PD-CONTAINING CATALYSTS IN FATTY ALCOHOLS PRODUCTION

(STEF92 Technology, 2017-06-20, Esther Sulman)

Show more

Among different methods of oil-crop biomass processing two main reactions are allocated пїЅ oil transesterification with methanol and fatty acid deoxygenation. Last decades there is a growing researcherпїЅs interest to the production of fatty alcohols with carbon number 10-18 by selective hydrogenation of carboxylic group of fatty acids. These alcohols can be used in various fields, e.g. pharmaceutical, cosmetic, fine organic synthesis as well as in biofuel industries. In this work, we propose to use polymeric cat...

THE KINETIC RESEARCH OF CELLULOSE CONVERSION TO POLYOLS

(STEF92 Technology, 2017-06-20, Esther Sulman)

Show more

This work is aimed at studying of the kinetics of the cellulose hydrolytic hydrogenation process. In the course of the study, the methodology of the process in a high-pressure reactor under subcritical water conditions in the presence of the optimal synthesised catalyst, 3% Ru based on hypercrosslinked polystyrene MN 270 (Purolite Ltd, UK) (3% Ru/MN 270) was developed. The optimal parameters of the cellulose hydrolytic hydrogenation process were selected: the temperature пїЅ 205 пїЅC, the hydrogen partial pressure...

THE STUDY OF SOLUBILITY OF CARBON MONOOXIDE AND HYDROGEN IN PROPANOL-2 FOR METHANOL LIQUID-PHASE SYNTHESIS

(STEF92 Technology, 2017-06-20, Esther Sulman)

Show more

The solubility of gases in liquid is an important parameter required for the interpretation of rate data in gas-liquid, gas-liquid-liquid and gas-liquid-solid reactions. Gas-liquid mass transfer plays an important role in many industrial processes, e.g. methanol synthesis. The overall rate of gas-phase and gas-liquid phase reactions strongly depends on mass transfer. A large number of solubility data of hydrogen and carbon monoxide in a variety of solvents is available in the literature, but the data on the gas so...

THE USE OF RU/MN 100 FOR MONOSACCHARIDE HYDROGENATION

(STEF92 Technology, 2017-06-20, Esther Sulman, Maxim Grigore, Galina Demidenko, Irina Shkileva, Valentina Matveeva)

Show more

Monosaccharides, as well as the other carbohydrates, are used for the production of different chemicals including polyols which are widely used in food, medical, pharmaceutical industries. A large number of catalysts can be applied for these purposes but the main problem of numerous catalysts is instability leading to a high-speed deactivation, active phase leaching and support destruction. So the development of highly active, mechanically and chemically stable catalysts is one of the main tasks for the researcher...
