EPA approves Algenol ethanol as RFS advanced biofuel with D5 code; 69% reduction in GHG compared to gasoline

Green Car Congress

The US Environmental Protection Agency (EPA) has approved ethanol made from Algenol’s process as an advanced biofuel, meeting the Greenhouse Gas (GHG) reduction requirements under the Renewable Fuels Standard (RFS). EPA currently has five RIN D-codes (D3, D4, D5, D6 and D7). The EPA approval is a milestone event for Algenol.

2013 SAE International High Octane Fuels Symposium (HOF): the potential for high octane fuels (Part 1)

Green Car Congress

With the spread of turbocharged gasoline engines, he added, there is a double benefit: higher compression ratios and increased boost. Octane itself is a C 8 hydrocarbon with 18 structural isomers, and is a component of gasoline. Straight-run gasoline in the refinery (naphtha) has a poor octane rating on the order of 40-50 RON.
