Abstract
A recycle content oxo glycol and method of making a recycle content oxo glycol wherein the recycle content is derived directly or indirectly from the cracking of recycle content pyrolysis oil and/or gas. The cracking of the pyrolysis oil can be conducted in a gas furnace or a split furnace.
Claims20
A method of making a recycle content 2,2 substituted 1,3-propane diol composition (“r-OG”), said method comprising hydroformylating a recycle content olefin composition at least a portion of which is derived directly or indirectly from pyrolyzing a recycled waste with syngas to form a recycle content aldehyde (r-AD) and then reacting at least a portion of the r-AD in the presence of a catalyst to produce a glycol effluent comprising (“r-OG”)m, the method comprising:
- a pyrolyzing a pyrolysis feed comprising a recycled waste material to thereby form a pyrolysis effluent comprising recycle pyoil (r-pyoil) and/or a recycle pygas (“r-pygas”);
- b. cracking a cracker feed comprising at least a portion of the r-pyoil to thereby produce a cracker effluent comprising r-olefins;
- c. reacting the r-olefin volume in a synthetic process to make the recycle content aldehyde (r-AD);
- d. reacting at least a portion of the recycle content aldehyde (r-AD) in a synthetic process to make the recycle content 2,2 substituted 1,3-propane diol composition;
- and
- e. applying a recycle content value to at least a portion of said 2,2 substituted 1,3-propane dio composition based on feeding a pyrolysis recycle content oilefin (“pr-olefin”) or recycle aldehyde composition (“pr-AD”) as a feedstock.
A method of making oxo glycol, said method comprising:
- a. an oxo glycol manufacturer obtaining an olefin or an aldehyde composition from a supplier and either:
- i. from said supplier, also obtaining a pyrolysis recycle content allotment or
- ii. from any person or entity, obtaining a pyrolysis recycle content allotment without a supply of an olefin or aldehyde composition from said person or entity transferring said pyrolysis recycle content allotment;
- and
- b. said oxo glycol manufacturer making an oxo glycol composition (“OG”) from any olefin or aldehyde composition obtained from any source;
- and
- c. either:
- i. applying said pyrolysis recycle content allotment to OG made by the supply of olefin or aldehyde obtained in step (a);
- or
- ii. applying said pyrolysis recycle content allotment to OG not made by the supply of olefin or aldehyde obtained in step (a), or
- iii. depositing said pyrolysis recycle content allotment into a recycle inventory from which is deducted a recycle content value and applying at least a portion of said value to:
- 1. OG to thereby obtain r-OG, or
- 2. to a compound or composition other than OG, or
- 3. both, wherein the pyrolysis recycle content allotment is a pyrolysis recycle content value that is an allocation or a credit;
- whether or not the recycle content value is obtained from a pyrolysis recycle content allotment obtained in step a (i) or step a (ii).
A method of making a recycle content oxo glycol composition (“r-OG”), said method comprising:
- a. reacting any olefin or aldehyde composition in a synthetic process to make an oxo glycol composition (“OG”);
- and
- b. applying a recycle content value to at least a portion of said OG to thereby obtain a recycle content oxo glycol composition (“r-OG”);
- and
- c. obtaining said recycle content value by deducting at least a portion of said recycle content value from a recycle inventory, further optionally said recycle inventory also containing a pyrolysis recycle content allotment or a pyrolysis recycle content allotment deposit having been made into the recycle inventory prior to the deduction, wherein the pyrolysis recycle content allotment is a pyrolysis recycle content value that is an allocation or a credit;
- and
- d. optionally communicating to a third party that said r-OG has recycle content or is obtained or derived from recycled waste.
