Method for making aldehydes, alcohols, amides, and carboxylic acids from plastic pyrolysis oil

A method to make primary alcohols, di-alcohols, or esters from plastic waste, the method comprising:

• (a) providing pyrolysis oil and separating the pyrolysis oil into a light cut having a boiling point less than about 175° C. and a heavy cut having a boiling point greater than about 175° C., where the light cut and the heavy cut comprise olefins;
• (b) hydroformylating the light cut and/or the heavy cut, independently, wherein at least a portion of the olefins in the light cut and/or the heavy cut are converted to aldehydes, to yield corresponding light and/or heavy mixtures comprising aldehydes;
• (c) separately hydrogenating the light mixture and/or the heavy mixture of step (b) to yield corresponding product mixture(s) comprising a product selected from the group consisting of primary alcohols, di-alcohols, esters, and combinations thereof.
