“…High energy density fuel with high density and volumetric energy content (or heating value) can provide more propulsive energy than traditional aviation fuels obtained from refinery [1][2][3][4][5]. Since it can significantly promote the flight distance and loading of aircrafts, the synthesis of high energy density fuel has attracted increasing interests.…”

Synthesis of exo-tetrahydrodicyclopentadiene (exo-THDCPD) through the isomerization of endo-tetrahydrodicyclopentadiene (endo-THDCPD) was investigated over HY zeolite catalysts. Conversion of endo-THDCPD increased with the increase of Si/Al2 ratio of HY zeolite catalysts, which can be attributed to increase of acid strength with increase of Si/Al2 ratio. Yield of exo-THDCPD, however, was the highest over HY with Si/Al2 ratio of 30, because the production of cyclopentadiene and oligomers was minimized. The optimal reaction temperature was 180 ℃ because the higher reaction temperature increased the production of by-products. The yield of exo-THDCPD also increased with the amount of the catalyst in feed. In the isomerization reaction of endo-THDCPD using the HY zeolite catalysts, it was confirmed that the internal diffusion resistance in the pore of catalysts would have more significant effects on the reaction activity than that of the external diffusion resistance of catalysts.

“…1 The oligomers of DCPD, tricyclopentadiene (TCPD), and tetracyclopentadiene (TeCPD) have attracted a great deal of attention as high-energydensity fuel (HEDF). [1][2][3][4][5][6] Due to the the high density of TCPD and TeCPD, they have high volume energy contents and superior stability. The oligomer of DCPD is generated via the Diels-Alder addition reaction with cyclopentadiene (CPD), attained from the cracking of DCPD (Scheme 1).…”

The objective of this study is to evaluate the catalytic potential of metal oxide/MCM-41 catalysts in dicyclopentadiene oligomerization/dicyclopentadiene oligomer isomerization. Molybdenum oxide, tungsten oxide, and titanium oxide were loaded on MCM-41 using the modified atomic layer deposition method. The amount of the acid site with weak strength has been increased through metal oxide deposition. The oligomer yield in dicyclopentadiene oligomerization/dicyclopentadiene oligomer isomerization did not change with increasing of the amount of acid site. The highest tricyclopentadiene isomer selectivity over the MoO3/MCM-41 catalyst could be attributed to having the highest overall number of acid sites among the catalysts.
