Standardanforderungen an Rapsoelmethylester als Motorenkraftstoff

The author presents the findings of a bibliographic search on the production and appications of rapeseed methyl esters as engine fuels and their environmental compatibility. The quality characteristics of vegetable oil methyl esters and their effects on fuel quality are gone into, and test procedures are described. The second and third parts of the publication contain the results of a questionnaire and a workshop on this subject.

Kraftstoff aus Raps. Bereich 3: Chemische Umwandlung. Vergleich der Verfahren zur Umesterung von Triglyzeriden zu Methylester und zur Aufreinigung des Hauptproduktes Abschlussbericht

By transesterification of the rape oil triglycerides with methanol to rape oil methyl ester a synthetic fuel (biodiesel) is obtained with properties very similar to diesel fuel, and which can be directly used in existing diesel motors. Technical processes for the production of rape oil methyl ester are described and analyzed taking into account process chemistry, chemical engineering, process engineering and economical aspects. Four different project types are defined and subjected to a detailed economical analysis: small plants (< 2.000 t/a; rural recycling plants), agro-refineries (< 15.000 t/a; regionary plants), annex plants (> 30.000 t/a; annex to oil mills) and high-capacity plants (> 100.000 t/a).
