Diesel substitutes There are several diesel substitutes available: Liquid bio-fuels: - Alcohols (ethanol), e.g. produced from sugar beet or potatoes, maize, wheat
- Natural oils, e.g. produced from rape seed or soy beans
- Oil esters (biodiesel), e.g. produced from rape seed or soy bean oil, recovered vegetable and animal fats
"Synthetic" fuels (not treated here): - Synthetic middle distillates (SMD) and Dimethyl Ether (DME): to be produced from various carbonaceous feedstocks, including natural gas, residual fuel oil, heavy crude oils and coal via the production of synthesis gas
Natural gas: - LNG (liquefied natural gas) / CNG (compressed natural gas)
Rape oil methyl-ester (RME) The following evaluation refers to biofuels, particularly to rape oil methyl-ester (RME). RME is esterified rape-oil. The esterification process uses the catalytic impact of methanol and heat for producing RME. Fields of application: All fields of application of diesel fuel. Manufacturer: There are numerous RME suppliers including - Oelmühle Hamburg Aktiengesellschaft (Germany)
- Rheinische Bioester GmbH (Germany)
- Diester Industrie (France)
- Novaol (Italy)
