Abstract : The general objective of the investigation was the development of new hydrocarbon fuels and new fuel systems which will meet the cooling and propulsion requirements of advanced air-breathing engines. The preparation of catalysts for both packed bed and catalyst lined reactors and the evaluation of catalyst activity and stability for the dehydrogenation of methylcyclohexane and Decalin is discussed. Several catalyst lined reactors were tested under realistic heat transfer and reaction conditions. The Beta-Ray Deposit Rater was developed, tested, and used to rate coke deposits on tubes from thermal stability tests. The effects of various stability additives in different fuels were investigated. Viscosities of different hydrocarbons, including SHELLDYNE-H and SHELLDYNE-H/hydrocarbon mixtures, were measured. The effects of exposure to elastomers on the properties of SHELLDYNE-H fuel were analyzed. Ignition delay times and combustion rates were measured for Decalin and its dehydrogenation products. A bibliography of current articles and patents of interest to this and related programs is included. (Author)
