Manganese and nickel co-modified K/Co/MoS₂ catalysts supported on graphene were prepared by incipient wetness impregnation method for application in higher alcohol synthesis (HAS). All catalysts were characterized by X-ray diffraction (XRD), nitrogen adsorptiondesorption, temperature-programmed reduction (TPR) and transmission electron microscopy (TEM). The effect of promoters, as well as supports on higher alcohol synthesis production from syngas, was investigated in a fixed bed reactor. The process was performed with an molar ratio H₂ : CO = 1 : 1, operating pressure and temperature of 4 MPa and 330 °C, respectively, and gas hourly space velocity (GHSV) 3.84 m³ (STP)/(kg_cat.·h) as reaction conditions (STP – standard temperature and pressure). Results originated from practical works showed that the addition of Ni to the graphene-based catalyst increased HAS production and decreased methanol formation. The total alcohols space-time yield (STY) and alcohol selectivity on Ni/Mn/Co/Mo/K/graphene catalyst reached a maximum at 0.41 g_alc./(g_cat.·h) and 63.51 %, respectively, which is higher than the same composition over alumina supported catalyst.

Cu- and Fe-containing catalysts were studied in the reaction of selective hydrogenation of furfural to furfuryl alcohol (FA). The catalysts were prepared by fusing the metal nitrates and reduced in situ at 250 °C in the reactor before the reaction. A batch reactor was used for the process at 150 °C and 6.0 MPa of hydrogen. The highest activity was shown to be characteristic of the Cu₂₀Fe₆₆Al₁₄ catalyst that provided 96 % conversion of furfural and 97 mol.% selectivity to FA. In the flow system, the furfural conversion reached 100 % and the selectivity to FA up to 95 mol.% at 160 °C and 5 MPa of hydrogen. The developed catalyst remained highly active during its continuous operation for 30 hours. The observed high activity was accounted for by the presence of stabilized disperse copper particles in the copper-iron containing catalyst.

The influence of concentrations of the monomer, triethylaluminum, and hydrogen on the molecular mass of polyhexene obtained by polymerization of hexene-1 over a supported titanium-magnesium catalyst was studied. Ratios of rate constants of the transfer of polymer chain with the monomer, triethylaluminum (AlEt₃) and hydrogen to the rate constant of the chain-growth were calculated.

The data obtained allowed the contribution of individual reactions of chain transfer to molecular mass of the polymer to be estimated at various polymerization conditions and the polymerization conditions to be chosen deliberately in order to synthesize polyhexene with the required molecular mass. The discovered inhomogeneity of the centers active to the chain transfer with hydrogen in the presence of the AlEt₃ co-catalyst caused changes in the polymer polydispersion upon changes in the hydrogen concentration in the reaction medium. Curves of the polyhexene molecular mass distribution in polyhexene samples with different polydispersion were analyzed using their resolution into Flory components.

Studies of the influence of acidity of alumina supports on properties of supported palladium particles were aimed at improving the activity of catalysts for hydrogenation of unsaturated hydrocarbons of pyrolysis gasoline fraction. High-disperse palladium particles demonstrate the high catalytic activity but their electron deficiency make them suffering from blocking with unsaturated hydrocarbons. NH₃ TPR, TEM and XPS techniques were used for studying aluminopalladium catalysts; different acidities of the catalyst supports resulted from their chemical modification with various agents. The catalysts were tested for lab-scale hydrogenation of butadiene-1,3. Against the non-modified samples, the catalysts supported on modified alumina provided a lower conversion of butadiene-1,3 but a higher selectivity to butene-1. A higher conversion of butadiene-1,3 at the preserved selectivity to butene-1 and butane was observed in the presence of the catalyst supported on base-modified alumina.

The work was aimed at studying the behavior of the two-phase gas-liquid flow at the inlet pipe of a catalytic reactor. Apart from the classical approach using literature flow diagrams, methods of computational hydrodynamics were used for 3D simulation of the space propagation of phases in the pipeline. The results obtained demonstrated non-uniform distribution of the liquid phase through the outlet section of the pipeline and the time-unsteady mass consumption of the liquid phase. The maximal peak consumptions were ca. 3 times as high as the average values. With the data on the flow diagrams, the CFD simulation demonstrated that variations in the gas consumption within the range under study do not cause changes in the behavior of the two-phase flow but an increase in the gas consumption results in smoothening of the non-uniform distribution of the liquid phase at the outlet pipe. The data on the flow behavior are necessary for designing catalytic reactors to provide uniform propagation of the two-phase flow over the catalyst bed, for example, hydrotreatment reactors used in refineries.

Alumina-based spherical granules were prepared by disk granulation. Products of gibbsite thermoactivation in various reactors were used as the initial materials. In the course of molding, combustible additives (starch, carbon, wood meal) were added to the thermoactivated gibbsite powder, and NaOH (10 %), C₂H₅OH (15 %), Н₃ВО₃ (6 %) to the wetting solution (H₂O). With the product of centrifugal thermoactivation of hydrargillite, the prepared granules were stronger at the larger average size of pores; addition of NaOH, C₂H₅OH and H₃BO₃ led to an increase in the specific surface area and micropore proportion but had different effects on the mechanical strength of the granules. Introduction of combustible additives (wood meal, activated carbon) affected only slightly the specific surface area, favored an increase in the total pore volume and mesopore volume, resulted in a decrease in bulk density and mechanical strength of the granules. Conditions were determined for preparation of a highly effective strong dessicant with large specific surface area (up to 340 m²/g) and average pore diameter up to 3.4 nm. Conditions were determined for preparation of strong ultramacroporous granules that are highly active to the Klaus process.

The performance of the Russian catalyst for steam conversion of hydrocarbons was monitored. The catalyst was produced at the Angarsk Plant for Catalysts and Organic Synthesis and operated in a hydrogen generation unit at the Syzran Refinery. The Russian catalyst was compared to the imported analog under the Rosneft program of import substitution. It was demonstrated under industrial conditions that the Russian catalyst is comparable in quality with the world standards.

The influence of the factors such as the medium composition, temperature, pH and illumination intensity on the lipid accumulation, composition and metabolism of microalgae biomass is estimated. It is shown that wastewater exhibits most promise among the substrates used for microalgae cultivation. Approaches to synthesis of biodiesel fuel from microalgae lipids based on biocatalytic transesterification with various lipases are considered.
