    Opis:
    A group of supported ruthenium catalysts was prepared and tested in methanation of small CO amounts (7000 ppm) in hydrogen-rich streams. High surface area graphitized carbon (484 m2/g) was used as a support for ruthenium and RuCl3 was used as a Ru precursor. Some of the Ru/C systems were additionally doped with barium (Ba(NO3)2 was barium precursor). The catalysts were characterized by the chemisorption technique using CO as an adsorbate. To determine the resistance of the catalysts to undesired carbon support methanation, the TG-MS experiments were performed. They revealed that the barium addition inhibits support losses. The studies of CO methanation (fl ow reactor, atmospheric pressure) have shown that some of the supported ruthenium catalysts exhibit high activities referred to the metal mass. The catalytic properties of ruthenium proved to be dependent on metal dispersion. Some of the Ru/C and Ba-Ru/C systems exhibit higher activity in CO hydrogenation than the commercial nickel-based catalyst.

    Opis:
    Ni-Al2O3 catalysts prepared by solution combustion method for syngas methanation were enhanced by employing various heating rate and different solvent. The catalytic properties were tested in syngas methanation. The result indicates that both of heating rate and solvent remarkably affect Ni particle size, which is a key factor to the catalytic activity of Ni-Al2O3 catalysts for syngas methanation. Moreover, the relationship between Ni particle size and the production rate of methane per unit mass was correlated. The optimal Ni-Al2O3 catalyst prepared in ethanol at 2°C/min, achieves a maximum production rate of methane at the mean size of 20.8 nm.

    Opis:
    Within the Waste2Fuel project, innovative, high-performance, and cost-effective fuel production methods are developed to target the “closed carbon cycle”. The catalysts supported on different metal oxides were characterized by XRD, XPS, Raman, UV-Vis, temperature-programmed techniques; then, they were tested in CO2 hydrogenation at 1 bar. Moreover, the V2O5 promotion was studied for Ni/Al2O3 catalyst. The precisely designed hydrotalcite-derived catalyst and vanadia-promoted Ni-catalysts deliver exceptional conversions for the studied processes, presenting high durability and selectivity, outperforming the best-known catalysts. The equilibrium conversion was reached at temperatures around 623 K, with the primary product of reaction CH4 (>97% CH4 yield). Although the Ni loading in hydrotalcite-derived NiWP is lower by more than 40%, compared to reference NiR catalyst and available commercial samples, the activity increases for this sample, reaching almost equilibrium values (GHSV = 1.2 × 104 h–1, 1 atm, and 293 K).

    Opis:
    The primary aim of the publication is to show the possibility of the synthesis of palladium nanoparticles directly on the nickel molecular mesh. A combination of chemical and physicochemical methods was used. Design/methodology/approach Palladium chloride was chosen as the precursor of palladium nanoparticles, dissolved in alcohol, water or a mixture thereof. Surface topography studies of the prepared nanoparticles were made using a scanning electron microscope, Supra 35 (Zeiss’s company), and transmission electron microscope S/TEM TITAN 80-300 (FEI company). Qualitative studies were performed using spectroscopy of scattered X-ray energy using the Energy Dispersive Spectrometer to define the chemical composition of prepared nanocatalysts. The chemical states of the elements were analysed using X-ray photoelectron spectroscopy. Nanocatalyst structures were identified using X-ray crystallography. Findings Using such methods proved that the obtained material is Pd-Ni synthesised using a mixture of alcohol and water assisted by ultrasound. Nanoparticles with oval shapes and diameters below 10 nm were obtained. Research limitations/implications During the tests, it was decided to abandon the use of the ascorbic acid reducer, which, combined with the temperature, had a negative impact on the nickel substrate. Practical implications Nanocatalyst has been achieving a gradually increasing interest from researchers in environmental areas. The developed materials can be used in low-temperature carbon dioxide methanation. Originality/value The results provide a novel road for designing and developing efficient, low-cost, and low-temperature double metallic catalysts.

    Opis:
    The presentation is meant to give a short overview on the state of the development of biogas technologies with special emphasis on the situation in Germany. Although the share of biogas based electrical energy among other types of renewable energies has become smaller, it still plays an important role for the compensation of fluctuating alternative energies and for the recycling of important substances like fertilisers as well. The growth of biogas capacities is limited due to the limited abundance of substrates. But newer technologies allow the biochemical production of biogas from carbon dioxide and hydrogen without any organic matter. Most probably, such processes will have the potential to change the common practise of biogas upgrading at least.

    Opis:
    Extrapolation of world energy consumption from 1990 to 2010 indicates the complete exhaustion of world reserves of oil, natural gas, uranium and coal by 2040, 2043, 2046 and 2053, respectively. For the survival of all people in the whole world, intermittent and fluctuating electricity generated from renewable energy should be supplied in the form of usable fuel to all people in the whole world. We have been working on research and development of global carbon dioxide recycling for the use of renewable energy in the form of methane via electrolytic hydrogen generation using carbon dioxide as the feedstock. We created energy-saving cathodes for hydrogen production, anodes for oxygen evolution without chlorine formation in seawater electrolysis, and catalysts for methanation of carbon dioxide and built pilot plants of industrial scale. Recent advances in materials are described. Industrial applications are in progress.
    Ekstrapolacja światowego zużycia energii z lat 1990-2010 wskazuje, że całkowite wyczerpanie światowych zasobów ropy naftowej nastąpi w 2040 roku, gazu ziemnego w 2043 roku, uranu w 2046 roku a węgla w 2053 roku. Dla przetrwania ludzkości na całym świecie energia elektryczna powinna być generowana z odnawialnego zródła w formie paliwa dostępnego dla kazdego. Opracowano technologie globalnego recyklingu dwutlenku wegla i zastosowania metanu jako formy odnawialnej energii generowanej poprzez uwodornienie CO2 wodorem produkowanym podczas elektrolizy wody morskiej. Opracowano energooszczedne katody do produkcji wodoru, anody do produkcji tlenu bez towarzyszącej temu emisji gazowego chloru podczas elektrolizy wody morskiej oraz katalizatory stosowane w procesie uwodornienia dwutlenku węgla. Wybudowano również pilotażowa instalacje w skali przemysłowej. Praca opisuje ostatnie postępy w industrializacji procesu.

    Opis:
    The photocatalytic reduction of carbon dioxide with hydrogen was studied by Temperature-Programmed Surface Reaction (TPSR). This process was carried out in a flow reactor that was especially designed and constructed for this purpose. Titanium dioxide (TiO2, Degussa P-25) was used as supports for platinum, ruthenium and nickel catalysts. The experimental results indicated that the activity of photoreduction of CO2 changes as follows: Ru/TiO2> Ni/TiO2>= Pt/TiO2> TiO2.
