Abstract: The present disclosure relates to a method including subjecting an organic stream comprising at least one oxygenate to hydrotreatment, whereby a hydrotreatment product comprising ethylbenzene is produced, wherein the organic stream is a product of a process for the production of propylene oxide; and separating an ethylbenzene product stream from the hydrotreatment product, to yield a residual stream.

Abstract: A process for producing furan dicarboxylic acid or an ester thereof from a feedstock comprising hydroxymethyl furfural (HMF) and humins is disclosed. Humins are a byproduct from reactions forming HMF from sugars and are typically removed from the HMF prior to any further processing. A humins-containing HMF feedstock is utilized to produce furan dicarboxylic acids and ester substantially free from humins.

Abstract: A process for efficiently esterifying furan dicarboxylic acid, especially 2,5-furan dicarboxylic acid in the presence of an alcohol and, optionally, a catalyst is disclosed. The process provides high yields of the diesters of furan dicarboxylic acid and comprises a multi-stage esterification process wherein a portion of a gas phase is removed at each stage of the multi-stage process.

Abstract: Furfural is produced by contacting a feedstock solution containing C5 sugar and/or C6 sugar with a solid acid catalyst using reactive distillation. Both high yield and high conversion are obtained, without production of insoluble char in the reaction vessel. Degradation of furfural is minimized by its low residence time in contact with the solid acid catalyst. Higher catalyst lifetime can be achieved because the catalyst is continually washed with the refluxing aqueous solution and not sitting in high-boiling byproducts like humins, which are known to be deleterious to catalyst lifetime.
