NARA member receives approval for bio-jet fuel

The Northwest Advanced Renewables Alliance (NARA) congratulates our fuels partner, Gevo, Inc. for ASTM International’s inclusion of Gevo’s alcohol to jet (ATJ) synthetic paraffinic kerosene (ATJ-SPK) into ASTM D7566 (Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons). This inclusion makes Gevo’s ATJ-SPK eligible to be used as a blending component, up to 30%, in standard Jet A-1 fuel used by commercial airlines in the United States and in many other countries around the globe.

As previously announced, …more

Pretreatment is the process that breaks up major wood components (lignin and polysaccharides like hemicelluloses and cellulose) so that enzymes can degrade (hydrolyze) the polysaccharides into simple sugars. Effective pretreatment and hydrolysis are necessary to achieve high sugar quality and yield. The sugars derived from the pretreatment/hydrolysis process can serve as a …more

Extractives found in post-harvest forest residuals

sap-112363_1920

When it comes to evaluating an industry that uses post-harvest forest residuals (slash) to make bio-jet fuel and co-products, the primary components in softwoods, like Douglas-fir, receiving the most industrial interest are cellulose, hemicellulose and lignin. The cellulose and hemicellulose contain the simple sugars used to biofuel and other chemical products. The lignin is a byproduct of the fuel conversion process and can be used to make additional products like …more

Single trailer chip truck loading post-harvest forest residuals

Using post-harvest forest residuals, or slash, to make biojet fuel and co-products is an economic challenge. A significant cost in the supply chain is transportation associated with hauling the processed slash material to a conversion facility. To supply slash material to a conversion facility or processing depot, trucks need to travel …more
