A renewable fuel blend and a process for producing a renewable fuel blend are described. The blend includes biologically derived Cto Cnormal paraffins, which are provided to the blend in quantities such that blend does not require a pour point reducing treatment to achieve a low pour point. In embodiments, the normal paraffins are produced in an upgrading process, such as a hydrotreating process.

Low pour point renewable fuel blend

Trace amount levels of heavy metals such as mercury in crude oil are reduced by contacting the crude oil with a sufficient amount of a reducing agent to convert at least a portion of the non-volatile mercury into a volatile form of mercury, which can be subsequently removed by any of stripping, scrubbing, adsorption, and combinations thereof. In one embodiment, at least 50% of the mercury is removed. In another embodiment, the removal rate is at least 99%. In one embodiment, the reducing agent is selected from sulfur compounds containing at least one sulfur atom having an oxidation state less than +6; ferrous compounds; stannous compounds; oxalates; cuprous compounds; organic acids which decompose to form COand/or Hupon heating; hydroxylamine compounds; hydrazine compounds; sodium borohydride; diisobutylaluminium hydride; thiourea; transition metal halides; and mixtures thereof.

The present invention is generally directed to novel biodiesel fuel compositions having enhanced low-temperature properties. The present invention is additionally directed to methods (i.e., processes) for making such enhanced biodiesel fuels by improving the low-temperature properties of ester-based biodiesel fuels via in situ enhancement and/or additive enhancement.

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.

Methods for improving low-temperature properties of biodiesel fuel

A lubricating oil composition comprising (a) a major amount of a base oil of lubricating viscosity and (b) a minor deposit-inhibiting effective amount of a reaction product prepared by transesterifying at least one glycerol ester and at least one non-glycerol polyol ester is provided. Methods for its use are also provided.

Engine oil compositions

A lubricating base oil composition is provided comprising (a) at least one Fischer-Tropsch derived lubricating base oil characterized as having a kinematic viscosity of about 2 to about 5 centistoke (cSt) at 100&#xb0; C.; and (b) at least one polyol ester. Methods for improving the fuel economy of an internal combustion engine are also provided.

A method is described to determine the valve train wear performance of a lubricating oil by adding to the lubricating oil from about 2% to about 9% by weight, based on the total weight of the lubricating oil, of a mixture of at least three carbon black components of mixed particle size and measuring the wear induced in a wear test.
