摘要： A polypropylene composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content polypropylene or by deducting from a recycle inventory a recycle content value applied to a polypropylene composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a polypropylene manufacturer has its origin in recycled waste plastics.

摘要： A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content glycol ester by deducting from a recycle inventory a recycle content value applied to a glycol ester composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a glycol ester manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

摘要： A process for producing recycle polyesters made from organic compounds, e.g., acids and alcohols, derived from recycled, reused or other environmentally favored raw materials by obtaining a recycle monomer composition derived directly or indirectly from cracking a recycle content pyrolysis oil composition and reacting the recycle monomer with recycle DMT obtained directly or indirectly from the depolymerization of terephthalate polyesters to prepare a recycle polyester.

摘要： A recycle content ethylene is fed to a reactor to make propionaldehyde having recycle content. The recycle ethylene feedstock is derived directly or indirectly from the cracking of recycle content pyrolysis oil. The cracking of the pyrolysis oil can be conducted in a gas furnace or a split furnace.

摘要： Pre-ground plastics of small particle size not more than 2 mm are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. High solids concentrations in the feedstock stream can be obtained without significant impact on the feedstock stream stability and pumpability. A consistent quality of syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The subsequent syngas produced from this material can be used to produce a wide range of chemicals.

摘要： Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of densified textile derived syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The densified textile derived syngas quality, composition, and throughput are suitable for produce a wide range of chemicals and polymers, including methanol, acetic acid, methyl acetate, acetic anhydride, and cellulose esters through a variety of reaction schemes in which at least a portion of the chemical or polymer originates with densified textile derived syngas.
