18 April 2018 - The Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, as well as their D02.J0 Sub-committee on Aviation Fuels, have approved the co-processing of renewable feedstocks with crude oil-derived middle distillates in petroleum refineries. The concurrent ballot was issued in February to the subcommittee and committee. The co-processing provision will be added to Annex A1 of ASTM D1655, Standard Specification for Aviation Turbine Fuels, and should be published imminently. The Annex will initially include co-processing of up to 5% by volume of fats and oils (free fatty acids and fatty acid esters found in oils derived from plants and animal fats) as feedstocks in petroleum refinery processes. The Co-processing Task Force will next work toward adding Fischer-Tropsch (FT) derived biocrude feedstocks to the annex. CAAFI welcomes this additional approach toward alternative jet fuel commercialization, and looks forward to further engagement with existing refineries on ways to achieve increasing volumes of sustainable fuel production.
