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:
Unleaded aviation gasolines having heats of combustion and octane qualities deemed necessary for use under actual service conditions are formed from blends of specified proportions of aviation alkylate, ether blending agent, a cyclopentadienyl manganese tricarbonyl and optionally other appropriate hydrocarbons falling in the gasoline boiling range.
Abstract:
Dihydrocarbyl diazene dicarboxamides (DHCDD) have been found to effectively reduce the ignition delay and/or as effective cetane number improvers in diesel fuels and is suitable for use in modern engines. The cetane number of a fuel composition is a measure of its ease of ignition and combustion. With a lower cetane number fuel a compression ignition (diesel) engine tends to be more difficult to start and may run more noisily when cold; conversely a fuel of higher cetane number tends to impart easier cold starting, to lower engine noise, to alleviate white smoke ("cold smoke") caused by incomplete combustion.
Abstract:
A diesel fuel composition comprising, as an additive, the product of a Mannich reaction between: (a) an aldehyde; (b) an amine; and (c) a substituted phenol; wherein the phenol is substituted with at least one branched hydrocarbyl group having a molecular weight of between 200 and 3000; and wherein in the Mannich reaction used to form the additive the molar ratio of component (a) to component (b) is 2.2-1.01:1; the molar ratio of component (a) to component (c) is 1.99-1.01:1 and the molar ratio of component (b) to component (c) is 1:1.01-1.99.
Abstract:
The present invention relates to using a marker in a functional fluid, which survives the use of the functional fluid in an application, with a reagent solution to identify the functional fluid rapidly either before, during or after the functional fluid's use and which is a suitable method for identifying a functional fluid in the field, and which may employ the use of test wipe, or medium, that contains the reagent solution.
Abstract:
Provided are additives of formula I for use in hydrocarbonaceous compositions, such as petroleum or liquid fuels: (I) wherein R1, R2, R3, R4, and R5 are as defined herein. The additives improve the corrosion resistance of the compositions and, when the composition is biodiesel, also improve microbial resistance. The additives further enhance the antimicrobial efficacy of any added biocides contained in such compositions.
Abstract:
The invention discloses a watered compounded emulsifier formulation for gasoline, its preparation, and a method of making watered emulsified gasoline with the formulation and its product. The said formulation consists of sorbitan monomyristate 60-75%, Peregal O 7-10%, dispersing agent IW 5-8%, 12-hydroxyl lithium stearate 2-4%, wool fat 4-8%, azimino-benzene 4-7% and isopentanol 1-4% by weight. The emulsified gasoline made with the present watered compounded emulsifier has higher combustion efficiency, saving oil and reduced environmental pollution.
