Patent number: 8663346Abstract: A diesel fuel formulation is provided containing (i) a fatty acid alkyl ester (FAAE), in particular a fatty acid methyl ester (FAME), (ii) diethyl carbonate (DEC) and (iii) an additional diesel fuel component. Also provided is a diesel fuel supplement containing a FAAE and DEC. The inclusion of DEC, in a FAAE or in a diesel fuel formulation containing a FAAE, increase the stability of one or more glycerides present in the FAAE, and/or reduce the concentration of a stability-enhancing additive in the FAAE or fuel formulation, and/or reduce the amount of glyceride precipitates in the FAAE or fuel formulation. The glycerides are in particular saturated monoglycerides.Type: GrantFiled: November 23, 2010Date of Patent: March 4, 2014Assignee: Shell Oil CompanyInventors: Mark Lawrence Brewer, Caroline Nicola Orlebar, Richard John Price, Garo Garbis Vaporciyan
