Abstract : When development of aqueous fire-resistant diesel fuel (FRF) was previously reported, it was shown that clear-to-hazy water-in-fuel, diesel fuel micro-emulsions could be prepared and that they exhibit reduced mist flammability and self-extinguishing pool fires at temperatures above the base fuel flash point. It was also demonstrated that unmodified diesel engines start, idle, and run without difficulty on such fuels. Research has been continued to establish compositional requirements for base fuels, surfactants, and water used in FRF formulations. DF-2, DF-1, DF-A, and NATO diesel fuel samples were obtained from refineries, bulk storage, and service stations. Aromatic concentrate (AC) products from various sources were evaluated for use in adjusting the total aromatic ring carbon (TARC) content of FRF formulations. Neat base fuel and AC-containing base fuel TARC effects on microemulsification efficacy were established for water containing various amounts of total dissolved solids and for the amide/amine/soap emulsifier with various levels of total acid number.
