摘要:The present disclosure provides recombinant microorganisms and methods for the production of 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA from a carbon source. The method provides for engineered microorganisms that express endogenous and/or exogenous nucleic acid molecules that catalyze the conversion of a carbon source into 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA. The disclosure further provides methods of producing polymers derived from 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA.

权利人:UNIV BRIGHAM YOUNG
摘要:Methods are described for making a texturized catalyst. The textural promoter may be a high-surface area, high-porosity, stable metal oxide support. The catalyst is manufactured by reacting catalyst precursor materials and support materials in a single, solvent deficient reaction to form a catalyst. The catalyst may be particles or a coating or partial coating of a support surface.
