The reductive catalytic fractionation of flax shives in the presence of bimetallic NiRu catalysts supported on oxidized carbon materials (CM) such as mesoporous Sibunit and carbon mesostructured by KAIST (CMK-3) was studied. The catalysts based on CMK-3 were characterized by a higher surface area (1216 m/g) compared to the ones based on Sibunit (315 m/g). The catalyst supported on CMK-3 (10Ni3RuC400) was characterized by a more uniform distribution of Ni particles, in contrast to the Sibunit-based catalyst (10Ni3RuS450), on the surface of which large agglomerated particles (300-400 nm) were presented. The bimetallic catalysts were found to be more selective towards propanol-substituted methoxyphenols compared to monometallic Ru/C and Ni/C catalysts. A high yield of monomers (up to 26 wt%, including 17% 4-propanol guaiacol) was obtained in the presence of a 10Ni3RuC400 catalyst based on CMK-3.
在氧化碳材料（如中孔 Sibunit 和 KAIST 制的碳介孔材料（CMK-3））负载的双金属 NiRu 催化剂存在的条件下，研究了亚麻屑的还原催化分级。与 Sibunit（315 m/g）相比，基于 CMK-3 的催化剂具有更高的表面积（1216 m/g）。与 Sibunit 基催化剂（10Ni3RuS450）相比，负载在 CMK-3 上的催化剂（10Ni3RuC400）表面的 Ni 颗粒分布更均匀，后者表面呈现出大的团聚颗粒（300-400nm）。与单金属 Ru/C 和 Ni/C 催化剂相比，双金属催化剂对丙醇取代的甲氧基苯酚具有更高的选择性。在基于 CMK-3 的 10Ni3RuC400 催化剂的存在下，可获得高达 26wt%的单体（包括 17%的 4-丙醇愈创木酚）。
