way to mitigate high feedstock cost is to maximize conversion into the bioproduct of interest. In this study, researchers tested how C. Jones, Alan G. Fast, Ellinor D.

PNAS study finds Vertimass CADO efficient way to convert ethanol to biohydrocarbons; 40 to 96% reduction in GHGs, based on feedstock

Green Car Congress

Unlike prior processes for converting alcohols into hydrocarbons with multiple steps for dehydration, oligomerization, and hydrogenation, the Vertimass consolidated alcohol dehydration and oligomerization (CADO) conversion is accomplished in a single reactor system using a metal exchanged zeolite catalyst.

It’s a robust technology, but you have to pay the oil price, and if you have to burn an awful lot of heat in order to enable that endothermic chemistry, if you were to care about the energy footprint of this, it’s the three pounds of CO 2 produced to make one pound of polyethylene. ” —Alex Tkachenko.
