Definitions

• the invention relates to an engine fuel and a method for its production, which consists of a base fuel consisting of hydrocarbons or predominantly hydrocarbons and additions of alcohols and / or ethers and / or ketones and additives and optionally water and aromatics.
• Bioethanol can be obtained in burners with relatively little expenditure on equipment and energy. Since this bioalcohol also contains organic impurities, e.g. Aldehydes, ketones, acetic acid and esters have so far not considered the use of this bioethanol in motor vehicles as an additive to conventional petrol fuels feasible, and in addition the problem of complete miscibility at particularly low outside temperatures due to the high water content of the bioalcohol was not considered economically solvable has been.
• organic impurities e.g. Aldehydes, ketones, acetic acid and esters
• a typical bioethanol has e.g. B. the following data:
• the object of the present invention was therefore to provide a fuel which avoids the specified technical problems, meets all the requirements of the fuel standards, takes into account the availability of the additional components and can be offered to the motorist in the existing gas station distribution network without any problems.
• the object was achieved according to the invention by a new motor fuel consisting of base fuel, hydrocarbons or predominantly hydrocarbons and consisting of additions of alcohols and / or ethers and / or ketones and optionally aromatics, additional water and additives and compounds of the lead, characterized thereby that it contains> 0 to 10 vol.% ethanol with more than the ethanol / water azeotrope (at normal pressure) corresponding water content,> 0 to 10 vol.% butanol (s) and;> 0 to 5 vol.% methanol and / or> 0 - 15 vol.% methyl tert-butyl ether and / or> 0 - 15 vol.% acetone.
• the fuel according to the invention is excellently suited for the usual motor vehicle engines, can be mixed as desired with fuels already on the market, conversions to the carburettors and engines and other parts that use the fuel come into contact, are not required, all requirements of the DIN standard be fulfilled and the fuel can be made available to the driver at the existing filling stations.
• the fuel according to the invention contains from> 0 to 10% by volume of ethanol with a higher water content than the ethanol / water azeotrope, but can also contain proportions of pure ethanol and / or ethanol / water azeotrope and / or ethanol or technical grade ethanol contain with less water, preferably> 0 - 5 vol.% bioethanol is used, furthermore> 0 to 5 vol.% methanol can be contained, which can be technical, undistilled methanol, or topped technical, undistilled methanol. In the latter part of the impurities contained in technical methanol is driven off overhead.
• butanol s
• tert-butanol tert-butanol
• butanol mixtures can also be used, methyl tert-butyl ether and acetone.
• Other ethers such as e.g. Dimethyl, diethyl, methyl tert-amyl ether and components such as e.g. Aromatics. Water can also be added.
• Acetone can be added as pure or technical or bioacetone.
• the basic hydrocarbons used are preferably super gasoline or normal gasoline or mixtures thereof which comply with the fuel standards.
• the basic hydrocarbons can already contain additives or even methanol additions of> 0 to 5 vol.% And / or butanols of> 0 - 10 vol.% Butanol (s), these having to be taken into account accordingly when adding bioethanol according to the invention.
• Keropur As an additive, numerous additives that are available on the market, such as Keropur from BASF, can be used. Lead can also be added in the form of its compounds commonly used in fuels.
• the components can be mixed together by mixing a high octane hydrocarbon-based super fuel component and / or a lower octane hydrocarbon-based normal fuel component with bioethanol, methanol, butanol (s), methyl tert-butyl ether, acetone and the additives, has proven to be a preferred embodiment of mixing super fuel and / or normal fuel, which may already contain> 0-5 vol.% methanol and> 0-10 vol.% butanol (s), with a premixed component containing bioethanol, butanol ( e) and / or methanol and / or methyl tert-butyl ether and / or acetone and optionally additives and lead compounds.
• a typical mixture according to the invention has, for example, the following composition:
• This mixture was added to a super fuel containing no methanol / butanol additives, so that a mixture of 7 vol% and 93 vol% super fuel was obtained.
• This mixture was added to a mixture of 80% by volume of super fuel and 10% by volume of normal fuel, so that a mixture of 90% by volume of super / normal fuel and 10% by volume of mixture of the oxygen-containing compounds was obtained.
• This mixture was added to super fuel so that a mixture of 90% by volume of super fuel and 10% by volume of the oxygen-containing compounds was obtained.
• the present invention is of great importance with regard to reducing the dependency on imported mineral oil, since it makes it possible for the first time to use fuel alcohol (bioalcohol) which can be obtained in fuels even with relatively little energy expenditure. Contrary to the prejudice of experts, the extensive investigations by the applicant have shown that the contaminants contained in this alcohol cause neither damage to motor vehicle parts nor increased environmental pollution.
