Advanced aircraft-fuel evaluation. Phase 1. Final report, June 1986-January 1987

TL;DRAbstract

The objective of this project was to provide estimates of the availability, cost, and quality of naphthenic hydrocarbon fuels for advanced hypersonic vehicle propulsion as a function of time. To accomplish this objective, a proposed specification of the fuel was established. Potential sources of feedstocks were surveyed with particular attention to petroleum-based refinery streams. Three promising feedstocks were identified in addition to purchased petroleum-derived naphthalene, which served as the bases of comparison. Processing routes to convert the identified feeds to specification fuel were identified. These are based on existing refining technology and require no process innovation or research for successful fuel production. The samples of the proposed fuel substantially met the desired properties of the advanced fuel. In addition, rate constants were derived for the hydrogenation of naphthalene and the cis--trans-isomerization of decalin. Other rate constants relevant to the prod
