A kutatás összefoglalója, célkitűzései szakemberek számára
Itt írja le a kutatás fő célkitűzéseit a témában jártas szakember számára.
Catalytic dry reforming of methane is an important, highly endothermic route to CO rich synthesis gas.
Because carbon formation is thermodynamically favored under all conditions, the reaction can only be
stabilized by kinetic control. We propose a collaborative study of laboratories at the Institute of Isotopes of
the Hungarian Academy of Sciences (IoI), the Technische Universität Wien (TUW) and the Technische Universität München (TUM) to elucidate and understand the elementary reactions of methane reforming
with CO2 on supported Pt and Ni catalysts (modified with Au) under a wide variety of reaction conditions
and to use this knowledge in the quest for a new generation of highly active and stable catalysts. UHV model studies (TUW) address the specific properties of oxide supports and metal nanoparticles via surface science methods, focusing on the nature of interaction and reaction with reactants and products. Novel robust and stable nanostructured catalysts will be synthesized using traditional and sol-based approach (IoI) and are expected to facilitate a successful transition from noble to base metals. The kinetic and spectroscopic characterization (TUM) of dispersed catalysts will provide the necessary quantitative information on the dispersed catalysts at the main stages of preparation and reaction.The kinetic evaluation under stationary and transient conditions will provide a rigorous kinetic model to explain catalytic behavior and give feedback to catalyst synthesis.

Mi a kutatás alapkérdése?
Ebben a részben írja le röviden, hogy mi a kutatás segítségével megválaszolni kívánt probléma, mi a kutatás kiinduló hipotézise, milyen kérdéseket válaszolnak meg a kísérletek.
The most significant problem is that under nearly all reaction conditions, carbon is thermodynamically stable and its formation can lead even to a the blockage of the reactor. In consequence, the (catalyzed) formation of carbon can only be kinetically retarded via adjusting the properties of the catalyst. We propose to explore, (I) how the reactants CH4 and CO2 interact with the metal and the supports and (II) how the primary species react further to generate CO and H2, but also surface carbonaceous species that eventually lead to carbon formation. This will be complemented by studying (III) how the surface carbonaceous species react with varying concentrations of CO2 (and potentially H2O) and (IV) how these carbon species change in morphology and nature growing more refractory with reaction time. Based on the insight into these elementary reactions, we propose to use advanced synthesis techniques to modify catalysts to achieve reduced coke formation and stabilize the catalytic performance. We will use a combination of surface science studies under UHV conditions with model catalysts (TU Vienna), advanced catalyst synthesis and isotope labeling studies, which allow us to trace the importance of the coupled reactions (Institute of Isotopes, Budapest), as well as scalable material preparation of thermally stable catalysts and spectroscopic and kinetic reaction studies up to high pressures (TU München). If successful, we expect to be able to understand
the impact of the individual reactions under the various operating regimes and to experimentally
realize this in the synthesis of catalysts.

Dry reforming of methane (CH4 + CO2 ⇌ 2CO +2H2, ΔHo = 261 kJ/mol) is not only the most endothermic reforming reaction, it leads also to the lowest concentration of hydrogen in synthesis gas. Despite these drawbacks it is an important reaction from the practical side, because of large concentrations of carbon dioxide in some of the natural gas reservoirs and because the H2/CO ratio of one is being used for the synthesis of oxygenates. The other aspect, which makes the reaction very interesting for selected cases, is related to the fact that methane and carbon dioxide are greenhouse gases. While the overall need for synthesis gas with a H2/CO = 1 may be limited, the availability of CO2 and methane at one location may make it economically very attractive to convert both to synthesis gas. As note in passing it should be mentioned that due to the projected size of an industrial implementation, the cost of the catalyst is an important element in the process development. While noble metal catalysts are less susceptible to the accumulation of deactivating carbon during the reaction, their price is prohibitive for industrial implementation at a large scale. Thus, a new generation of supported Pt, Ni catalysts with high activity and stability will be proposed based on the outcome of collaboration.

