Title: Dirk Crauwels: Innovator in Platinum Group Metal Recovery
Introduction
Dirk Crauwels is a notable inventor based in Boechout, Belgium. He has made significant contributions to the field of metallurgy, particularly in the recovery of platinum group metals (PGM). With two patents to his name, Crauwels has developed innovative processes that enhance the efficiency of metal recovery from various catalysts.
Latest Patents
Crauwels' latest patents include a method for the recovery of platinum group metals from catalysts comprising silicon carbide. This invention outlines a process that involves preparing a metallurgical charge by mixing PGM-bearing catalysts with an Fe-oxide compound. The process is designed to oxidize at least 65% of the silicon carbide, allowing for the formation of a liquid Fe-based bullion that contains PGM, along with a liquid slag. The results demonstrate good to excellent yields of PGM.
Another significant patent focuses on the recovery of PGM from spent homogeneous catalysts present in an organic phase. This disclosure presents a pyrometallurgical process that concentrates PGM, particularly rhodium, in a metallurgical phase. The process involves using a molten bath furnace equipped with a submerged injector for liquid fuel firing. By feeding the spent homogeneous catalyst and an oxygen-bearing gas through the injector, a major portion of the PGM is recovered in the metallic phase, while the environmentally harmful organic waste is effectively destroyed.
