Title: Manfred Stoltenberg: Innovator in Ketene Production
Introduction
Manfred Stoltenberg is a notable inventor based in Frankfurt, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of ketene. His innovative approach has led to the development of a patented process that enhances the efficiency of ketene preparation.
Latest Patents
Stoltenberg holds a patent for a process for the preparation of ketene. This process involves the thermal, catalytic cracking of acetic acid under reduced pressure. The hot cracked gases are cooled to approximately 0 to -10 degrees Celsius, during which water, unreacted acetic acid, and acetic anhydride are condensed. The quantity of acetic acid used for the thermal cracking reaction is specified to be between 0.5 to 2.5 tons per hour per cubic meter, relative to the volume of a shell-and-tube heat exchanger through which the cracked gas is passed. The pressure drop in the tubular heat exchanger is maintained between 50 to 150 mbars, with a surface/volume ratio of 60 to 120 meters.
