Abstract Recently, great efforts have been devoted to the production of higher alcohols (C2+ alcohols) by chemical synthesis, but it's still quite challenging for the related heterogeneous catalysis. In this work, the hydrogenolysis of sugar alcohols derived from biomass was proposed to efficiently synthesize higher alcohols over the Ru-Mo/CMK-3 catalyst. The C C and C O bonds in sorbitol were positively broken to form C2+ alcohols, while the excessive cleavage of C O bonds to form C1–C6 alkanes was effectively suppressed. The experimental results indicated that the yield of C2+ alcohols in the products reached 49.0%, and that of C5+ alcohols reached 29.9% in a continuous flow reactor. Preliminary experimental results and catalyst characterization supported that the synergetic effect of Ru and Mo species, different Ru precursors and the mesoporous channel effect of CMK-3 carrier were the key to such high reactivity.

Ru-Mo/CMK-3催化剂上糖醇水相氢解制高级醇

摘要 近年来,通过化学合成制备高级醇(C2+醇)的研究已经取得了很大的进展,但相关的多相催化仍然具有很大的挑战性。在这项工作中,提出了来自生物质的糖醇的氢解,以在 Ru-Mo/CMK-3 催化剂上有效地合成高级醇。山梨糖醇中的 CC 和 CO 键正断裂形成 C2+ 醇,而 CO 键过度断裂形成 C1-C6 烷烃的现象得到有效抑制。实验结果表明,在连续流动反应器中,产物中C2+醇的收率达到49.0%,C5+醇的收率达到29.9%。初步实验结果和催化剂表征支持 Ru 和 Mo 物种的协同作用,
