In this work, the synthesis method of magnetically recoverable catalyst (3 % Ru-Fe3O4/HPS MN270) was developed. Synthesized magnetically recoverable supports and catalysts were characterized by different physical-chemical methods. The magnetic properties of the catalyst samples were studied. The experimental samples were shown to have a high saturation magnetization (4.0 ± 0.5 emu/g). The magnetization curves no remanence or coercivity is observed, demonstrating superparamagnetic behavior which is characterized for magnetite. A high value of saturation magnetization allows for fast magnetic separation of the 3 % Ru-Fe3O4/HPS MN270 particles. The use of this catalyst in the process of microcrystalline cellulose hydrogenolysis in subcritical water at 255 °?, 60 bar hydrogen pressure in 50 minutes allows PG and EG selectivities of 20.0 and 22.6%, respectively, at 100% of cellulose conversion. The catalyst is stable under hydrothermal conditions of the process; it is easily separated from the liquid phase with the external magnetic field and can be reused. Therefore, the results of the research prove the advantages of the use of magnetically retrievable catalysts in biomass processing into chemicals.
