Title: The Innovations of Donald C. Cronauer
Introduction
Donald C. Cronauer is a notable inventor based in Gibsonia, PA (US). He has made significant contributions to the field of chemical engineering, particularly in catalyst production and oil upgrading. With a total of 9 patents to his name, Cronauer's work has had a lasting impact on industrial processes.
Latest Patents
One of Cronauer's latest patents is a process for producing a catalyst by depositing molybdenum. This invention relates to a method for selectively removing molybdenum values from a spent catalyst and producing a fresh molybdenum-containing catalyst. The method involves contacting anhydrous gaseous hydrogen chloride at an elevated temperature with the metal-containing catalyst, which is substantially free of carbonaceous material. This process allows for the selective removal of molybdenum while preserving other metals such as iron, titanium, cobalt, and nickel, along with the supporting alumina or silica. Another significant patent involves the denitrogenation of shale oil. This process upgrades crude shale oil containing nitrogen by contacting it in a hydrogenation zone with hydrogen in the presence of a hydrogenation catalyst. This effectively removes a selected portion of the nitrogen, resulting in a shale oil of substantially lower nitrogen content.
