  • Patent number: 11612881
    Abstract: A process for preparing a silver-containing catalyst for the oxidation of ethylene to ethylene oxide (EO) including the steps of: providing a support having pores; providing a silver-containing impregnation solution; adding an amount of surfactant to the impregnation solution; contacting the support with the surfactant-containing impregnation solution; and removing at least a portion of the impregnation solution prior to fixing the silver upon the carrier in a manner which preferentially removes impregnation solution not contained in the pores. The use of the surfactant results in improved drainage of the silver impregnation solution from the carrier exteriors during the catalyst synthesis. As a result, the amount of silver-containing impregnation solution necessary for the synthesis of the EO catalyst was reduced by up to 15% without reducing the catalyst performance.

  • Patent number: 11608305
    Abstract: An improved process for the recovery of high-purity ethylene-oxide water feed streams to EO purification and MEG reaction units when both are operating in EO plants that incorporate EO Stripper bypass technology, by installing a second lights stripper to exclusively degasify the diluted EO feed to the MEG reactor, thus permitting the use of additional bypassed (gasified) EO absorbate as the diluent and resulting in a substantial increase in the total amount of EO absorbate that can bypass the EO Stripper.

  • Patent number: 11578048
    Abstract: Processes are disclosed for the synthesis of 2-substituted furan derivatives, such as furan dicarboxylic acid (FDCA), from a starting compound or substrate having a carbonyl functional group (C?O), with hydroxy-substituted carbon atoms at alpha (?) and beta (?) positions, relative to the carbonyl functional group. According a particular embodiment, an ?-, ?-dihydroxy carboxylate is dehydrated to form a dicarbonyl intermediate by transformation of the ?-hydroxy group to a second carbonyl group and removal of the ?-hydroxy group. The dicarbonyl intermediate undergoes cyclization and dehydration, to produce the 2-substituted furan derivative. Optionally, a further step of oxidation may be carried out, for example to convert a hydroxymethyl group, as a 5-substituted about the furan ring, to a carboxy group of FDCA.
