CA 2546181

A process for the preparation of urea comprising adding methanol to a carbon monoxide containing gas, contacting the carbon monoxide-containing gas, methanol and water in at least one shift step in the presence of a catalyst comprising copper, zinc and aluminium and/or chromium to produce a stream rich in carbon dioxide, transferring the carbon dioxide-rich stream from the at least one shift step to a urea reactor and reacting the carbon dioxide with ammonia to produce urea.

L'invention concerne un procédé de préparation d'urée consistant à ajouter du méthanol à un gaz contenant du monoxyde de carbone, à mettre en contact le gaz contenant du monoxyde de carbone, du méthanol et de l'eau dans au moins un étage de conversion catalytique, en présence d'un catalyseur contenant du cuivre, du zinc et de l'aluminium et/ou du chrome afin de produire un flux riche en dioxyde de carbone, à transférer ce flux riche en dioxyde de carbone du/des étages de conversion catalytique à un réacteur d'urée, et à faire réagir le dioxyde de carbone avec de l'ammoniac afin de produire de l'urée.
