Title: Gunter Jacobsen: Innovator in Ketene Technology
Introduction
Gunter Jacobsen is a notable inventor based in Frankfurt, Germany. He has made significant contributions to the field of chemical engineering, particularly in the preparation and compression of ketene. With a total of 3 patents to his name, Jacobsen's work has had a lasting impact on industrial processes.
Latest Patents
Jacobsen's latest patents include a process for the preparation of ketene and a process for compressing ketene. The preparation process involves the thermal, catalytic cracking of acetic acid under reduced pressure. In this innovative method, the hot cracked gases are cooled to approximately 0 to -10 degrees Celsius, resulting in the condensation of water, unreacted acetic acid, and acetic anhydride. The quantity of acetic acid used for the thermal cracking reaction is carefully controlled, ranging from 0.5 to 2.5 tons per hour per cubic meter, relative to the volume of a shell-and-tube heat exchanger. Additionally, the pressure drop in the tubular heat exchanger is maintained between 50 to 150 mbars, with a surface/volume ratio of 60 to 120 m^-1. His second patent focuses on compressing ketene using a liquid ring pump that employs ketene-containing diketene as the operating liquid.
