Title: Heinrich Bunger: Innovator in Heavy Metal Catalyst Recovery
Introduction
Heinrich Bunger is a notable inventor based in Siegburg, Germany. He has made significant contributions to the field of chemical engineering, particularly in the recovery and reuse of heavy metal oxidation catalysts. With a total of 4 patents to his name, Bunger's work has implications for both environmental sustainability and industrial efficiency.
Latest Patents
Bunger's latest patents include a process for the recovery and reuse of heavy metal oxidation catalysts. This innovative method involves extracting catalysts from residues in the Witten DMT process by mixing and settling the residue with water or dilute aqueous solutions of low-molecular, aliphatic monocarboxylic acids at temperatures ranging from 70 to 160 degrees Celsius. The process also emphasizes the recycling of the extract of high-boiling distillation residues back into the DMT process, maintaining a quantitative ratio of 1:0.9 to 1:0.1, preferably 1:0.5 to 1:0.3.
Another significant patent focuses on the method for obtaining and reusing oxidation catalysts in the Witten DMT process. This involves extracting heavy metal oxidation catalysts from high-boiling distillation residues and recycling the extract into the oxidation stage of the Witten process. The process controls the quantitative ratio of trimellitic acid and its monomethyl ester to the heavy metal catalyst to ensure optimal recovery.
