USPTO Patent Grant US12583831B2 for Hydrogenation Processes
Summary
The USPTO has granted patent US12583831B2 to Archer-Daniels-Midland Company for selective hydrogenation processes and catalysts. The patent covers methods for upgrading impure feedstocks, such as those derived from biomass, to increase the concentration of valuable intermediates like glycolaldehyde and hydroxyacetone.
What changed
USPTO patent grant US12583831B2 has been issued to Archer-Daniels-Midland Company, covering novel processes and catalysts for the selective hydrogenation of compounds with carbonyl carbon atoms. The patent specifically addresses methods to upgrade impure feedstocks, particularly those derived from biomass, to enhance the concentration of desired intermediates like glycolaldehyde and hydroxyacetone without over-hydrogenation. The disclosed technology utilizes noble metal catalysts, such as Ruthenium (Ru) and Platinum (Pt), to achieve this selectivity.
This patent grant represents a new intellectual property protection for specific chemical processes. While it does not impose direct compliance obligations on other entities, it may influence research and development strategies, licensing opportunities, and competitive landscapes within the chemical and pharmaceutical manufacturing sectors. Companies operating in related fields should be aware of this patented technology, particularly if their processes involve biomass conversion or selective hydrogenation of carbonyl compounds.

Processes and cataylsts for the selective hydrogenation of compounds having carbonyl carbon atoms

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.
