  • Patent number: 11207661
    Abstract: A process for preparing a peptized alumina having increased solids and acid contents and a decreased water content. The process comprising mixing a boehmite or pseudoboehmite alumina and acid with a high intensity, high energy mixer at a ratio of 0.16 to 0.65 moles acid/moles alumina for a time period sufficient to form a substantially free-flowing solid particulate having a solids content of 45 to 65 wt %. When used in catalyst manufacture, peptized alumina produced by the process provides an increased rate in catalyst production and decreased costs due to high solids concentration and the presence of less water to be evaporated.

  • Publication number: 20210365058
    Abstract: An analog front end circuit with pulse width modulation current compensation comprises sensing a current condition and determining if the current condition is a positive or negative current condition. An appropriate control signal is determined according to the current condition and sent to turn on a positive current electronic switch if the current condition is a negative current condition or sent to turn on a negative current electronic switch if the current condition is a positive current condition. A positive compensation current flows to offset negative parasitic current when the positive current electronic switch is turned on and a negative compensation current flows to offset positive parasitic current when the negative current electronic switch is turned on. A master control unit utilizes pulse width modulation signals of various widths associated with various current conditions to be sent to turn on the positive electronic switch or the negative electronic switch.
