Title
(EN) CATALYSTS FOR CONVERTING CARBON DIOXIDE AND METHANE TO SYNTHESIS GAS
(FR) CATALYSEURS POUR CONVERTIR DU DIOXYDE DE CARBONE ET DU MÉTHANE EN GAZ DE SYNTHÈSE
Abstract
(EN)
Catalysts for converting carbon dioxide and methane to synthesis gas include an alumina supported copper-nickel alloy composition having the formula NixCuy. The catalyst comprises about 70% to about 98% by weight of alumina in the catalyst, wherein x is an atomic percentage nickel content and y is an atomic percentage copper content, and wherein a ratio of x to y is about 3:1 to about 10:1. In one embodiment, the Ni-Cu catalyst composition according to the present disclosure is derived by state of the art electronic structure calculations based on Density Functional Theory (DFT).

Des catalyseurs pour convertir du dioxyde de carbone et du méthane en gaz de synthèse comprennent une composition d'alliage cuivre-nickel supportée par de l'alumine répondant à la formule NixCuy. Le catalyseur comprend d'environ 70 % à environ 98 % en poids d'alumine dans le catalyseur, x étant un pourcentage atomique de nickel et y étant un pourcentage atomique de cuivre, et un rapport de x à y étant d'environ 3:1 à environ 10:1. Dans un mode de réalisation, la composition de catalyseur Ni-Cu selon la présente invention est dérivée des calculs de structure électronique de l'état de la technique sur la base de la théorie fonctionnelle de densité (DFT).
