Abstract

Un processus de préparation d'hydrocarbures en C2 à C4 comprend l'introduction d'un flux d'alimentation comprenant de l'hydrogène gazeux et un gaz contenant du carbone choisi dans le groupe constitué par le monoxyde de carbone, dioxyde de carbone, et des mélanges de ceux-ci dans une zone de réaction d'un réacteur, et la conversion du courant d'alimentation en un courant de produit comprenant des hydrocarbures en C2 à C4 dans la zone de réaction en présence d'un catalyseur hybride formé. Le catalyseur hybride formé comprend un composant catalyseur d'oxyde métallique comprenant de l'oxyde de gallium et de la zircone, un composant catalyseur microporeux qui est un tamis moléculaire ayant des ouvertures de pore de 8-MR (cycle de chaînons), et un liant comprenant de l'alumine, le liant d'alumine étant préparé sous la forme d'une solution colloïdale, d'une suspension ou d'un gel par peptisation d'un précurseur de liant comprenant des oxydes ou des hydroxydes d'aluminium avec une solution d'acide carboxylique organique.
