Methods for producing higher alcohols from waste plastic pyrolysis oil and the higher alcohols obtained therefrom

A method for producing a higher alcohol from a waste plastic feedstock, comprising:

• (a) providing a hydrocarbon feed stream comprising a pyrolysis oil feed obtained from pyrolysis of plastic waste, wherein the pyrolysis oil feed comprises at least 20 wt % higher olefins with a carbon number in the range C5-C20, based on its total hydrocarbon content;
• (b) contacting the hydrocarbon feed stream with synthesis gas under hydroformylation conditions in the presence of a hydroformylation catalyst and recovering a hydroformylation product;
• (c) subjecting the hydroformylation product to hydrogenation and/or a distillation to recover a higher alcohol product;
• and
• the method further comprises prior to step (b) one or more of:
• subjecting at least a portion of the hydrocarbon feed stream to a selective reduction of diolefins in the presence of a nickel-containing catalyst;
• contacting at least a portion of the hydrocarbon feed stream with a water solution to thereby at least partially remove water-soluble contaminants;
• and
• contacting at least a portion of the hydrocarbon feed stream with one or more adsorbents suitable to thereby at least partially remove one or more contaminants selected from:
• water, metals, chlorides, nitrogen-containing compounds, oxygenates, and phosphorous-containing compounds.
