Dimethyl ether from waste gas

Résumé ou Introduction

Zero emission is the realization of carbon dioxide sinks, by converting carbon dioxide (CO2) to another component. We do not understand under zero emission storing carbon dioxide in wholes, the ocean, or in tanks. If we compare with a biological plant, we have to learn that the biological plant is converting carbon dioxide (CO2) and water (H2O) to biomass and oxygen based on solar energy.

The process is divided into two parts, the light cycle and the dark cycle, optimized to the day and night cycle on earth (or in mechanistic interpretation: on the rotation of the earth around the axis). The aim of this photosynthesis process is to produce biomass during the growth process, oxygen is a waste product. Transferring the conversion of water and carbon dioxide to energy, we need hydrogen and as a waste product oxygen.

If we now turn over to technical processes which include up scaling we need a fuel which can be produced from biogenic mass and gases and additional from water and carbon dioxide. In this article we focus on dimethyl ether (DME). To enable this process we need at least electric energy provided by the volatile wind and solar energy and by nuclear power.
