Abstract:
This invention relates to metal salts of the general formula (I) A M , wherein M represents one or more metal ions, y is the total valence of all M and A represents one or more anion containing groups having a total of about y individual anionic moieties and each anion containing group is a group of formula (II), wherein T is selected from the group consisting of (V) or (VI) wherein each R is independently selected from O and OR wherein R is H or alkyl and each t is independently 0 or 1, wherein each Ar is independently an aromatic group of from 4 to about 30 carbon atoms having from 0 to 3 optional substituents selected from the group consisting of polyalkoxyalkyl, lower alkoxy, nitro, halo or combinations of two or more of said optional substituents, or an analog of such an aromatic group, wherein T is as hereinbefore defined, each R is independently alkyl, alkenyl or aryl having at least 8 carbon atoms, R is H or a hydrocarbyl group, R and R are each independently H or a hydrocarbyl group, each m is independently an integer ranging from 1 to about 10, x ranges from 0 to about 8, and each Z is independently OH, (OR )bOH or O wherein each R is independently a divalent hydrocarbyl group and b is a number ranging from 1 to about 30 and c ranges from 0 to about 3 with the proviso that when t in Formula (II) = 0, or when T is Formula (V), then c is not O provided that the sum of m, c and t does not exceed the unsatisfied valences of the corresponding Ar. Additive concentrates for preparing lubricants and fuels other than two-cycle engine lubricants and fuel compositions as well as lubricating compositions and fuel compositions other than those for two-cycle engines are also disclosed.
Abstract:
An automotive additive composition comprising an automotive additive ingredient and a matrix is described. The automotive additive ingredient may be a fuel additive ingredient such as detergent. The matrix may comprise a gel composition, a solid water removal agents, or a combination comprising one or more of the foregoing matrices. The automotive additive composition may be in the form of a capsule, a gel capsule, or a tablet. Also disclosed is a method of delivering an additive ingredient to a functional fluid of a motor vehicle.
Abstract:
An overbased magnesium composition deposit control additive for residual fuel oils and turbine fuels is an overbased magnesium sulfonate, carboxylate or phanate or mixtures thereof containing at least 14 % and upwards to about 18 % by weight of magnesium and containing a succinic anhydride and lower carboxylic acid co-promoter reaction product. The additive when added to fuel oils, such as residual fuel oils containing high asphaltenes, reduces, if not eliminates, magnesium/asphaltene deposits or sediment and the consequential plugging of filters. The additive also reduces, if not eliminates, vanadium caused corrosion in the turbine. The invention is also the process for preparing the overbased composition or deposit control additive, wherein the overbasing reaction incorporates the combination of a lower carboxylic acid, preferably acetic acid and a succinic anhydride, preferably dodecenyl succinic anhydride (DDSA), as the co-promoter.
Abstract:
Cold high energy fuel compositions for jet, turbine, diesel, fuel oil, and gasoline combustion systems. More particularly, relates to fuels comprised of enhanced combustion structure.
Abstract:
The present invention relates to processes and additive compositions capable of performing at least one of the following: a) stabilizing asphaltenes flocculated and/or precipitated in a petroleum product (as a crude oil, a residue or a fuel oil), rendering thus possible its blending with other petroleum products or its processing or its combustion; b) reducing fouling in petroleum apparatuses; c) achieving yield increase in petroleum refining and/or petrochemical operations; d) reducing particulate and/or SOx and/or NOx emissions during combustion of fuels; e) reducing fouling and/or coke formation in catalysts; f) favouring cleaning and/or decoking of petroleum apparatuses; g) reducing fouling arising from diesel and biodiesel fuels.

Abstract:
The present invention relates to marking a petroleum product with a silent marker, which is an ester derivative of fluorescent material, and to detecting the same. In accordance with the present invention, the silent marker may be detected by measuring the fluorescence generated from the selective hydrolysis of the ester moiety under enzymatic action.
Abstract:
A composition comprising a liquid petroleum product and a colorless marker compound in an amount that is not detectable visually, and a method for marking a liquid petroleum product with a colorless marker compound.
Abstract:
An overbased magnesium composition deposit control additive for residual fuel oils and turbine fuels is an overbased magnesium sulfonate, carboxylate or phenate or mixtures thereof containing at least 14% and upwards to about 18% by weight of magnesium and containing a succinic anhydride and lower carboxylic acid co-promoter reaction product. The additive when added to fuel oils, such as residual fuel oils containing high asphaltenes, reduces, if not eliminates, magnesium/asphaltene deposits or sediment and the consequential plugging of filters.

Abstract:
An additive composition comprising: (a) an ashless dispersant comprising an acylated nitrogen compound; and (b) a carboxylic acid, or an ester of the carboxylic acid and an alcohol wherein the acid has from 2 to 50 carbon atoms and the alcohol has one or more carbon atoms, which provides an improvement in the lubricity of fuel oils and exhibits improved solubility in the fuel oil.
