RU-2861450-C1 - FUEL ADDITIVE

Abstract

FIELD: oil refining. SUBSTANCE: invention relates to petrochemistry and the automotive industry. The invention relates to a fuel additive which includes a polyetheramine-based detergent, a synthetic-based carrier fluid, an organic peroxide, as well as a solvent and a co-solvent. The solvent is a hydrocarbon aromatic solvent. Di-tert-butyl peroxide is used as the organic peroxide, and the co-solvent has an alcohol base. The synthetic-based carrier fluid used is isoparaffinic oils of Group III base oils, or polyalphaolefins of Group IV, or dicarboxylic acid esters of Group V. The components in the additive are used in the following ratio, mas.%: polyetheramine-based detergent 5-10, synthetic-based carrier fluid 18-22, di-tert-butyl peroxide 3-5, hydrocarbon aromatic solvent 30-35, alcohol-based co-solvent the rest up to 100. EFFECT: creation of a fuel additive that helps to wash away old deposits and prevent the formation of new ones, increase the fuel combustion temperature, create conditions for the afterburning of accumulated soot and other deposits on the working surfaces of the catalyst and oxygen sensors. 1 cl, 4 ex

Description

AREA OF TECHNOLOGY The invention relates to oil refining, petrochemicals, and the automotive industry, specifically to fuel additives for automotive fuel. It allows for cleaning and normalizing the operation of an automotive catalytic converter without removing it. LEVEL OF TECHNOLOGY The prior art includes patent RU 2609767 IPC C10L 1/18, C10L 1/28, C10L 1/12, C10L 10/00, published on 02.02.2017. The invention relates to the field of petrochemistry and oil refining, in particular to the production of environmentally friendly fuels with a reduced content of harmful substances in fuel combustion products. The beneficial effect of the present invention is a reduction in the content of harmful substances in exhaust gases, an increase in the completeness of fuel combustion and a reduction in specific fuel consumption, a reduction in deposits on intake and exhaust valves, a reduction in carbon deposits in the combustion chamber, a reduction in wear of the cylinder-piston group of engines, a reduction in the temperature of exhaust gases in order to reduce the formation of thermal nitrogen oxides, and stabilization of the operating parameters of the additive. The prior art includes patent RU 2616624 IPC C10L 10/00, C10L 1/22, C10L 1/18, C10L 1/28, published on 18.04.2017. The invention relates to oil refining, petrochemistry and the automotive industry, in particular to additives for motor gasolines for the purpose of imparting detergent, anti-corrosion, antioxidant, demulsifying and antistatic properties to them, as well as for improving environmental performance. The beneficial effect of the present invention is the reduction of carbon deposits in the combustion chamber and deposits on engine valves, and the reduction of the content of harmful substances in exhaust gases. The prior art includes patent RU 2361903 IPC C10L 1/00, C10L 1/10, C10L 1/12, published on July 20, 2009. The present invention concerns new types of fuel additive compositions, each of which may include an alloy of two or more different metals. The advantageous effect of the present invention is the creation of an additive that solves the problems of: reduced planned efficiency, increased emissions of environmental pollutants, reduced process time due to deposits in the combustion system, and corrosion of system equipment due to the presence of unwanted fuel-generated corrosion precursors that turn into corrosive substances under certain combustion conditions. The disadvantages of the above analogs are that the compounds do not clean oxygen sensors and do not normalize the operation of the catalytic converter, since they do not contribute to the creation of conditions for the afterburning of accumulated soot and other deposits on the working surfaces. Patent RU 2609767 IPC C10L 1/18, C10L 1/28, C10L 1/12, C10L 10/00, published 02.02.2017, is taken as the closest analogue, the disadvantages of which are eliminated by the claimed technical solution. DISCLOSURE OF THE ESSENCE OF THE INVENTION The technical challenge is to develop a fuel additive that can clean and normalize the operation of automotive catalytic converters and oxygen sensors. The technical result of the proposed invention consists in the creation of a fuel additive that facilitates the washing away of old deposits and the prevention of the formation of new ones, an increase in the combustion temperature of the fuel, and the creation of conditions for the afterburning of accumulated soot and other deposits on the working surfaces of the catalyst and oxygen sensors. The technical result can be achieved by a fuel additive comprising a detergent based on polyetheramine, a carrier liquid on a synthetic base, an organic peroxide, as well as a solvent and a co-solvent, wherein the solvent is a hydrocarbon aromatic solvent, di-tert-butyl peroxide is taken as the organic peroxide, and the co-solvent has an alcohol base, characterized in that isoparaffin oils of group III of base oils, or polyalphaolefins of groups IV, or esters of dicarboxylic acids of group V are used as the carrier liquid on a synthetic base, with the following ratio of components, wt. %: polyetheramine-based detergent5-10synthetic carrier fluid18-22di-tert-butyl peroxide3-5hydrocarbon aromatic solvent30-35alcohol co-solventthe rest up to 100 IMPLEMENTATION OF THE INVENTION All modern cars are equipped with catalytic converters. This component was designed primarily to reduce the amount of harmful substances in exhaust gases. The main problem with catalysts is the formation of contamination from oil residues, as well as carbon deposits resulting from incomplete combustion of fuel, which leads to a decrease in the efficiency of the catalyst. The stated composition allows to solve the above mentioned problems: - a detergent based on polyetheramine, for example the product known under the trade name DE 94, produced by Total Additifs ET Carburants Speciaux (France), gives the additive cleaning properties throughout the entir
