  • Publication number: 20230249119
    Abstract: A hydrogen feed stream comprising oxygen and one or more impurities selected from the group consisting of nitrogen, argon, methane, carbon monoxide, carbon dioxide, and water, is purified by first removing oxygen using a copper oxide and/or manganese oxide getter, then using a cryogenic temperature swing adsorption (CTSA) process with high overall recovery of hydrogen. The oxygen getter prevents an explosive mixture of hydrogen and oxygen from occurring in the CTSA during regeneration.

  • Patent number: 7015176
    Abstract: A process is described for the synthesis of an aryl sulfur pentafluoride compound. In one embodiment of the present invention, there is provided a process for preparing an aryl sulfurpentafluoride compound comprising: combining an at least one aryl sulfur compound with a fluorinating agent to at least partially react and form an intermediate aryl sulfurtrifluoride product; and exposing the intermediate aryl sulfurtrifluoride product to the fluorinating agent and optionally a fluoride source to at least partially react and form the aryl sulfurpentafluoride compound.
