  • Patent number: 11958751
    Abstract: Methods are disclosed for synthesizing materials, including an initial synthesis in the presence of WS-ODSO (which can include a pH-modified WS-ODSO composition, in certain embodiments a neutralized WS-ODSO composition), and one or more subsequent syntheses using supernatant (“mother liquor”) from a previous synthesis of the same or different materials. The synthesized materials in the initial synthesis and in subsequent synthesis can be the same or different inorganic oxide materials including amorphous oxides, crystalline oxides or oxides of metals. The methods advantageously reduce the amount of utility water required for synthesizing a material and reduce the water waste, and reduce the DSO waste from a refinery and discharge into the environment. In certain embodiments the methods reduce the requirements to procure an alkaline reagent required for synthesizing materials. In certain embodiments, supernatant can be recycled over multiple synthesis batches of the same or different type of material.

  • Patent number: 11920093
    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.
