Title: Petra Look-Herber: Innovator in Chemical Processes
Introduction
Petra Look-Herber is a distinguished inventor based in Braunschweig, Germany. She has made significant contributions to the field of chemical engineering, particularly in the production of innovative materials and coatings. With a total of 2 patents to her name, her work has garnered attention for its practical applications and advancements in technology.
Latest Patents
One of her latest patents is a method for producing granulated sodium percarbonate. This innovative process utilizes fluidized bed granulation, where an aqueous sodium carbonate solution and a hydrogen peroxide solution are sprayed onto nuclei in a fluidized bed, followed by the evaporation of water. Notably, this method eliminates the need for phosphorus-containing crystallization inhibitors, which can cause clogging and incrustations in the nozzle. Instead, the solutions are mixed externally through separate channels in a single ternary atomizer nozzle.
Another significant patent involves the production of catalytically active coatings for aluminum oxide shaped articles used in hydrogen cyanide production via the BMA method. This method employs a suspension containing platinum metal and finely divided aluminum in a carrier liquid for coating. The process allows for varying coating thicknesses in a single stage and reduces health risks by eliminating the previously necessary hydrogenation stage after each impregnation.
