Abstract: A process for upgrading a hydrocarbon feed includes contacting the hydrocarbon feed with hydrogen in the presence of a ring opening catalyst in a naphthene conversion unit, the contacting causing naphthenes in the hydrocarbon feed to react to produce a converted effluent comprising isoparaffins and normal paraffins. The process includes separating the converted effluent in a paraffin separation system to produce an isoparaffin-rich stream and an n-paraffin-rich stream. The process includes contacting the isoparaffin-rich stream with hydrogen in the presence of an isomerization catalyst in a reverse isomerization unit, the contacting causing isomerization to produce an isomerate comprising an equilibrium mixture of normal paraffins and isoparaffins. The process include separating the isomerate in the paraffin separation system to produce the isoparaffin-rich stream and the n-paraffin-rich stream, and passing the n-paraffin-rich stream to a steam cracker to produce a cracker effluent comprising olefins.
Abstract: The invention relates to a method for the manufacture of a combustible material having a lower heating value of 5.29 MWh/t or more.

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: Systems and methods to provide low carbon intensity (CI) ethanol through one or more targeted reductions of carbon emissions based upon an analysis of carbon emissions associated with a combination of various options for feedstock procurement, feedstock refining, processing, or transformation, and ethanol distribution pathways to end users. Such options are selected to maintain the total CI (carbon emissions per unit energy) of the ethanol below a pre-selected threshold that defines an upper limit of CI for the ethanol.

Abstract: In one embodiment, thermite matches are provided. For instance, thermite matches as described herein may be constructed as a multi-staged formulation comprising an outer ignition tip, an optional inner transition tip, and a bulk fuel thermite stage. The outer ignition tip may comprise an ignition compound that can be struck/scraped against an abrasive counter-chemical surface (e.g., red phosphorous) to initiate the reaction. The outer ignition tip can reach a first burn temperature that can further ignite the inner transition tip stage, which can in turn burn at a temperature that reaches the ignition temperature of the bulk fuel thermite. The high burn temperature of the thermite match may then be used to ignite other materials, such as hard-to-ignite materials, such as a thermite rod for cutting or welding. Other embodiments provide for thermite match handles and a two-piece ignition thermite matches.

Abstract: Fuel oil compositions, and methods for blending such fuel oil compositions, to enhance initial compatibility and longer term stability when such fuel oil compositions are blended to meet IMO 2020 low sulfur fuel oil requirements (ISO 8217). In one or more embodiments, asphaltenic resid base stocks are blended with high aromatic slurry oil to facilitate initial compatibility such that low sulfur cutter stocks, e.g., vacuum gas oil and/or cycle oil, may be further blended therein to cut sulfur content while maintaining longer term stability. These fuel oil compositions are economically advantageous when used as marine low sulfur fuel oils because greater concentrations of high viscosity resids are present in the final blend.
