Abstract

Die vorliegende Arbeit behandelt grundlegende Fragestellungen wie die Synthese und Stoffeigenschaften bis hin zur Prozessentwicklung bzw. -optimierung von Oxymethylenethern (OME). Dieser innovative Dieselkraftstoff kann aus nachwachsenden Rohstoffen gewonnen werden. OME tragen nachweislich zur Senkung von Stickoxid- und Partikelemissionen, im Vergleich zu konventionellem Diesel, bei.

Abstract

Oligomeric oxymethylene ethers (OMEs) are promising fuels for internal combustion engines with self-ignition. A tremendous reduction of soot, nitrogen oxide and hydrocarbon emissions can be realized by employing OMEs. This work describes the synthesis of OMEs from dimethyl ether (DME) and trioxane. Zeolite H-BEA 25 was found to be a suitable catalyst for this reaction and a study on reaction parameters (e.g. temperature, reactant feed ratio and reaction time) has been carried out. A maximum DME conversion of 13.9 wt% could be obtained and the maximum reactant-related product yield for OME 3–5 was 8.2 wt%. An OME formation mechanism is proposed which explains the observed product spectrum. [ABSTRACT FROM AUTHOR]
