Cellulose Ester Compositions Derived From Recycled Plastic Content Syngas

A process for preparing a recycle cellulose ester and a recycle cellulose ester composition and articles made with such recycle cellulose esters comprising at least one cellulose ester having at least one substituent on an anhydroglucose unit (AU) derived from recycled plastic content syngas are provided. The recycled plastic content syngas can be obtained by gasifying feedstocks containing a solid fossil fuel such as coal, a plastic, and water. The plastic can be post-consumer or postindustrial plastic.

2 Independent Claims

  • Independent Claim 1. A process for preparing a recycle cellulose ester (Recycle CE) comprising: (1) preparing a recycled plastic content syngas in a synthesis gas operation by gasifying a feedstock containing a solid fossil fuel source and at least some content of recycled plastics(2) using the recycled plastic content syngas as a feedstock in a reaction scheme to produce at least one cellulose reactant for preparing a Recycle CEand (3) reacting said at least one cellulose reactant to prepare at least one Recycle CE.

  • Independent Claim 13. An integrated process for preparing a Recycle CE which comprises the processing steps of: (1) preparing a recycled plastic content syngas in a synthesis gas operation utilizing a feedstock that contains a solid fossil fuel source and at least some content of recycled plastics(2) preparing at least one chemical intermediate from said syngas(3) reacting said chemical intermediate in a reaction scheme to prepare at least one cellulose reactant for preparing a Recycle CE, and/or selecting said chemical intermediate to be at least one cellulose reactant for preparing a Recycle CEand (4) reacting said at least one cellulose reactant to prepare said Recycle CEwherein said Recycle CE comprises at least one substituent on an anhydroglucose unit (AGU) derived from recycled plastic content syngas.
