Method for preparing and using an alcohol and use of the alcohol to improve the efficiency and performance of a combustion engine

摘要

Providing and using storable and transportable alcohol containing cooling liquid (108), comprises: providing carbon dioxide and hydrogen gas; providing a gaseous starting material comprising the carbon dioxide gas and the hydrogen gas; introducing the starting material into a reactor; passing the starting material through a reaction section of the reactor for synthesizing the cooling liquid; providing the cooling liquid at an outlet end of the reactor; and using the cooling liquid before or in the internal combustion for cooling intake air, compressor air, charge air and/or a fuel-air mixture. Providing and using storable and transportable alcohol containing cooling liquid (108), comprises: providing carbon dioxide gas as carbon source; providing hydrogen gas; providing a gaseous starting material comprising the carbon dioxide gas and the hydrogen gas; introducing the starting material into a reactor; passing the starting material through a reaction section of the reactor, which is at least partially provided with a catalyst for synthesizing the cooling liquid on the catalyst; providing the cooling liquid comprising a mixture of alcohol and water, at an outlet end of the reactor; and using the cooling liquid before or in the internal combustion engine that is supplied with a fuel, for cooling intake air, compressor air, charge air and/or a fuel-air mixture, which is supplied to the internal combustion engine, by evaporating the cooling liquid.
