Abstract
Official abstract text for this publication.
Embodiments of the invention provide a method of inhibiting precipitation of biodiesel fuel components. The method includes providing a biodiesel fuel composition; providing a copolymer comprising at least first and second polymer units, said first polymer units derived from a carboxylic acid anhydride and said second polymer units derived from an olefin; and blending said copolymer with the biodiesel fuel to form a treated fuel composition. Alternatively, instead of the copolymer, a dialkylene glycol additive can be provided. Embodiments of the invention provide a method of reducing the cold soak filter blocking tendency of a biodiesel fuel composition.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of reducing the cold soak filter blocking tendency of a biodiesel fuel composition, comprising: providing a biodiesel fuel comprising a biocomponent portion, optionally a non-biocomponent portion, and one or more sterol glucosides and/or one or more monoglycerides, which biodiesel fuel has a CSFBT of at least about 1.4; providing a dialkylene glycol additive composition that comprises or is diethylene glycol and/or dipropylene glycol in an amount, relative to an amount of the biocomponent portion, of at least 0.7% and at most 20.0% volume/volume; and blending the additive with the biodiesel fuel to form a treated fuel composition, which has a CSFBT from about 1.0 to about 1.3. 2. The method of claim 1 , wherein one or more of the following are satisfied: the dialkylene glycol additive is present in an amount, relative to an amount of the biocomponent portion, of at least 1.0% v/v; the one or more sterol glucosides are present in a non-zero amount up to 200 mg/kg; and the one or more monoglycerides are present in a non-zero amount up to 20000 mg/kg.
