Method for preparing hydrogenated rosin through rosin hydrogenation and catalyst thereof

The invention belongs to the technical field of hydrogenated rosin preparation, and discloses a method for preparing hydrogenated rosin through rosin hydrogenation and a catalyst thereof. According to the invention, nickel particles are loaded on amphiphilic mesoporous nanoparticles through a nickel salt reduction hydrogenation principle, and tungsten and boron elements are introduced to form the ternary amorphous alloy nanoparticle sphere catalyst Ni-W-B/CxNy (at) mSiO2 with a catalytic property. Boron atoms in the catalyst Ni-W-B/CxNy (at) mSiO2 can immobilize more active Ni nanoparticles, and more weak acid centers can be brought to a catalytic system by adding a tungsten element; due to the addition of boron and tungsten, agglomeration of single nickel nanoparticles can be prevented to a great extent, so that the catalyst has good stability, and the service life of the catalyst is prolonged; and the reaction temperature of the whole rosin hydrogenation reaction is milder. 本发明属于氢化松香制备技术领域，公开了一种松香加氢制备氢化松香的方
