Modulating temporal temperature pattern of dicyclopentadiene conversion reaction network for efficient production of tricyclopentadiene

Abstract

Tricyclopentadiene (TCPD) has received widespread attention as a competitive precursor of high-performance liquid fuel with a density greater than 1 g/cm³. However, the efficiency of TCPD synthesis using the traditional heating method is still low due to the difficulty in regulating the reaction network for suppressing side reactions. Because the temporal temperature profile can not be finely tuned in the traditional reactor. Herein, the programmed temperature-controlled electrical heating (PCH) technique is employed to realize transient temperature control of the reaction system. The optimal reaction conditions are determined by Bayesian optimization method for improving the yield of TCPD. In continuous flow reaction, a TCPD yield of 66.39 % is achieved using PCH, which is only 32.84 % by the traditional continuous heating method. The space-time yield of TCPD is increased from 5.71 g/h to 11.47 g/h. This work provides a new perspective on the network regulation of traditional thermochemical reactions.
