Title: Dieter Becher: Innovator in Chemical Engineering
Introduction
Dieter Becher is a notable inventor based in Dormagen, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of aromatic compounds. With a total of 4 patents to his name, Becher's work has had a considerable impact on industrial processes.
Latest Patents
One of Becher's latest patents involves the production of aromatic diamino compounds using a modified Raney catalyst. This innovative process allows for the hydrogenation of corresponding dinitro compounds in the presence of a specially treated alloy catalyst. The catalyst is composed of 50-95 wt % aluminum, 4-45 wt % nickel and/or cobalt, and 1-46 wt % of at least one modifying metal. The hydrogenation process is optimized to occur at temperatures ranging from 170°C to 250°C and pressures between 15-50 bar. Additionally, the heat generated during hydrogenation is utilized to produce steam, enhancing the efficiency of the process.
Another significant patent by Becher outlines a method for working up aqueous amine solutions. This process separates amines from aqueous solutions containing volatile organic compounds through distillation in a column. The generated vapors are condensed and passed into a separating device to remove volatile organic compounds. The remaining liquid is then returned to the distillation column, while water is removed in a sidestream, leaving diamine as the residue. This method is particularly effective for recovering aromatic diamines from solutions that accumulate during the hydrogenation of dinitro aromatic compounds.
