This invention relates to a new process to directly produce transportation gasoline from synthesis gas containing principally carbon monoxide, carbon dioxide, and hydrogen. The process entails three sequential catalytic stages with intermediate heat exchange to provide the requisite temperature in each stage, but with no interstage separation. The recycle loop enhances the conversion of the synthesis gas to the desired products and also serves as heat sink for the highly exothermic reactions involved in each stage. La présente invention concerne un nouveau procédé de production directe d'essence pour les transports à partir de gaz de synthèse contenant principalement du monoxyde de carbone, du dioxyde de carbone, et de l'hydrogène. Le procédé consiste en trois étapes catalytiques séquentiels avec un échange thermique intermédiaire pour fournir la température requise dans chaque étape, mais sans séparation entre les étapes. La boucle de recyclage améliore la conversion du gaz de synthèse en produits souhaités et sert également de dissipateur thermique pour les réactions fortement exothermiques impliquées dans chaque étape.
