Abstract: A method of producing a fuel additive includes producing a first product stream comprising butadiene by passing a feed stream comprising C4 hydrocarbons through a steam cracker; transforming greater than or equal to 90 weight % of the butadiene in the first product stream into a second product stream by passing the first product stream through a first hydrogenation unit, wherein the second product stream comprises 1-butene, 2-butene, n-butane, isobutylene, isobutane, or a combination thereof; and converting the second product stream into the fuel additive by passing the second product stream through a fuel additive synthesis unit with an acid catalyst.

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: A fuel additive formulation, method of use, and method of producing the fuel additive formulation are described. The fuel additive of the present disclosure comprises a mixture of nitroparaffins comprising nitropropane and nitromethane, a lubricant, and an aromatic hydrocarbon. The fuel additive formulation is substantially free of nitroethane. The combustion in an internal combustion engine of a fuel containing the additive results in reduced emissions relative to the combustion of a fuel not containing the additive.

Abstract: The present invention relates to a process for the purification of biological feed material and to a process for catalytically converting the purified biological feed material into hydrocarbons suitable as biofuel components. The purified feed material is treated in a reactor system including a catalytically active guard bed phase and a catalytically active main reaction phase. At least one of the phases includes a catalyst bed with a combination of hydrodeoxygenating (HDO) and hydrodewaxing (HDW) catalysts. The process provides biofuel with acceptable ignition and cold flow properties.
