Jürgen Glenneberg

Title: Jürgen Glenneberg: Innovator in Hydrogen Peroxide Technologies

Introduction: Jürgen Glenneberg is a notable inventor hailing from Offenbach, Germany. With a strong background in the chemical industry, he holds a total of four patented innovations focused on the concentration and preparation of hydrogen peroxide.

Latest Patents: Glenneberg's latest innovations include a groundbreaking process for the concentration of aqueous hydrogen peroxide by crystallization. This process involves arranging a cooling surface within a crystallizing vessel, which is first wetted with hydrogen peroxide and then subjected to a rapid cooling rate. The cooling rate, maintained at a minimum of 1 K/s but preferably between 10 and 30 K/s, allows for the formation of seed crystals. As the vessel fills with hydrogen peroxide starting material, crystallization occurs from these seed crystals, leading to the development of a crystal layer. Following the discharge of the lower concentration mother liquor, a sweating operation with a gradual temperature increase enhances the hydrogen peroxide concentration within the crystal layer.

In addition, Glenneberg has patented a process for preparing hydrogen peroxide. This involves the hydrogenation stage of the anthraquinone process carried out in a hydrogenation reactor utilizing a fixed bed of particulate catalyst. A key aspect of this method is that the working solution, which includes the reaction carrier and a gas phase containing hydrogen, is passed upwards through the reactor. The empty tube speed of the working solution ranges from 0.05 to 100 m/h, with optimal rates between 10 and 50 m/h, which significantly extends the catalyst's service life.

Career Highlights: Throughout his career, Jürgen Glenneberg has made significant contributions to the field of chemical engineering, particularly in hydrogen peroxide production. He has been associated with notable companies like Degussa AG and Degussa - Huls AG, where he applied his expertise to advance industry standards and practices.

Collaborations: Glenneberg has had the opportunity to work alongside talented colleagues, including Rudolf M. Wagner and Matthias Creutz. These collaborations have contributed to the development and refinement of his patented processes, showcasing the importance of teamwork in innovation.

Conclusion: Jürgen Glenneberg's contributions to the field of hydrogen peroxide technology through his innovative patents highlight his impact on chemical engineering. His work not only represents personal achievement but also advances industrial processes crucial for the production and concentration of hydrogen peroxide.
