Abstract: A friction modifier for combustible fuels is provided that is prepared by combining a saturated carboxylic acid and an alkoxylated amine or etheramine. Furthermore, there also is an additive concentrate for use in fuels, especially in gasoline for internal combustion engines, comprising (a) a friction modifier comprising of a branched saturated carboxylic acid salt of an alkoxylated amine, such as isohexyloxypropylamine isostearate; (b) a detergent package, as well as the combustible fuels containing this additive concentrate. The particular selection of friction modifier (a) enables a stable additive concentrate to be formulated providing a significant benefit in friction loss when incorporated in gasoline used to fuel an internal combustion engine, and hence an improvement in fuel economy.

Abstract: An artificial firelog and firestarter chip producing apparatus comprising a cutting assembly, a compression conveyor auger assembly and a die. The apparatus converts standard waxed corrugated cardboard boxes into artificial firelogs by first slicing cardboard sheets into cardboard strips, then chopping the cardboard strips into cardboard segments in the cutting assembly. The cardboard segments are compressed and in the compression conveyor auger assembly and extruded in the die to form generally circular, longitudinally-shaped sections of a firelog. Firestarter chips are fabricated by the cutting assembly, which slices cardboard sheets in conjunction with paper sheets into cardboard and paper strips, then chopping the cardboard strips into cardboard segments and the paper strips into paper mix.

Abstract: A free-flowing, hydrophobic starch composition has a near-neutral dry product pH. Methods for making the hydrophobic starch composition by preparing an aqueous mixture comprising a starch, a siliconate, and an acid, where the aqueous mixture has a near-neutral pH, and drying the starch solids to obtain a hydrophobic starch. Novel fuel compositions comprise hydrophobic starch which can be used in internal combustion engines, such as diesel engines. Hydrophobic starch compositions may be used as fuels or fuel components. Novel methods of fueling and operating internal combustion engines use hydrophobic starch as fuel or fuel components.
Abstract: A process of treating high sulfur coal to reduce sulfur dioxide emission when the high sulfur coal is burned comprising placing coal in pressure tank (16) of reduced pressure sufficient to fracture a portion of the coal by withdrawing ambient fluids trapped within the coal. The fractured coal is contacted with an aqueous silica colloid composition supersaturated with calcium carbonate via conduit (21), and the majority of the aqueous composition is then removed from contact with the coal. The aqueous composition-treated coal is pressurized in pressure tank (16) under a carbon dioxide atmosphere for a period of time sufficient for the calcium carbonate to enter fractures in the coal produced in the first step.

Abstract: Embodiments of the present invention are directed toward systems and methods of providing a low-emissions diesel fuel for use in cold climates. Such fuels may be prepared by a Fischer-Tropsch process and include a pour point depressant. Furthermore, the fuel is used in conjunction with a heated fuel delivery system so that low cloud points are not necessary. Fuels prepared according to embodiments of the present invention may be produced in higher yields than otherwise possible because a higher paraffin wax content can be tolerated, thus obviating the need to remove or exclude the wax. These fuels are characterized by a sulfur content less than 1 ppm, a cetane number greater than 60, an aromatics content less than 1 wt %, and a difference between the cloud and pour points that is greater than about 5° C. The present fuel may be prepared by a Fischer-Tropsch synthesis from any number of carbon-containing sources such natural gas, coal, petroleum products, and combinations thereof.
Abstract: The invention relates to low-temperature-stabilized additives for fuel oils having a sulfur content of up 0.05% by weight, comprising fatty acid mixtures of A1) from 1 to 99% by weight of at least one saturated mono- or dicarboxylic acid having from 6 to 50 carbon atoms, A2) from 1 to 99% by weight of at least one unsaturated mono- or dicarboxylic acid having from 6 to 50 carbon atoms, and B) at least one polar nitrogen-containing compound which is effective as paraffin dispersant in middle distillates, in an amount of from 0.01 to 90% by weight, based on the total weight of A1), A2) and B); and to the use of said mixtures for improving the lubrication properties of low-sulfur middle distillates.
