Abstract

The disclosure describes a process for methanol synthesis remarkable in that it comprises the steps of (a) providing syngas (3), (b) providing at least one first catalytic composition (9) comprising at least one first methanol synthesis catalyst; (c) putting into contact said syngas (3) with said first catalytic composition (9) under first temperature conditions, to provide a first gaseous effluent (15); (d) providing at least one second catalytic composition (17) comprising at least one second methanol synthesis catalyst; (e) putting into contact at least a part of said first gaseous effluent (15) with said second catalytic composition (17), to provide a second gaseous effluent (23) and a second liquid effluent (21); (f) recovering methanol from first (15) and/or second (23) gaseous effluent. The use of a first catalytic composition (9) that comprises at least one first methanol synthesis catalyst in such a process for methanol synthesis is also described.
