Investigation of separation properties of membrane materials based on polyphenylene oxide or diphthalic anhydride and diamine for biogas separation processes
Summary: Decarbonization, minimizing greenhouse gas emissions, circular economy and the waste-to-energy trend lead to increased demand for gas and green energy. The European Biogas Association shows that biomethane gas can cover 30-40% of EU gas demand...
Cu catalyst usage in a hydrogen production in the methanol decomposition process
Abstract: The studies of Cu catalyst usage in a hydrogen production in the methanol decomposition process were performed. CuZnZr-based catalysts with Ga, Cr and Ce additives and CuZnAl-based ones promoted by Zr were investigated. The highest hydrogen...
Transport of Carbon Dioxide, Methane, Oxygen and Nitrogen in a Glassy Polyimide Membrane
Biomethane is one of the controllable Renewable Energy Sources. It may be derived from biogas, a multicomponent gas mixture, using, among others, membrane processes. The proper optimization of such a process requires the knowledge of the phenomena accompanying...
Produkcja wodoru w procesie parowego reformingu etanolu w obecności katalizatorów Cu/Zr/Ga i Cu/Zr/La
Cu/Zr catalysts with about 4% by mass Ga or La addn. were prepared and tested in a continuous flow fixed-bed reactor, in the temp. range of 433–573 K, with an initial molar ratio of ethanol to water of 1:3. The properties of obtained catalysts...
Experimental Study on Direct and Indirect Carbonation of Fly Ash from Fluidized Bed Combustion of Lignite
The research problem was to determine the possibility of aqueous mineral carbonation using fly ash from lignite fluidized bed combustion. Both direct and indirect routes were used. The innovative nature of the research consisted of conducting experiments...
Wyznaczenie kinetyki estryfikacji kwasu laurynowego n-heksanolem, n-oktanolem i n-dekanolem w obecności żywicy jonowymiennej Dowex 50WX8 jako katalizatora
CH3 (CH2 ) 10COOH was esterified with CH3 (CH2 ) 5 OH, CH3 (CH2 ) 7 OH and CH3 (CH2 ) 9 OH at 393–413 K and at molar ratios (alc.:acid) of 3:1–10:1 in the presence of the Dowex catalyst 50WX8 (1.5% by mass). The kinetics of the studied processes...
Zastosowanie fotokatalizy w syntezie metanolu z metanu
A review, with 56 refs., of research progress on the prodn. of MeOH from MeH using oxide photocatalysts: W, Ti, Bi, Zn, Mo, Ni, Ce and Ga, as well as zeolites and graphene C nitrides. The process conditions were presented, in particular the light sources...
Cu/Zn/Zr/Ga Catalyst for Utilisation of Carbon Dioxide to Methanol—Kinetic Equations
This paper presents the kinetics of methanol synthesis from carbon dioxide and hydrogen over a Cu/Zn/Zr/Ga catalyst. Kinetic studies were carried out in a continuous-flow fixed-bed reactor in a temperature range from 433 to 513 K, pressures from 3 to...
Kinetics of esterification of the levulinic acid with n ‐hexanol, n ‐octanol, and 2‐ethylhexanol in the presence of methanesulfonic acid as a catalyst under nonisothermal conditions
The levulinic acid was esterified with alcohol at an alcohol to acid molar ratio of 3:1, 5:1, and 10:1 in the presence of a 0.1 wt% methanesulfonic acid catalyst. During esterification, the temperature was changed linearly from 373 to 428 K and its average...
Copper Tricomponent Catalysts Application for Hydrogen Production from Ethanol
The application of copper-based catalysts in the production of pure hydrogen in the steam reforming of ethanol was performed. The tricomponent Cu/Zr catalysts with about 4 mass% addition of nickel, cobalt, or cerium have been prepared in our laboratory....
