TECHNOLOGY FOCUS - INDUSTRIAL STANDARDS - Preferred Components: The fuel composition or liquid hydrocarbon fuel is a biodiesel of type B100 having a value of induction time of greater than or equal to 8 hours obtained by Rancimat test according to standard DIN EN 15751 and a gain value of induction time of greater than or equal to 2 obtained by the Rancimat test according to DIN EN 15751.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The fuel composition or the liquid hydrocarbon fuel is stored at a temperature of below 0 degrees C, preferably less than or equal to -10 degrees C. The fuel composition or liquid hydrocarbon fuel: is obtained from middle distillates with a boiling point of 100-500 degrees C, preferably 140-400 degrees C; and is derived from vegetables oil, animal oil and/or their esters of oils, and biodiesel of animal and/or vegetable origin. Preferred Components: The esters are fatty acid methyl esters or fatty acid ethyl esters, preferably vegetable oil methyl esters or vegetable oil ethyl esters.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The modified alkylphenol-aldehyde resin is diluted in a solvent, preferably aromatic solvent. The aldehyde resin reduces the amount of deposits formed during the storage of the fuel composition or liquid hydrocarbon fuel. The alkylphenol-aldehyde resin used in the fuel composition or liquid hydrocarbon fuel is in combination with one or more other additives. The other additives are dispersants/detergents, carrier oils, anti-clouding agents, metal deactivators, metal passivators, antioxidants, dyes, antistatic additives, corrosion inhibitors, biocides, markers, thermal stabilizers, emulsifiers, friction reducer agents, surfactants, cetane improvers, anti-disturbance agents, conductivity improver additives, reodorants, and/or lubricity additives. The modified alkylphenol-aldehyde resin is present in an amount of 5-5000 ppm by mass, preferably 50-600 ppm. The aldehyde resin is obtained: from at least one alkylphenol substituted in para position, preferably from p-nonylphenol; from at least one aldehyde and/or a ketone including formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, 2-ethyl hexanal, benzaldehyde, or acetone; from at least one alkylamine having at least one primary amine group; and from at least one fatty chain alkylamine or alkylamine mixture with a fatty chain, where the alkylamine(s) have 12-24C, preferably 12-22C.
