Abstract: A method for producing a renewable base oil from a feedstock of biological origin includes providing a feedstock, the feedstock including: 2-95 wt % of a mixture of free fatty acids; 5-98 wt % fatty acid glycerols selected from mono-glycerides, di-glycerides and tri-glycerides of fatty acids; 0-50 wt % of one or more compounds selected from the list consisting of: fatty acid esters of the non-glycerol type, fatty amides and fatty alcohols; a major part of the feedstock being a mixture of free fatty acids and fatty acid glycerols; subjecting all or part of the feedstock to ketonisation reaction conditions where two free fatty acids react to yield a ketone stream, and subjecting the ketone stream to both hydrodeoxygenation and to hydroisomerisation reaction conditions, to yield a deoxygenated and isomerised base oil product stream containing the renewable base oil.

Abstract: Compositions corresponding to marine diesel fuels, fuel oils, jet fuels, and/or blending components thereof are provided that include at least a portion of a natural gas condensate fraction. Natural gas condensate fractions derived from a natural gas condensate with sufficiently low API gravity can provide a source of low sulfur, low pour point blend stock for formation of marine diesel and/or fuel oil fractions. Natural gas condensate fractions can provide these advantages and/or other advantages without requiring prior hydroprocessing and/or cracking.

Abstract: The present invention provides a blended fuel and methods for producing the blended fuel, wherein a low carbon fuel derived from a renewable resource such as biomass, is blended with a traditional, petroleum derived fuel. A blended fuel which includes greater than 10% by volume of low carbon fuel has an overall improved lifecycle greenhouse gas content of about 5% or more compared to the petroleum derived fuel. Also, blending of the low carbon fuel to the traditional, petroleum fuel improves various engine performance characteristics of the traditional fuel.

Abstract: Deasphalter rock from high lift deasphalting can be combined with a flux to form a fuel oil blending component. The high lift deasphalting can correspond to solvent deasphalting to produce a yield of deasphalted oil of at least 50 wt %, or at least 65 wt %, or at least 75 wt %. The feed used for the solvent deasphalting can be a resid-containing feed. The resulting fuel oil blendstock made by fluxing of high lift deasphalter rock can have unexpectedly beneficial properties when used as a blendstock.

The composition includes at least about 98 wt % C7-C12 n-paraffins, where at least about 10 wt % of composition includes n-decane, at least about 20 wt % of the composition includes n-dodecane, and at least about 75 wt % of the composition includes even carbon number paraffins. The composition also includes less about 0.1 wt % oxygenates and less than about 0.1 wt % aromatics.

Abstract: A process and plant for the thermocatalytic conversion of waste materials into reusable fuels and a fuel produced by the process, involving the steps of delivering melted waste material to one or more pyrolysis chambers via heated and valved manifolds and effecting pyrolysis of the waste material into a gaseous state in an oxygen purged and pressure controlled environment. Pyrolytic gases are then transferred to a catalytic converter where the molecular structure of the gaseous material is altered in structure and form, with gases then transferred to one or more condensers to distil and cool gases in to their respective fractions. After post pyrolysis treatment, fuel fractions form a useable fuel.
