Abstract: A process and system for recovering a recycle content carbon dioxide is provided that can lower the carbon footprint and global warming potential of a chemical recycling facility. More particularly, a pyrolysis gas from waste plastic pyrolysis may be treated in an absorber system to thereby form a recovered CO2 stream comprising recycle content carbon dioxide. Thus, the global warming potential of the chemical recycling facility may be optimized and lowered due to the carbon dioxide recovery process and system herein.

Abstract: Recycle content pyoil is cracked in a cracker furnace to make olefins and the coil outlet temperature of the r-pyoil fed coils can be lowered by adding r-pyoil to the cracker feedstock, or alternatively, the coil outlet temperature of the r-pyoil fed tubes can rise if the mass flow rates of the combined cracker stream containing r-pyoil are kept the same or lowered. Further, increasing the hydrocarbon mass flow rate by addition of r-pyoil can be achieved to also increase the output of ethylene and propylene in the cracker effluent. The cracker furnace can accept ethane and/or propane feedstocks in vapor form along with a liquid and/or vapor feed of r-pyoil.

Abstract: Provided is a process for preparing bicyclo[2.2.2]octane-1,4-diol starting from cyclohexane-1,4-dione. The dione is reacted with certain trialkylsilyl halides or trimethylsilyl trifluormethanesulfonate in the presence of a non-nucleophilic base to afford a silyl-substituted diene, which is in turn reacted with ethylene and subsequently reduced to provide the title compound.

Abstract: The invention provides a process for the preparation of a modified triethanolamine/fatty acid ester composition ratio by treatment of a conventional triethanolamine fatty acid ester composition with a hydrolytic enzyme. Also provided are novel mixtures of triethanolamine and mono-, di-, and tri-esters of fatty acids which are useful in the preparation of cationic surfactants useful in fabric softening applications. In one aspect, the method increases the triester fraction without significantly affecting the amount of mono-ester and unesterified species, which in turn adds to the flexibility in the formulation of the corresponding fabric softening compositions.
