Gevo, Inc. expects to supply its renewable alcohol-to-jet fuel (ATJ) ( earlier post ) to the Virgin Australia Group. The Virgin Australia Group will be responsible for coordinating the purchase, supply and blending of the ATJ into the fuel supply system at Brisbane Airport in Queensland, Australia. Gevo’s ATJ is expected to be blended with traditional jet fuel and supplied on flights departing Brisbane Airport, including Virgin Australia flights. It is currently contemplated that Gevo will ship the first gallons of ATJ to the Virgin Australia Group in October 2017. Gevo will supply the ATJ from its hydrocarbon plant based in Silsbee, Texas. The ATJ is derived from isobutanol produced at its commercial isobutanol plant located in Luverne, Minnesota. Isobutanol produced from starch or biomass is dehydrated over an acidic catalyst to produce isobutylene, which is then further reacted to product mixtures of longer chain aliphatic hydrocarbons. A portion of this material is reacted separately to form high density aromatic compounds. Hydrogen gas, a byproduct of the aromatization reaction, is used to remove unsaturated bonds in the aliphatic material. The hydrocarbons then are blended in proportions that can meet all ASTM standards for fuels: isooctane is a dimer of dehydrated isobutanol and is a major component of the premium value alkylates, a key gasoline component; a trimer of the isobutylene (dehydrated isobutanol) is a jet fuel ...
