A hybrid catalyst is synthesized using ruthenium nanoparticles deposited on a nanospherical mesoporous polymer. Catalytic properties are studied in guaiacol hydrogenation at a temperature of 200–250°С and a hydrogen pressure of 5.0 MPa. Effect of solvent and catalytic additives on the reaction is investigated. It is shown that the synthesized catalyst exhibits the highest activity in guaiacol hydrodeoxygenation in the two-phase system water/ n -dodecane and when the reaction is carried out in the presence of scandium triflate.

Bimetallic sulfide hydrodearomatization–hydrodesulfurization catalysts based on mesoporous organic supports made of phenol-formaldehyde resins (MPF) and porous aromatic frameworks (PAFs) have been synthesized. The catalysts exhibit high activity in the hydroconversion of light cycle oil: the sulfur content decreases from 3500 to 390 ppm within 8 h of reaction at a hydrogen pressure of 5 MPa and a temperature of 380°C.

Nickel–molybdenum sulfide catalysts have been synthesized in situ in a hydrocarbon medium by the decomposition of the [( n -Bu) 4 N] 2 Ni(MoS 4 ) 2 precursor complex supported on an ordered mesoporous phenol–formaldehyde polymer in the presence of a sulfiding agent (dimethyl disulfide). The catalytic properties of the samples have been studied in a batch reactor at 380°C and a hydrogen pressure of 5.0 MPa using the example of naphthalene, 1-methylnaphthalene, and 2-methylnaphthalene. The tests have shown that the conversion of biaromatic substrates is close to quantitative and the use of dimethyl disulfide as a sulfiding agent leads to an increase in the amount of complete hydrogenation products, as evidenced by the high content of the active phase in this case.
