Abstract
A plant complex may include a unit that produces CO2-containing gases, a gas conducting system for CO2-containing gases, a gas/liquid separation system, a reformer that is connected to the gas conducting system and where the CO2-containing gas reacts with H2 and/or hydrocarbons to give a CO— and H2-containing synthesis gas mixture. The reformer is connected to a reactor for producing higher alcohols in which the synthesis gas mixture reacts with H2 to give a gas/liquid mixture containing higher alcohols. For separating off the alcohols of the gas/liquid mixture, the gas/liquid separation system is connected to the reactor for producing higher alcohols.

A plant complex comprising:
- a unit that produces CO2-containing gases;
- a gas conducting system for CO2-containing gases;
- a gas/liquid separation system;
- and
- a reformer that is connected to the gas conducting system, wherein the reformer is configured so that the CO2-containing gases react with H2 and/or hydrocarbons in the reformer to give a CO— and H2-containing synthesis gas mixture, the reformer being connected to a reactor for producing higher alcohols in which the synthesis gas mixture reacts with H2 to give a gas/liquid mixture containing higher alcohols,
- wherein for separating off the alcohols of the gas/liquid mixture, the gas/liquid separation system is connected to the reactor for producing higher alcohols.
A process for producing higher alcohols from CO2-containing gases with a plant complex comprising a unit that produces CO2-containing gases, a gas conducting system for CO2-containing gases, a reformer, a reactor for producing higher alcohols, and a gas/liquid separation system, wherein the process comprises:
- V1) reacting hydrocarbons with the CO2-containing gases and/or CO2 and/or O2 and/or H2O as oxygen sources to give a CO— and H2-containing synthesis gas mixture in the reformer;
- V2) reacting the synthesis gas mixture with H2 to give a gas/liquid mixture containing higher alcohols in the reactor for producing higher alcohols;
- and
- V3) separating off liquid alcohols of the gas/liquid mixture in the gas/liquid separation system from gas components.
