Method and installation for producing liquid energy carriers from a solid carbon carrier
First Claim
1. A process for producing a liquid fuel comprising:
- drying a solid carbon carrier in a drying apparatus,producing oxygen and hydrogen in an apparatus for electrolysis of water,supplying said oxygen as a gasification agent to a gasification apparatus and gasifying the carbon carrier in said gasification apparatus to produce a synthesis gas,supplying said hydrogen and said synthesis gas to a synthesis apparatus and synthesizing the liquid fuel in said synthesis apparatus from said synthesis gas, andfeeding at least part of off-vapor from the drying apparatus and at least part of residual gas obtained in the synthesis apparatus to the gasification process in the gasification apparatus.

Abstract
The invention relates to a method and installation for producing liquid energy carriers from a solid carbon carrier by means of gasifying a solid carbon carrier. The installation is at least comprised of a drying device, a gasification apparatus, a synthesizing device for synthesizing the liquid energy carrier, a device for effecting the electrolysis of water for producing oxygen serving as a gasification agent and hydrogen for the synthesis process, and of a combustion apparatus, which is connected to the output of the gasification apparatus for carbon-containing gasification residues and to the oxygen outlet of the device for effecting the electrolysis of water. According to the invention, at least a portion of the waste steam from the drying device and at least a portion of the residual gas arising during synthesis are fed to the gasification process in the gasification apparatus. In addition, the carbon-containing residuals from the gasification apparatus and a portion of the oxygen produced in the device for effecting the electrolysis of water can be fed to a combustion apparatus, and the carbon dioxide-containing and oxygen-containing waste gas from the combustion apparatus can be fed to the combustion apparatus in the form of a gasification agent.
