Process for purifying crude furan 2,5-dicarboxylic acid using hydrogenation |
| abstract |
A process to produce a dry purified furan-2,5-dicarboxylic acid (FDCA) is described. After oxidation of 5-(hydroxymethyl)furfural (5-HMF), a crude FDCA stream is produced that is fed to a crystallization zone followed by a solid-liquid displacement zone to form a low impurity slurry stream. The solids in the low impurity slurry stream are dissolved in a dissolution zone to produce a hydrogenation feed that is hydrogenated in a hydrogenation reactor to generate a hydrogenated FDCA composition. The hydrogenated FDCA composition is routed to a crystallization zone to form a crystallized produce stream that is separated from liquid in a solid-liquid separation zone to generate a purified wet cake stream containing FDCA that can be dried in a drying zone to generate a dry purified FDCA product stream. |