A kutatás összefoglalója, célkitűzései laikusok számára
Ebben a fejezetben írja le a kutatás fő célkitűzéseit alapműveltséggel rendelkező laikusok számára. Ez az összefoglaló a döntéshozók, a média, illetve az érdeklődők tájékoztatása szempontjából különösen fontos az NKFI Hivatal számára.
In methane dry reforming, greenhouse gases, methane and carbon dioxide are utilized to obtain a valuable feedstock, synthesis gas (CH4 + CO2 ⇌ 2CO +2H2). Synthesis gas is a mixture of hydrogen and carbon monoxide in this case with H2/CO ratio of 1 that is being used for the synthesis of oxygenates. The other economical aspect of dry reforming is that some of the natural gas reservoirs with large concentrations of carbon dioxide (low heating value) or even biogas could be converted. The first and most significant problem associated with dry reforming carried out at high temperature is related to the fact that destructive carbon formation can be significant, leading even to a complete blockage of the reactor. The cost of the catalyst is an important element in the process development. While noble metal catalysts are less susceptible to the growth of undesired carbon that may lead reactor blockage, their price is prohibitive for industrial implementation at a large scale. We aim to retarde the (catalyzed) formation of undesired carbon via adjusting the properties of the catalyst. To achieve this via a knowledge based approach, the relevant reactions and their relation to properties of the catalyst need to be understood at an elementary level. A new generation of supported Pt, Ni catalysts with high activity and stability will be proposed based on the outcome of the research.

A biogáz vagy a nagy CO2 tartalmú földgáz hasznosítására alkalmas kiemelt célreakció a metán száraz reformálása (CH4+CO2⇌2CO+2H2). A katalizátor szeneződésének csökkentését célozva, Ni, Pt és kétfémes NiPt/ZrO2 katalizátorok készültek impregnálással Na-promoter hozzáadásával vagy nélküle, valamint szol-módszerrel. A kutatómunka során sikeresen 1) kifejlesztettünk egy Na2O-dal promoveált Ni katalizátort, mely nemesfém jelenléte nélkül is aktív és stabil volt modell biogáz átalakításában, 2) meghatároztuk az egyes reakciólépeseket jelzett reaktánsok alkalmazásával és 3) feltérképeztük a felületi szén képződési útjait egyes katalizátorrendszerek esetén. A Ni/ZrO2 célzott módosítása mindössze 0.6 tömeg% Na2O-dal jelentősen csökkentette a főként metánból származó dezaktiváló szénféleségek mennyiségét. A tömbi Na2ZrO3 irodalomból ismert magas hőmérsékletű, reverzibilis CO2 abszorpciós kapacitása itt a Ni részecskék nanokörnyezetében érvényesül: a dezaktiváló felületi szén a kiterjedt Na2O-ZrO2-Ni/NiOxHy határfelületen képződő instabil karbonátok dinamikus átalakulása során eltávozik. A nikkelhez 15 at% platinát adva csak az impregnálással de Na2O hozzáadása nélkül készült katalizátornál volt tapasztalható aktvitás növekedés, míg az összes kétfémes mintán több felületi szén rakódott le, mint a megfelelő egyfémes mintákon. Ezt azzal magyarázzuk, hogy a kétfémes részecskékben a Ni teljesen fémes marad a reakció során, így fokozódik a metán teljes disszociációja és a szeneződés.

Dry reforming of methane (CH4+CO2⇌2CO+2H2) is a target reaction possessing major importance in the conversion of CO2-rich natural gas or biogas. In the present project, aiming to decrease the unwanted coke formation during the reaction, impregnation with or without the concomitant addition of sodium promoter and sol-based synthesis methods were applied to prepare Ni, Pt and bimetallic NiPt/ZrO2 catalysts. We successfully accomplished 1) the development Na2O-promoted Ni catalysts highly active and stable in converting a model biogas without the presence of any noble metal, 2) the description of the reaction steps using labeled reactants and 3) the determination of the coke formation routes on each catalyst system. Localized promotion of Ni/ZrO2 with 0.6 wt% Na2O highly depressed the deactivating coke deposition mainly from methane. Thus, we could exploit the reported high temperature reversible CO2 capture ability of Na2ZrO3 at nanoscale, which must play a decisive role in the removal of surface coke at the extended Na2O-ZrO2-Ni/NiOxHy interface via the formation and decomposition of transient carbonates. Alloying Ni with 15%Pt led to significant activity increase only for the catalyst prepared by impregnation without Na2O, while coke deposition increased on all bimetallic samples compared to the monometallic counterparts. We speculate that as NiPt particles are easier to reduce, Ni stays fully metallic and accumulates more carbon from CH4 decomposition during reaction.
