Title: The Innovations of Henry F. Barry

Introduction

Henry F. Barry is an accomplished inventor based in Ann Arbor, MI (US). He holds a total of 3 patents that showcase his contributions to the field of chemical engineering and materials science. His work primarily focuses on the recovery and recycling of valuable materials, particularly molybdenum, from industrial processes.

Latest Patents

One of Barry's latest patents is titled "Recovery and recycle of molybdenum values from coal liquefaction residue." This innovative process involves treating the residue from a molybdenum-catalyzed coal liquefaction process to recover molybdenum in a form that can be easily recycled and reused as a catalyst. The method includes mixing the residue with an excess of alkali, subjecting it to an oxidative roast, and then leaching the roasted product to extract molybdenum values. The final steps involve acidifying and ammoniating the solution to form a molybdenum-bearing precipitate, which can be dissolved in aqueous ammonium hydroxide for application in coal liquefaction.

Another significant patent by Barry is the "Molybdate corrosion inhibiting pigment and method for preparing same." This patent describes a method for creating a corrosion-inhibiting pigment used in protective coatings for ferrous substrates. The process involves slurrying a particulated inert carrier in an aqueous solution with molybdic oxide and adding metal oxides to deposit the corresponding metal molybdate on the carrier particles. The coated carrier is then separated, dried, and calcined at an elevated temperature to produce the final product.
