Abstract: Processes and systems for making recycle content hydrocarbons, including olefins, from recycled waste material. Recycle waste material may be pyrolyzed to form recycle content pyrolysis oil composition (r-pyoil), at least a portion of which may then be cracked to form a recycle content olefin composition (r-olefin). In some cases, the pyrolysis and cracking may be carried out in different sections of the same furnace, or in different furnaces in the same cracker facility. Pyrolysis conducted in a furnace may or may not require retrofitting a furnace previously used to crack alkanes to form olefins.

Abstract: Formaldehyde is a common component of antimicrobial compositions for preserving animal feeds. However, the use of formaldehyde is coming under pressure and alternative antimicrobial compositions are needed. The present application discloses methods and/or uses of a formaldehyde-free antimicrobial composition comprising formic acid and propionic acid in the making of rendered animal protein compositions or in the inhibiting of the development of Salmonella bacteria in animal by-product compositions (e.g., rendered animal proteins) while maintaining higher protein digestibility comparing with formaldehyde.

Abstract: Recycled content oxo products are produced using a process and system that applies physical and/or credit-based recycled content from one or more feed materials to the oxo products produced from the feed materials.

Abstract: A predominantly C2 to C4 hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to a first coil while a second cracker feed with none of the r-pyoil or less of the r-pyoil is fed to a second coil, and both are cracked in a cracker furnace to form an olefin-containing effluent stream. Alternatively, the r-pyoil can be fed and distributed across multiple coils along with the non-recycle cracker feed. The furnace can be a gas fed furnace, or split cracker furnace. Further, a first cracker stream with r-pyoil in a first coil can have a lower total molar flow rate than a second cracker stream in a second coil in the same furnace.

Abstract: The present invention provides a non-phthalate, highly sustainable plasticizer, with performance comparable to or better than the existing orthophthalate market leader (DINP) and non-phthalate market leader (DOTP) at a lower cost position. The novel plasticizers are terephthalate ester and epoxidized oil compositions and dibenzoate ester and epoxidized oil compositions. The novel plasticizer compositions are produced by blending a fast fusing terephthalate diester or dibenzoate ester with an epoxidized oil. The presence of the terephthalate diester or the dibenzoate ester in the blend imparts better physical properties and performance properties over the ester or epoxidized oil components alone.

Abstract: The present application discloses regioselectively substituted cellulose esters, films made from the regioselectively substituted cellulose esters and methods for making the same.

Abstract: Regioselectively substituted cellulose esters having a plurality of pivaloyl substituents and a plurality of aryl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in films, such as +A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.

For instance, some embodiments improve the accuracy of these technologies by generating, via a computer model, an estimate of a fluid life for a heat transfer fluid and/or a score that indicates a quality of the heat transfer fluid, among other things. Additional embodiments also improve human-computer interaction, user interfaces, and computer resource consumption relative to existing technologies.

Abstract: Methods and systems for separating mixed plastic waste are provided herein. The methods generally comprise separating the mixed plastic waste into a PET-enriched stream and one or more PET-depleted streams.
