Abstract: A process for preparing 5-(alkoxycarbonyl)furan-2-carboxylic acids (ACFC) by oxidizing various furcates in the presence of a catalyst containing cobalt, manganese, and bromine, and a solvent while simultaneously removing water vapor from the reaction chamber. The process can produce ACFC with high purity and low color, and in high yield.
Abstract: Processes and systems for making recycle content hydrocarbons, including olefins, are provided that integrate a cracker unit with one or more other processing units. For example, in some cases, a fluidized catalytic cracking unit may be used to crack recycle content pyrolysis oil and the effluent from the FCC may be further processed in a conventional cracker unit, including its downstream separation zone, to provide recycle content hydrocarbon product stream. In other cases, a pyrolysis unit and cracking unit may be co-located and may share at least one utility, service group, boundary, conduit, energy exchange zone, and/or geographical area.

Abstract: Copolyesters made from the direct esterification of terephthalic acid with diols including ethylene glycol, but which contain low diethylene glycol (DEG) content, and processes for making the copolyesters. The copolyesters are characterized by comprising 1.0 wt % or less of DEG without requiring the use of DEG-suppressing additives. The processes are characterized by features including operating at lower pressures and lower EG:TPA feed mole ratios in the first reaction zone, while simultaneously at higher temperatures than typical operation in order to lower incorporation of DEG into the final polymer.
