摘要：Dicyclopentadiene (DCPD) resin polymerized by DCPD contains a large number of unsaturated bonds, hydrogenation plays an important role in enhancing its thermal stability and decoloring. Herein, a series of supported Cu-Ni-Al catalysts with high distribution and large surface areas derived from direct reduction of hydrotalcite-like compounds have been synthesized. The hydrogenation properties of supported Cu-Ni-Al catalysts for the DCPD resin and its monomer have been investigated. The Cu1Ni3-Al2O3 catalyst shows the highest DCPD conversion (>99%) and selectivity to tetrahydrodicyclopentadiene (THDCPD) (>98%) under mild conditions (40 degrees C, 2 MPa H-2) compared with the corresponding catalysts prepared by impregnation and mechanically mixed method. Due to the high particle dispersion of active-sites and the synergistic effect between metallic Cu and Ni, the optimal catalyst (Cu1Ni3-Al2O3) also presents an expected catalytic activity in the hydrogenation of DCPD resin.
