Abstract: JET FUELS WHICH HAVE BOTH A HIGH HEAT CONTENT AND AN ACCEPTABLE LOW TEMPERATURE VISCOSITY ARE PREPARED BY THE HYDROALKYLATION OF MONONUCLEAR AROMATIC HYDROCARBON FRACTIONS. BENZENE, TOLUENE, AND UNDEX EXTRACT, AND MIXTURES THEREOF, ARE THE PREFERRED STARTING MATERIALS. THESE ARE HYDROALKYLATED BY REACTION AT ABOUT 30*-250*C. UN DER SUPER-ATMOSPHERIC PRESSURE OF ABOUT 20-70 ATMOSPHERES OF HYDROGEN, THUS PRODUCING HYDROALKYLATES CONTAINING CYCLOALKYL-SUBSTITUTED BENZENES, METHYLCYCLOHEXYLSUBSTITUTE TOLUENS AND THE LIKE. THESE ARE FURTHER REDUCED TO THE CORRESPONDING CYCLOALKYL-SUBSTITUTED CYCLOHEXANES, TOGETHER WITH METHYLCYCLOHEXYL METHYLCYCLOHEXANES AND METHYLCYCLOHEXANE WHEN TOLUENE IS USED, AND THE REDUCTION PRODUCTS ARE ADJUSTED TO A FINAL DESIRED HEAT CONTENT AND LOW TEMPERATURE VISCOSITY BY STRIPPING OFF OR ADDING METHYLCYCLOHEXANE. THE PREFERRED CATALYST IS FINELY DIVIDED NICKEL ON A SUPPORT CONTAINING BOTH A ZEOLITE AND A SILICA-ALUMINA CRACKING CATALYST.
