Abstract: The presently disclosed subject matter provides methods for producing olefins and/or aromatics from coker naphtha. In a non-limiting embodiment, a method for producing aromatics includes hydrogenating the coker naphtha stream in the presence of a first catalyst to remove diolefins and sulfur, if any, to obtain a hydrogenated stream and subjecting the hydrogenated stream to aromatization in the presence of a second catalyst to produce an aromatic-rich stream that includes benzene, toluene and xylene. In certain embodiments, a method for producing olefins includes hydrogenating the coker naphtha stream in the presence of a first catalyst to remove diolefins and sulfur, if any, to obtain a hydrogenated stream and subjecting the hydrogenated stream to catalytic cracking in the presence of a second catalyst to produce an olefin-rich stream that includes ethylene, propylene and aromatics.

Abstract: Methods and systems for producing olefins and aromatics are provided. Methods can include removing silica from the coker naphtha feedstock to produce a first effluent, hydrogenating the first effluent to produce a second effluent, reacting the second effluent to produce a third effluent comprising aromatics, a fourth effluent comprising olefins, and a fifth effluent, separating the fourth effluent to produce a propylene product stream, an ethylene product stream, and a sixth effluent, recycling the sixth effluent by combining it with the second effluent.

Abstract: An umbrella holder for supporting an umbrella pole on a backpack strap so that the wearer of the backpack can be in a hands-free condition while the umbrella is deployed. The device includes a first panel, a second panel, a third panel, a pair of thumb screws and a panel closure member. The first panel is hinged to the second panel. The second panel is hinged to the third panel. The first and second panels create a retaining space for a backpack strap. The second and third panels create a retaining space for an umbrella pole. The thumb screws are hinge and tightened to secure a backpack strap. The second and third panels are held together by the panel closure member which is attached by a hinge to the first panel. A preferred embodiment includes rubber cushion members to securely hold umbrella poles of varying diameters.

Abstract: Polymer systems comprising poly(vinyl chloride), a non-petroleum based filler, and a polyester additive, wherein the polymer system is highly filled, and articles made therefrom, are described. The high loading of filler (e.g., talc, calcium carbonate or a combination thereof) is achieved by incorporation of polyester additives such as polyhydroxyalkanoates. High filler loading without significant reduction of relevant material properties can be associated with cost savings and environmental benefits.

Abstract: By way of an introductory example, the system may communicate a display interface comprising a plurality of prioritized component information for a supply chain. The system may acquire priority models associated with respective priority factors that are used to prioritize the component information. Each of the priority models may be configured to process information based on the respective priority factors. The system may further acquire selection criteria associated with the component identifier. The system may select, based on the selection criteria, the priority models that are relevant to prioritizing the component identifier. The system may determine an updated priority metric for the component identifier by applying production information to the selected priority models.
