REPORT ON THE JUNE 3-5, 2008, MEETING OF ASTM SUBCOMMITTEE D02.J ON AVIATION FUELS IN WARSAW, POLANDThe agenda for the meeting of ASTM Subcommittee D02.J on Aviation Fuels held in June 2008 is geared to the pertinent discussions concerning aviation turbine fuels and aviation gasoline, since there is much interest for the approval of biomass-produced fuels that would help reduce key greenhouse gases such as carbon dioxide (CO 2 ). In addition to these topics, task force meetings were held to…, Section J01 on Jet Fuel Specifications, - The progress made in Section J01 includes but was not limited to: -A description of a generic Fischer-Tropsch derived product known as synthesized paraffinic kerosine (SPK) is being developed for use in blending jet fuel at levels up to 50% (by volume). This will be balloted for inclusion in the jet fuel specification (ASTM D1655 , Standard Specification for Aviation Turbine Fuels) when the…, Section J06 on Emerging Aviation Fuels, -, Section J06 is a new start-up group. Their actions at the meeting were: -Opened with a discussion of the current state of alternative turbine fuels. So far, synthesis gas derived hydrocarbons are the only alternative blend stream approved or nearly approved for use in jet fuel. Their approval resulted from the efforts of SASOL, which developed synthetic jet fuel blend stocks back in the 1990s and…, Section J04 on Additives and Electrical Properties, -, Topics discussed included:, -During the session it was agreed to ballot for membership approval the new Standard Practice Guideline for the Qualification and Approval of New Aviation Turbine Fuels and Fuel Additives, as a replacement for the current words in ASTM D4054 (same title). This guideline provides a framework for the qualification and approval of new fuels, including alternative fuels and new fuel additives for use…
