Benefits of technology

[0016]Another aspect of the invention as described herein is the use of additives such as (a) thermal stabilizers, (b) corrosion inhibitors, (c) cetane improvers, (d) detergents, (e) lubricity improvers, (f) dyes and markers, (g) anti-icing additives, (h) demulsifiers / anti-haze additives, (i) antioxidants, (j) metal deactivators, (k) biocides, (l) static dissipater additives, (m) low temperature operability / cold flow additives, and (n) antifoams; in combination with the disclosed novel additive composition; in combination with the renewable fuel and novel additive composition; or in combination with the renewable fuel, petroleum fuel blend and the novel additive composition, to not only directly enhance fuel particulate inhibition, but also other fuel properties.

Problems solved by technology

The environmental impact of burning fossil fuels is a widely recognized global issue.
Although these renewable fuels have many positive political and environmental attributes, they also have certain negative characteristics which must be taken into consideration when utilizing the material as an alternative fuel or as a blend stock for petroleum diesel.

examples

[0240]Certain substances that are soluble or appear to be soluble in renewable fuel or in renewable fuel petroleum blends at ambient temperatures can upon cooling or standing for extended periods, come out of solution and possibly block fuel delivery systems.

[0241]Two testing methods were used to assess the propensity of a fuel to form in-soluble substances during extended storage.

[0242]Particulate Inhibition testing method—Filtration Test (ASTM):

[0243]This test method covers the determination by filtration time after cold soak the suitability of a Biodiesel (B100) for blending with light-middle and middle distillates to provide adequate low temperature operability performance to at least the cloud point of the finished blend. The test method can be used as a means of evaluating the propensity of a biodiesel and biodiesel blends to cause fuel filter plugging. Fuels that give short filtration times are expected to give satisfactory operation down to the cloud point of biodiesel blend...

Abstract

Disclosed herein is a fuel oil composition comprising a renewable fuel or a blend of petroleum based fuels with renewable fuels, also containing an additives composition to enhance the base and combined fuel's resistance to forming insoluble particulates upon storage at diminished operating temperatures. Further described is the additive package used to inhibit particulate formation.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to fuel oil compositions. The invention more specifically relates to renewable fuels, and blends of petroleum fuels with renewable fuels, in combination with a novel additive composition designed to diminish particulate formation upon storage of the renewable fuel and renewable fuel petroleum fuel blends.BACKGROUND OF THE INVENTION[0002]The environmental impact of burning fossil fuels is a widely recognized global issue. There are governmental and civil initiatives to diminishing this detrimental effect. Two of the major initiatives which are affecting the liquid fuel industry are the EPA regulation to limit S content of on-road fuels, and the ever increasing awareness for the need to use renewable fuels.[0003]In order to meet emissions and fuel efficiency goals, automotive Original Equipment Manufacturers (OEM's) are investigating the use of NOx traps, particulate traps and direct injection technologies. Such traps and ca...
