Continuously operated test stand
- Two solid catalyst systems can be tested in a continuous flow fixed bed reactor successively.
Use of molecular gaseous formaldehyde and water sensitive catalysts
Molecular formaldehyde tends to polymerize in the presence of water and cannot be bought in gas bottles. Because of this, the gaseous formaldehyde is
synthesized in situ by the decomposition of 1,3,5-trioxane and used instantaneously.
The catalyst can be filled into the reactors in the absence of air. Therefore, oxygen and water sensitive catalyst can be used.
Continuous syntheses of Oxymethylene Ether
Oxymethylene ether (OMEn) with the general formula
CH3(-OCH2-)nO-CH3 (n = 3-5) are investigated as sustainable synthetic fuels for the use in diesel-vehicles. Because of the lack of
C-C-bonds, OMEs burn without soot formation and can thereby reduce the formation of nitrogen oxides significantly.
The continuous synthesis is based on the reaction of molecular formaldehyde with Dimethoxymethane (OME1) or Dimethylether (DME).
All gaseous starting materials and products are analyzed by online gas chromatography using an AGILENT 8890 gas chromatography system.
