Title: Innovations by Inventor Dietmar Hein
Introduction
Dietmar Hein is a notable inventor based in Nuremberg, Germany. He holds four patents that showcase his contributions to environmental technologies, specifically in the area of catalyst development for reducing nitrogen oxides in flue gases. His innovative approach aims to enhance the efficiency and effectiveness of pollution control methods.
Latest Patents
Dietmar Hein's most recent patents focus on a catalyst designed to reduce nitrogen oxides in flue gases through a specific composition and a reducing agent. This catalyst boasts increased resistance to common catalyst poisons, such as arsenic trioxide.
The composition primarily includes 60-90% by weight of titanium, 10-30% by weight of molybdenum, and 0.2-10% by weight of vanadium, all presented as their respective oxides. A significant aspect of this invention is the use of a very pure titanium dioxide which contains less than 500 ppm of calcium and less than 100 ppm of iron. The titanium dioxide is predominantly in the anastase modification and features a mean particle size of 10 to 100 nm, a mean pore radius of 10 to 30 nm, and a BET surface area of 10 to 80 m² per gram.
The manufacturing process involves wet-grinding a suspension of the titanium dioxide with vanadium pentoxide and molybdenum trioxide in specified proportions. Post-grinding, the suspension is dried and precalcined at temperatures ranging from 450°C to 550°C, followed by comminution into particles smaller than 180 μm. The resulting pulverized material is mixed with water, coated onto a metal substrate, dried, and calcined for several hours to yield the final catalyst product.
