The catalyst HPMo/SBA-15 was prepared by loading the phosphomolybdic acid(HPMo) on the SBA-15, which was prepared by tetraethyl orthosilicate and triblock copolymer(P123).The dimerization of β-pinene was catalyzed by HPMo/SBA-15, and then the dimer product was hydrogenated by Pd/C catalysis to produce high density fuel. The structure of HPMo/SBA-15 was characterized by FT-IR, XRD and N2 adsorption-desorption analysis. The catalytic performance of HPMo/SBA-15 catalysts with different loading amount for β-pinene dimerization was also studied. The results showed that the prepared HPMo/SBA-15 catalyst had mesoporous characteristics.HPMo dispersed evenly in the SBA-15 when the loading amount of HPMo ≤ 80%; when the loading amount was 100%, the HPMo was unevently distributed, aggregated on the surface of molecular sieves and blocked the hole, which resulted in the decrease of HPMo/SBA-15 surface area. The catalytic activity of 80% HPMo/SBA-15 was the highest, and the yield of dimer reached 63.3% after 4 h reaction at 150℃.The density and volume calorific value of high density fuel obtained from hydrogenated dimer product were similar to those of JP-10. However, the large viscosity, the high density fuel could not be used as fuel alone, could only be used as additives with other fuels.
