摘要： Furfural is produced by contacting an aqueous feedstock solution containing C5 sugar and/or C6 sugar using a soluble acid catalyst with reactive distillation. Both high yield and high conversion are obtained in the reaction vessel. Degradation of furfural is minimized by its low residence time in contact with the acid catalyst. The use of staged distillation improves the furfural yield.

摘要： Furfural is produced by mixing an aqueous feedstock solution containing C5 sugar and/or C6 sugar with a heated, high boiling, water-miscible solvent, such as sulfolane, and a soluble acid catalyst. Furfural product and water are distilled off through a multistage distillation column, leaving non-volatile solvent behind. Typical furfural yields with sulfolane as the reaction solvent are about 80% at as high as 99% conversion. Also, certain by-products (e.g., humins) solubilized in the reaction solvent can be precipitated by addition of water or aqueous feedstock solution and then removed by filtration, thereby providing a convenient and effective way of removing these undesirable byproducts from the reaction mixture.

摘要： 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.

摘要： Furfural is produced in one step at both high yield and high conversion from a feedstock comprising solid biomass and/or insoluble polysaccharide, in a high boiling, water-miscible solvent containing a soluble acid catalyst, and water. Furfural product and water can be distilled off, leaving non-volatile solvent behind. Because furfural contact with the acidic medium is minimized, degradation is kept to a minimum. The feedstock does not have to be pretreated. Because the biomass undergoes near complete dissolution, the residual material is flowable and easier to handle than residual solids reported from other processes. Further, certain by-products (e.g., humins, lignins) solubilized in the reaction solvent can be precipitated by addition of water or aqueous solution and then removed from the reaction mixture.

摘要： 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.
