Abstract
A method for preparing a mixture (M) comprising at least an alcohol (Aj), said method comprising the following steps: i) a step in which at least an alcohol (Ai) in gaseous state is oligomerized, thereby producing a mixture (A); ii) a step in which the mixture (A) is condensed to a gaseous stream and to a liquid stream corresponding to a condensed mixture (A); and iii) a step in which the condensed mixture (A) is hydrogenated in the liquid state.
Claims20
A process for the preparation of a mixture (M) comprising at least one alcohol (Aj), said process comprising the following stages:
- i) a stage of oligomerization of at least one alcohol (Ai) in gas phase, resulting in a mixture (A);
- ii) a stage of condensation of said mixture (A), resulting in a gas stream and in a liquid stream corresponding to a condensed mixture (A);
- and
- iii) a stage of liquid-phase hydrogenation of said condensed mixture (A) to obtain said mixture (M) comprising at least one alcohol (Aj).
