Patents by Inventor Otto Krumberger

Otto Krumberger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for the treatment of a methanol reforming catalyst
    Patent number: 6280701
    Abstract: A method for the treatment of a methanol reforming catalyst includes pre-aging the catalyst by baking it out in a dry atmosphere in order thereby to complete its inherent initial loss of volume before the start of the methanol reforming reaction. The method may be used for methanol reforming reactors in fuel-cell-operated motor vehicles.
    Type: Grant
    Filed: May 11, 2000
    Date of Patent: August 28, 2001
    Assignees: Xcellsis GmbH, BASF Aktiengesellschaft

  • Process for operating a methanol reforming apparatus
    Patent number: 6074770
    Abstract: A method for the operation of a methanol reforming apparatus wherein, during the operation of the reforming reaction, methanol is reformed in a methanol reforming reactor using a methanol reforming catalyst. The reforming reaction is interrupted at given times for catalyst reactivation phases, during which the reactor containing the methanol reforming catalyst is flushed with hydrogen gas for the activity-regenerating treatment of the methanol reforming catalyst which loses its catalytic activity. The process may be used for the operation of methanol reforming apparatus in fuel-cell-operated motor vehicles for the production of hydrogen from liquid methanol.
