High‐density fuel was prepared by catalytic dimerization and subsequent hydrogenation. Different amounts of phosphotungstic acid (H3PW12O40, HPW) were loaded on mesoporous silica (SBA‐15) by a simple impregnation method to prepare HPW/SBA‐15 catalysts. The prepared catalysts were mesoporous. Characterizations indicated that the dispersion and the specific surface area depend on the HPW amount. The obtained dimers from catalytic dimerization of β‐pinene underwent isomerization and then dimerized to form the heterogeneous products. At the optimum load of HPW, the HPW/SBA‐15 catalyst displayed the highest catalytic activity and the increased yield of dimer for a 3‐h reaction. After the subsequent hydrogenation reaction, the obtained hydrogenated dimer products displayed a density and a volume calorific value comparable to those of commercial JP‐10.

β-P烯二聚法制备高密度燃料

高密度燃料是通过催化二聚反应和随后的氢化反应制得的。通过简单的浸渍方法将不同数量的磷钨酸(H 3 PW 12 O 40,HPW)负载在介孔二氧化硅(SBA-15)上,以制备HPW / SBA-15催化剂。制备的催化剂是中孔的。表征表明,分散体和比表面积取决于HPW的量。β催化二聚得到二聚体对pine烯进行异构化,然后二聚形成异质产物。在HPW的最佳负载下,HPW / SBA-15催化剂在3小时的反应中显示出最高的催化活性和增加的二聚体产率。在随后的氢化反应后,所获得的氢化二聚产物显示出的密度和体积热值可与市售JP-10媲美。
