Title (EN) LOW-SULPHUR DIESEL FUEL AND USE OF FATTY ACID MONOALKYL ESTERS AS LUBRICANT IMPROVERS FOR LOW-SULPHUR DIESEL FUELS
(FR) CARBURANT DIESEL A FAIBLE TENEUR EN SOUFRE ET UTILISATION D'ESTERS MONOALKYLIQUES D'ACIDES GRAS COMME AGENTS AMELIORANT LE POUVOIR LUBRIFIANT POUR DES CARBURANTS DIESEL A FAIBLE TENEUR EN SOUFRE
(DE) SCHWEFELARMER DIESELTREIBSTOFF SOWIE VERWENDUNG VON FETTSÄUREMONOALKYLESTERN ALS SCHMIERFÄHIGKEITSVERBESSERER FÜR SCHWEFELARME DIESELTREIBSTOFFE
Abstract:
(EN) The invention relates to a low-sulphur diesel fuel containing a maximum of 0.2 wt. % sulphur and fatty acid monoalkyl esters in an amount between 10 and 50,000 ppm as lubricant improver, whereby the fatty acid ester of the fatty acid monoalkyl ester is derived from at least 50 %, in particular at least 70 % of saturated fatty acids. It has been shown that said fatty acid esters exhibit a markedly better lubricant improvement in low-sulphur fuels than biodiesel derived from rapeseed oil or soya oil.
(FR) L'invention concerne un carburant diesel à faible teneur en soufre, qui contient au maximum 0,2 % en poids de soufre et des esters monoalkyliques d'acides gras, dans une quantité comprise entre 10 et 50.000 ppm, comme agents améliorant le pouvoir lubrifiant. Le carburant diesel selon l'invention est caractérisé en ce que les restes acides gras des esters monoalkyliques d'acides gras proviennent à au moins 50 %, notamment à au moins 70 %, d'acides gras saturés. Il a été démontré que ces esters d'acides gras entraînent une amélioration du pouvoir lubrifiant dans le carburant diesel à faible teneur en soufre significativement meilleure que des biodiesels à base d'huile de colza ou d'huile de soja.
(DE) Die Erfindung betrifft einen schwefelarmen Dieseltreibstoff enthaltend max. 0,2 Gew.-% Schwefel und Fettsäuremonoalkylester in einer Menge zwischen 10 und 50.000 ppm. als Schmierfähigkeitsverbesserer, wobei die Fettsäurerester der Fettsäuremonoalkylester zu mindestens 50%, insbesondere mindestens 70% von gesättigten Fettsäuren stammen. Es hat sich gezeigt, dass diese Fettsäureester eine wesentlich bessere Schmierfähigkeitsverbesserung in schwefelarmen Dieseltreibstoff zeigen als Biodiesel aus Rapsöl oder Sojaöl.
