Abstract In an embodiment, a process of making C2+ hydrocarbons comprises contacting a feed comprising a methane steam reforming gas and an additional carbon dioxide with a manganese oxide-copper oxide catalyst to produce a product syngas in a contacting zone under isothermal conditions at a temperature of 620 to 650°C; and converting the product syngas to C2+ hydrocarbons in the presence of a Fischer-Tropsch catalyst; wherein the methane steam reforming gas has an initial H2:CO volume ratio greater than 3; wherein the product syngas has a H2:CO volume ratio of 1.5 to 3; and wherein the contacting further comprises removing water. Dans un mode de réalisation, un procédé de fabrication d'hydrocarbures C2+ consiste à mettre en contact une charge d'alimentation comprenant un gaz de reformage de vapeur de méthane et un dioxyde de carbone additionnel avec un catalyseur oxyde de manganèse-oxyde de cuivre afin de produire un produit gaz de synthèse dans une zone de contact dans des conditions isothermes à une température de 620 à 650 °C et à convertir le produit gaz de synthèse en hydrocarbures C2+ en présence d'un catalyseur de Fischer-Tropsch ; le gaz de reformage de vapeur de méthane ayant un rapport volumique H2:CO initial supérieur à 3 ; le produit gaz de synthèse H2:CO ayant un rapport volumique de 1,5 à 3 ; et la mise en contact comprenant en outre l'élimination de l'eau.
