Title: Maria Johanna Wilhelmina Van Wieringen: Innovator in Catalysis Technology
Introduction
Maria Johanna Wilhelmina Van Wieringen is a notable inventor based in Amsterdam, Netherlands. He has made significant contributions to the field of catalysis through his innovative patents. With a total of 2 patents, Van Wieringen has focused on enhancing processes that are crucial for chemical reactions.
Latest Patents
His latest patents include advancements in particle extrusion and the Fischer Tropsch process. The first patent, titled "Particle extrusion," describes a die designed for extruding elongate particles suitable for use in catalysis. This die features multiple channels that extend from an inlet to an outlet, with each channel comprising a first section that has a helical bore with a non-circular cross-section, and a second section with a cylindrical bore. The cylindrical bore has a diameter that is equal to or greater than that of the first section, and the second section is at least twice as long as the diameter of the first section.
The second patent, "Fischer Tropsch process using improved extrudates," outlines a process for conducting a Fischer Tropsch reaction. This process involves providing syngas to a reactor that contains catalyst particles produced by extruding a paste using a die similar to the one described in his first patent. The process specifies conditions such as a temperature range from 125 to 350°C, a pressure from 5 to 150 bar absolute, and a gaseous hourly space velocity from 500 to 10,000 Nl/l/h. The final step involves removing Fischer Tropsch products from the reactor.
