摘要：

In order to reduce the amount of palladium catalysts in hexabenzylhexaazaisowurtzitane (HBIW) hydrogenolysis, a precipitation-reduction method of synthesizing palladium-based bimetallic catalysts were proposed. Catalysts on different supports were examined and optimized. Effects of supports, metal promoters, palladium mass fraction in the catalyst, mass ratio of catalyst to HBIW on the reaction yield were investigated. The results show that 5 % Pd-Ni/γ-Al2O3 is the optimal catalyst for the hydrodebenzylation of HBIW. Under the reaction conditions of 0.5 g HBIW, 0.0375 g catalysts, 0.4 MPa H2, 15 ℃ for 8 h and then 45 ℃ for 24 h, product yield of 85% can be achieved. The mass ratio of palladium to raw material HBIW was 0.375% under such conditions. Under the conditions of 392 ms2 acceleration, 0.5 g HBIW, 0.4 MPa H2, the reaction time is shortened to 100 min in a resonant acoustic reactor with 85% product yield. © 2023 Zhejiang University.
