Waste plastics are an abundant feedstock for the production of renewable chemicals. Pyrolysis of waste plastics produces pyrolysis oils with high concentrations of olefins (>50% nyhav). Kev lag luam petrochemical ib txwm siv ntau lub zog siv cov kauj ruam los tsim olefins los ntawm fossil feedstocks xws li naphtha, natural gas, thiab crude oil. Hauv kev ua haujlwm no, peb pom tau tias cov roj pyrolysis tuaj yeem siv los tsim aldehydes los ntawm hydroformylation, ua kom zoo dua ntawm olefin functionality. Cov aldehydes no tuaj yeem raug txo mus rau mono- thiab dialcohols, oxidized rau mono- thiab dicarboxylic acids, los yog aminated rau mono- thiab diamines los ntawm kev siv homogeneous thiab heterogeneous catalysis. Txoj kev no tsim cov tshuaj muaj txiaj ntsig zoo oxygenated los ntawm tus nqi qis tom qab cov neeg siv khoom siv dua polyethylene. Peb npaj siab tias cov tshuaj uas tsim los ntawm txoj kev no tuaj yeem txo qis cov pa hluav taws xob hauv tsev cog khoom ~ 60 feem pua piv nrog lawv cov khoom tsim los ntawm cov khoom siv roj av.
