Abstract

A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content oxo alcohol or oxo plasticizer or by deducting from a recycle inventory a recycle content value applied to an oxo alcohol or oxo plasticizer composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an oxo alcohol or oxo plasticizer manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

Claims (7)

1 . A method of making a recycle content oxo alcohol composition (“r-OA”), said method comprising (i) hydroformylating a recycle content olefin composition, at least a portion of which is derived directly or indirectly from pyrolyzing a recycled plastic waste, with syngas to form a recycle content aldehyde (r-aldehyde), wherein at least a portion of the recycle content olefin composition is obtained from the steam cracking of a cracker feed composition comprising a combination of r-pyoil and a non-recycle hydrocarbon stream, and (ii) hydrogenating at least a portion of the r-aldehyde to produce an oxo alcohol effluent comprising r-oxo alcohol (“r-OA”).

2 . The method of claim 1 , wherein, wherein the r-olefin is obtained from the steam cracking of a cracker feed comprising (a) at least 1 weight percent of r-pyoil and (b) at least 60 weight percent of a non-recycle hydrocarbon stream comprising ethane, propane, and/or natural gasoline.

3 . A method of making a recycle content oxo alcohol composition (“r-oxo alcohol”), said method comprising:

a. reacting any olefin or aldehyde composition in a synthetic process to make an oxo alcohol composition (“OA”); and

b. applying a recycle content value to at least a portion of said oxo alcohol to thereby obtain a recycle content oxo alcohol composition (“r-OA”);

wherein said recycle content value is obtained by either (a) by deducting at least a portion of said recycle content value from a recycle content inventory, or (b) by a method comprising (i) hydroformylating a recycle content olefin composition, at least a portion of which is derived directly or indirectly from pyrolyzing a recycled plastic waste, with syngas to form a recycle content aldehyde (r-aldehyde), wherein the recycle content olefin composition is obtained from the steam cracking of a cracker feed comprising a combination of r-pyoil and a non-recycle hydrocarbon stream, and (ii) hydrogenating at least a portion of the r-aldehyde to produce an oxo alcohol effluent comprising r-oxo alcohol (“r-OA”); and

c. communicating to a third party that said r-oxo alcohol has recycle content or is obtained or derived from recycled waste.
