  1. D1655 vs. D 7566 Specification Overview Joseph Sorena 11/3/2011

  2. D7566 Structure

  3. Synthetic Paraffinic Kerosene (SPK) blend components • FT SPK Table A1.1 • Lower total acid • T90-10 Min • Thermal Stability Limit Temperature Elevated to 325 C. • Anti-Oxidant Required (17 min 24 mg/L max) • Cycloparaffin 15 Mass % Max • Aromatics 0.5 Mass % Max • Carbon & Hydrogen 99.5% Min • Nitrogen 2 ppm Max • Water 75 ppm Max • Sulfur 15 ppm Max • Metals 0.1 ppm Max • Halogens 1 ppm Max • HEFA Table A2.1 • All requirements as A1.1 plus • Fame less than 5 ppm

  4. Other considerations D7566 • 50 vol % blend max of SPK with Conventional Jet • With respect to ASTM the fuel will be distributed and handled as 1655 once blended and released. • Additives are the same approved for D1655 • Synthetic Aromatics Feedstocks outside of Scope of D7566 • Alcohol to Jet • Pyrolysis oils
