Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Ni‐ and Ru‐containing supported catalysts were prepared and used for the CO₂ hydrogenation to methane (Sabatier reaction) in the gas phase. Tests on the effect of the reaction temperature and pressure were in the focus. ZrO₂ and γ‐Al₂O₃ were used as suitable catalyst supports. CO₂ and H₂ conversions of 70 – 80 % and selectivity to methane of &amp;&amp;num;62; 99 % were reached. TiO₂ and SiO₂ based catalysts exclusively lead to CO and seem to be not suited for this reaction. The investigations on the pressure effect impressively demonstrated the influence on the chemical equilibrium. CO₂ and H₂ can be nearly completely converted with &amp;&amp;num;62; 99.9 % selectivity to methane over Ru/ZrO₂.</p> </abstract>
