- the usual foam inhibitors include the polysiloxanes mentioned at the outset, alylated polyamines and their mixtures with various N-asylum compounds, such as polyalkenylsuccinic acid amides.
- synergistically effective combination of components A and B in the additive mixture according to the invention leads to a significant improvement in the anti-foam performance of fuels additized with it in comparison with additives of the prior art.
- Blend I Blend I
- Blend II Blend II
- Blend III Blend III
- Lubri ⁇ ity II Tall oil fatty acid mixture obtainable under the trade name Kero ⁇ om LA 99 from BASF AG
- Lubri ⁇ ity III fatty acid ester mixture with glycerin monooleate as the main component.
- a commercially available polysiloxane derivative with the designation anti-foam was used as an anti-foaming agent.
- the additive fuels or blends were added by adding the above.
- Combinations of 5 mg / kg antifoam and 120 mg / kg lubricity improvers Lubricity I to III are obtained.
- the table below shows the values determined for the foam volume and the foam degradation time in dry fuels.
