Abstract: Unleaded aviation gasoline. An aviation gasoline fuel blend includes an unleaded aviation gasoline base fuel, with an effective amount of selected alkyl benzenes to improve the functional engine performance to avoid harmful detonation sufficient to meet or exceed selected standards for detonation performance requirements in full scale aircraft piston spark ignition engines designed for use with Grade 100LL avgas. Suitable alkylated benzenes may include a mixture of xylene isomers. Aromatic amines, such as m-toluidine, may also be added to increase MON. Base fuels may be a high quality aviation alkylate, or may be a commercial iso-octane, or a mixture of high quality aviation alkylate enhanced by iso-octane, or by commercial iso-octane mixtures, and may include iso-pentane or butane or both iso-pentane and butane in sufficient quantity to provide appropriate vapor pressure for the final fuel blend.

Abstract: A method of producing liquid fuel and/or chemicals from a carbonaceous material entails combusting a conditioned syngas in pulse combustion heat exchangers of a steam reformer to help convert carbonaceous material into first reactor product gas which includes carbon monoxide, hydrogen, carbon dioxide and other gases. A portion of the first reactor product gas is transferred to a hydrogen reformer into which additional conditioned syngas is added and a reaction carried out to produce an improved syngas. The improved syngas is then subject to one or more gas clean-up steps to form a new conditioned syngas. A portion of the new conditioned syngas is recycled to be used as the conditioned syngas in the pulse combustion heat exchangers and in the hydrocarbon reformer. A system for carrying out the method include, a steam reformer, a hydrocarbon reformer, first and second gas-cleanup systems, a synthesis system and an upgrading system.

Abstract: Processes for using pyrolysis gas as a feedstock or a co-feedstock for making a variety of chemicals, for example, circular ethylene, circular ethylene polymers and copolymers, and other circular products. In these processes, pyrolysis reactor conditions can be selected to increase or optimized the production of pyrolysis gas over pyrolysis oil, and the pyrolysis gas which is usually used as fuel or flared can be fed downstream of the steam cracker furnace for economic use to form circular chemicals. Operating parameters of the pyrolysis unit may be adjusted to increase or decrease the proportion of pyrolysis gas relative to pyrolysis liquid as a function of their relative economic values.

Abstract: A method of producing one or more fuels having a renewable content from a fuel production process that includes one or more processing steps wherein hydrogen is reacted with crude oil derived liquid hydrocarbon, where the hydrogen is produced by a plurality of hydrogen production units based on steam methane reforming. The method includes selecting one or more hydrogen production units from the plurality of hydrogen production units which have one or more hydrogen-producing characteristics, and allocating renewable methane such that a renewable fraction of feedstock for the selected hydrogen production units is greater than a renewable fraction of feedstock for other hydrogen production units. The selected hydrogen production units are selected to increase a yield of renewable content of one or more of the fuels produced by the fuel production process and/or reduce a carbon intensity of such fuels for a given quantity of renewable methane.

Abstract: Low sulfur fuel oil blend compositions and methods of making such blend compositions to increase the stability and compatibility of LSFO blends having paraffinic resids that are blended with distillates and/or cracked stocks of higher asphaltenes and/or aromatics content. In one or more embodiments, distillates and/or cracked stocks that incrementally reduce the initial aromaticity of the distillate or cracked stock with the highest aromaticity are sequentially blended prior to resid addition. Such incremental reduction and sequential blending have been found to provide a resulting low sulfur fuel oil blend that is both compatible and stable.

Abstract: The present disclosure provides a process for forming a biogenic carbon-based fuel or a fuel intermediate from biogenic carbon dioxide and hydrogen. The hydrogen is sourced from a process that produces hydrogen and fossil carbon dioxide from a fossil-fuel hydrocarbon and separates the fossil carbon dioxide from the hydrogen. The process may further comprise carrying out or arranging for one or more parties to carry out at least one step that contributes to a reduction in the GHG emissions of the biogenic carbon-based fuel, or a fuel made from the fuel intermediate, of at least 20% relative to a gasoline baseline. In various embodiments this includes (a) introducing the fossil carbon dioxide underground, and/or (b) using a biogenic carbon-based product selected from a chemical and energy product produced from the non-fossil organic material to displace the use or production of a corresponding fossil-based product.
