Dimethyl Ether a rural fuel from water and carbon dioxide (eBook)

Technischer Bericht aus dem Jahr 2018 im Fachbereich Energiewissenschaften, , Veranstaltung: Erneuerbare Treibstoffe, Sprache: Deutsch, Abstract: DME known as dimethyl ether, is a well known chemical substance, the simplest ether, with the chemical structure CH3-O-CH3, consisting of one oxygen atom, two carbon atoms, and six hydrogen atoms. If we us Dimethyl ether as fuel, we recognize, that this fuel brings in one oxygen atom and has six hydrogen atoms. If we compare with methanol (CH3-OH), which has only four hydrogen atoms, dimethyl ether as simplest ether can also be seen as hydrogen carrier. The thermodynamic properties of Dimethyl ether, show that dimethyl ether is liquid at room temperature T=25°C and a pressure of p=6 bar. It is well known that dimethyl ether can be used as an substitute of fossil Diesel fuel, as a synthetic formed Diesel substitute, with highly advanced combustion properties and very low emissions in carbon monoxide(CO), dust and soot and nitrogen oxide(NO2). It easy to handle with the well known LPG (liquid propane gas) technology and can be easily and cheap implemented into heavy Diesel engines. The application of dimethyl ether is wide: transportation, agriculture, civil and rural hotel sector.
