Abstract: Selective hydrogenation processes are disclosed that can upgrade impure feeds, such as those obtained from biomass and containing a number of small (e.g., 2-6 carbon atom) molecules having aldehyde and/or ketone carbon atoms. For example, whereas glycolaldehyde and its methylated derivative, hydroxyacetone (acetol) are both high value intermediates for certain downstream processing reactions, they are normally recovered in a condensate from pyrolysis of carbohydrates (e.g., aldose-containing sugars) together with glyoxal and its methylated derivative, pyruvaldehyde. The selective hydrogenation of these compounds bearing two carbonyl carbon atoms, without over-hydrogenation to ethylene glycol and propylene glycol, can increase the concentration of the desired intermediates. These beneficial effects of selective hydrogenation may be achieved through the use of a hydrogenation catalyst comprising noble metals such as Ru and Pt.

Abstract: Disclosed herein are methods for synthesizing useful intermediates and/or products from 1,2,5,6-hexanetetrol (HTO), which itself can be derived from a sugar. In an aspect, a process is provided for production of THFDCA from 1,2,5,6-hexanetetrol (HTO). The process comprises the steps of (a) ring closing to form a ring compound and (b) oxidizing using a catalyst comprising platinum and bismuth to form an acid mixture. Step (a) may be performed before or after step (b).

Abstract: An integrated, co-product capable process is provided for producing taurine in particular with optionally one or both of monoethanolamine and diethanolamine from one or more sugars, comprising pyrolyzing one or more sugars to produce a crude pyrolysis product mixture including glycolaldehyde and formaldehyde; optionally removing formaldehyde from the crude pyrolysis product mixture, then combining the crude pyrolysis product mixture with an aminating agent in the presence of hydrogen and further in the presence of a catalyst to produce at least monoethanolamine from the crude pyrolysis product mixture; optionally recovering diethanolamine from the crude reductive amination product, sulfating at least a portion to all of the monoethanolamine product to produce 2-aminoethyl hydrogen sulfate ester; and sulfonating the 2-aminoethyl hydrogen sulfate ester to produce taurine.

Abstract: Processes are disclosed for the synthesis of an α-amino acid or α-amino acid derivative, from a starting compound or substrate having a carbonyl functional group (C═O), with hydroxy-substituted carbon atoms at alpha (α) and beta (β) positions, relative to the carbonyl functional group. According a particular embodiment, an α-, β-dihydroxy carboxylic acid or carboxylate is dehydrated to form a dicarbonyl intermediate by transformation of the α-hydroxy group to a second carbonyl group (adjacent a carbonyl group of the starting compound) and removal of the β-hydroxy group. The dicarbonyl intermediate is optionally cracked to form a second, in this case cracked, dicarbonyl intermediate having fewer carbon atoms relative to the dicarbonyl intermediate but preserving the first and second carbonyl groups. Either or both of the dicarbonyl intermediate and the cracked dicarbonyl intermediate may be aminated to convert the second carbonyl group to an amino (—NH2) group, for producing the corresponding α-amino acid(s).

Abstract: An improved process for making bioderived propylene glycol from a feed composition including at least one of lactic acid, glycerol, a five carbon sugar, a five carbon sugar alcohol, a six carbon sugar and a six carbon sugar alcohol, wherein production of four carbon and higher diols is reduced by adding base after the initiation of the reaction. In preferred embodiments, the process pH and other process conditions are initially established at targeted values for obtaining the highest conversion for a given catalyst consistent with the production of substantially no pentanediol byproducts in the product mixture, and base is added thereafter to control the process pH proximate to the initially targeted value.

Abstract: A process for regenerating catalysts that have been deactivated or poisoned during hydrogenation of biomass, sugars and polysaccharides is described, in which polymerized species that have agglomerated to catalyst surfaces can be removed by means of washing the catalyst with hot water at subcritical temperatures. A feature of the process regenerates the catalysts in situ, which allows the process to be adapted for used in continuous throughput reactor systems. Also described is a continuous hydrogenation process that incorporated the present regeneration process.

Abstract: Improvements in catalyst systems and associated processes for the conversion of glycolaldehyde to monoethanolamine are disclosed. The catalyst systems exhibit improved selectivity to this desired product and consequently reduced selectivity to byproducts such as diethanolamine and ethylene glycol. These beneficial effects are achieved through the use of acids, and particularly Lewis acids, as co-catalysts of the reductive amination reaction, in conjunction with a hydrogenation catalyst.
