  • Publication number: 20250059128
    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.

  • Publication number: 20250052604
    Abstract: A volume measurement method includes: receiving multiple pulse signals when a device under test (DUT) starts passing through a sensing gate; recording multiple X-axis values corresponding to multiple positions of the DUT in response to each pulse signal, and reading the multiple sensing data to calculate a Y-axis value and a Z-axis value corresponding to each X-axis value, wherein the multiple sensing data is obtained by sensing the DUT through the sensing gate; recording a maximum X-axis value corresponding to a final position of the DUT in response to a final pulse signal when the DUT finishes passing through the sensing gate; setting the maximum of the multiple Y-axis values corresponding to the multiple X-axis values as a maximum Y-axis value, and setting the maximum of the multiple Z-axis values corresponding to the multiple X-axis values as a maximum Z-axis value; and calculating a volume of the DUT based on the maximum X-axis value, the maximum Y-axis value and the maximum Z-axis value.

  • Publication number: 20240368100
    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.
