Abstract
Abstract A stabilizing agent which produces stable fuel oil-water mixtures for use as fuels with consequent fuel savings comprises: -a combustible emulsifier 6 to 11.5 parts by weight -ferrocene 4 to 9 parts by weight -magnesium (as an oil-soluble magnesium -salt) 4.5 to 9.2 parts by weight -anionic surfactant 1.4 to 3 parts by weight -benzoic acid 0 to 12 parts by weight -in an oil-based liquid medium. -

______________________________________
Claim 12
Dependent Claim
58 words
A method of forming a stabilising agent according to claim 1, preparing: (1) a solution of the magnesium salt and the anionic surfactant in a paraffin solvent (2) a solution of ferrocene in oil (3) a solution of the emulsifier and the benzoic acid in an organic solvent system; and combining the three solutions (1), (2) and (3).
Claim 13
Dependent Claim
14 words
A method according to claim 11, in which the oil is a fuel oil.
Claim 14
Dependent Claim
31 words

Claim 15
Dependent Claim
26 words
A method of forming a stabilised oil-water mixture, comprising simultaneously adding water and the stabilising agent set forth in claim 1 to oil with vigorous mixing.
Claim 16
Dependent Claim
25 words
A method according to claim 14, in which the stabilising agent is first added to the water and the combined mixture added to the oil.
Claim 17
Dependent Claim
36 words
