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.
(canceled)
A process of making a densified textile derived polymer reactant, comprising making a densified textile derived syngas, and reacting said densified textile derived syngas to make the densified textile derived polymer reactant optionally through one or more densified textile derived chemical intermediates.
3-60. (canceled)
A cellulose ester obtained directly or indirectly from a process for making a densified textile derived syngas.
A densified textile derived cellulose ester that is synthesized from (i) a raw material that is sustainable, and (ii) a raw material at least a portion of which is obtained, through one or more intermediate steps, from recycled textiles, wherein the densified textile derived cellulose ester is biodegradable.
