  • Patent number: 8147568
    Abstract: A diesel fuel composition containing metallic additives that are stabilized against phase separation. The diesel fuel contains a colloidally dispersed or solubilized metal catalyst compound, which can be used for diesel particulate trap regeneration and, as a stabilizer, 5-1,000 ppm (weight) of an oil-soluble or oil-dispersible organic compound having a lipophilic hydrocarbyl chain having attached directly thereto at least two contiguous polar head functional groups, i.e., the functional groups are separated by no more than three carbon atoms. The diesel fuel composition is particularly suitable for use with diesel engines fitted with a particulate trap for emissions control.

  • Publication number: 20120077234
    Abstract: A method and system are provided for producing biofuel from cellulosic feedstock. In the method, the cellulosic feedstock is pretreated to separate cellulose, hemicellulose, and lignin. Thereafter, the cellulose and hemicellulose are converted into sugars through enzymatic hydrolysis. Then, the sugars are converted into lipids, e.g. triglycerides, through a microbial process. Specifically, heterotrophic microalgae is grown on the triglycerides and forms triglycerides. While triglycerides are formed from the cellulose and hemicellulose, the lignin is converted into ringed hydrocarbons, such as aromatic hydrocarbons and cycloalkanes, e.g., cycloparaffins. To form the biofuel, the triglycerides and ringed hydrocarbons are processed together. During this step, the triglycerides are converted into straight chain paraffins and esters. Preferably, the biofuel is a surrogate for jet quality JP-8 fuel.

  • Patent number: 8142524
    Abstract: The present invention is generally directed to novel fuel compositions and to methods (i.e., processes) for enhancing the combustion efficiency and/or other properties of diesel fuels, particularly wherein such diesel fuels are, or comprise, biodiesel, such biodiesel typically having poorer low-temperature properties than traditional (petroleum) diesel. Generally, such fuel compositions are provided by the creation and inclusion of a quantity of one or more epoxy-ester species, such species serving as combustion improvers for the fuel composition of which they are part.

  • Publication number: 20110232170
    Abstract: The invention describes citric acid esters as heating materials and fuels in stationary and mobile internal combustion engines and also in heating installations. Such propellants and fuels are characterized in particular by the fact that they burn completely without soot or with very little soot, therefore cause distinctly lower emissions of soot or fine dust than known fossil and regenerative fuels such as gasoline, diesel, kerosene, vegetable oils and biodiesel. Citric acid esters can be obtained completely from regenerative vegetable sources and are therefore CO2 neutral.
