Abstract:

The oligomerization of endodicyclopentadiene（endo-DCPD）in a continuousflow reactor at elevated pressure was studied to produce tricyclopentadiene（TCPD）that was the precursor of highenergydensity fuelThe composition of the products and possible reaction pathway were analyzed，and the effects of reaction conditions were evaluatedCompared with the batchwise reaction at atmospheric pressure，the continuousflow process could significantly enhance the reaction，increase the exo/endo ratio of TCPD，and produce a new product exo-DCPDThe exo/endo ratio was linearly dependent on the selectivity of exo-DCPDA high pressure of above 1.2 MPa was necessary to facilitate the reactionThe conversion of endo-DCPD increased with the increase of temperature，while the yield of TCPD reached the highest value at 160℃But the exo/endo ratio decreased with the increase of temperatureThe conversion of DCPD and the yield of TCPD increased when the residence time was increased，but the reaction rate decreasedA short residence time was favorable，because it led to a high exo/endo ratio for TCPDThe effect of feed concentration was limitedUnder the optimal condition，the conversion of endoDCPD was 82.2% and the yield of TCPD was 41.7%.
