A biofuel product having constituents selected from the group including fat, oil and/or grease components. A container is formed of a biodegradable material having a multiplicity of openings of a size and shape adapted for allowing the fat, oil and/or grease components to pass through the openings to an interior area of the container. An absorbent capture material is positioned in the container and holds a quantity of the fat, oil and/or grease. The container, capture material and fat, oil and/or grease collectively include the biofuel product.

Systems and methods to reduce pour point (PP) temperatures of fat-based compositions for use in transportation fuels. In one or more embodiments, methods and systems reduce the pour point of rendered fats using biologically-derived plant oils for effectively transporting the blended fat based compositions over long distances, thereby advantageously decreasing the heating and mixing requirements needed to maintain the compositional temperature above the pour point. In certain embodiments, the fat based composition comprises rendered animal fats, such as tallow in combination with distilled corn oil (DCO).

Method to improve or maintain stability and/or compatibility of a residual hydrocarbon fuel comprising: (a) blending at least 5-95% m/m of a residual hydrocarbon component with at least 5-80% m/m of a fatty acids alkyl esters component or (b) blending at least 5-80% m/m of a fatty acids alkyl esters component with a stable residual fuel composition comprising (i) at least 5-95% m/m of a residual hydrocarbon component and (ii) up to 90% m/m of a non-hydroprocessed hydrocarbon, a hydroprocessed hydrocarbon or any combination thereof; wherein the fatty acids alkyl esters component is blended with the stable residual fuel composition before at least one other fuel composition that decreases the asphaltenes solvency power of the residual fuel composition is added thereto.

The present invention relates to middle distillate fuel blends, in particular renewable diesel fuel blends comprising a mixture of aryl ethers.

A method for applying a chemical treatment to a process stream in an ethanol production/corn oil extraction system. The method includes applying the chemical treatment to the process stream before or during fermentation of an emulsified oil precursor product in the process stream to demulsify the emulsified oil precursor product, and extracting the demulsified oil from the emulsified oil precursor product.
