BIOETHANOL TRANSFORMATION INTO FUEL RANGE HYDROCARBONS OVER METHAL MODIFIED H-ZSM-5 ZEOLITE

(STEF92 Technology, 2021-12-20, Valentin Yu. Doluda, N. Lakina, R. Brovko, Lev Mushinsky)

Global trend to renewable and green energy application instead of fossil fuel results in grows of bioethanol production and its application in transport and industry. Typically, bioethanol can be used as motor fuel purely and in blends with hydrocarbons, however bioethanol fuel containing less energy compared to traditional gasoline. A possible solution to this disadvantage can be catalytic transformation of bioethanol into hydrocarbons. Bioethanol can be transformed into hydrocarbons over different zeolites inclu...

MEMBRANE ASSISTED HYDROGEN SYNTHESIS FROM BIOETHANOL

(STEF92 Technology, 2021-12-20, N. Lakina, S. Mikhailov, Ksenia Salnikova, Valentin Yu. Doluda)

Considerable effort of scientific community was made in order to substitute traditional energy resources for green and renewable one. One of possible solution of this issue is wide hydrogen application for energy production. Hydrogen can be produced by different ways including water electrolysis, hydrocarbons and alcohols steam reforming, however, in last case hydrogen purification is needed. Membrane hydrogen separation can serve as good alternative compared to rectification or adsorption process. Beside combinat...

METAL MODIFIED MFI MEMBRANES FOR HYDROGEN PURIFICATION

(STEF92 Technology, 2021-12-20, N. Lakina, R. Brovko, Маргарита Александровна Монжаренко, Valentin Yu. Doluda)

Green energy from solar, wind, and water in the nearest future will make a maximum contribution to global energy balance, substituting combustion technologies for energy production. However, considerable efforts need to be made in this direction, therefore, carbon dioxide caption technologies and hydrogen purification technologies are needed for a transition period to reduce the burden on nature. Hydrogen can be considered a green energy source. It can be obtained from water using electrolysis or hydrocarbons, alc...

METHANOL TO HYDROCARBONS TRANSFORMATION PROCESS USING MICROSTRUCTURED MONOLYTH CATALYST

(STEF92 Technology, 2021-12-20, N. Lakina, Valentin Yu. Doluda, R. Brovko, Lev Mushinskiy)

Renewable and waste resources valorization can considerably improve the ecological issues of modern industry and transport sectors of economy. Methanol to hydrocarbon reaction process can be considered one of the possible ways for biomass valorization, resulting in hydrocarbons formation applicable to the chemical industry and transport applications. This way includes biomass gasification process to form a syn-gas, the next step typically includes syn-gas transformation into methanol and the last one includes meth...

At the present stage of development of the biotechnological industry, the most promising objects are enzymes of the oxidoreductase class, which are capable of catalyzing redox processes. One of the most studied enzymes of this class is horseradish root peroxidase. Its immobilization on various carriers allows the biocatalyst to be reused in various technological processes. In recent years, magnetic nanoparticles have been increasingly used as effective carriers of enzymes.In this work, we study the oxidation of 2,...

N-METHYL-D-GLUCOSE AMINE SYNTHESIS OVER NI BASED CATALYSTS

(STEF92 Technology, 2020-09-20, Степан Петрович Михайлов, Mikhail G. Sulman, Valentina G. Matveeva, А. И. Сидоров, Valentin Yu. Doluda)

N-methyl-D-glucose amine is an amine formed by reduction of glucosylamine or glucose oxime. N-alkylated glucamines are prepared from D-glucose and relevant alkylamines. Here synthesis of N-methyl-D-glucose amine by consecutive condensation of D-glucose with methylamine in ethanol media followed by reduction over Ni containing hyper crosslinked polystyrene is reported. In typical synthesis 50 g sample of D-glucose monohydrate was added to 150 ml of ethanol (96 wt.%) and stirred under 600 rpm for 30 minutes. Suspens...
