Title: Ernst Wallis: Innovator in Metal Reprocessing Technologies
Introduction
Ernst Wallis is a notable inventor based in Eschborn, Germany, recognized for his contributions to the field of metal reprocessing. With a total of 5 patents, Wallis has developed innovative methods that enhance the recycling of metal-containing materials, particularly in the context of industrial waste.
Latest Patents
One of Wallis's latest patents is a method of reprocessing zinc- and iron oxide-containing residual material. This invention outlines a process where zinc- and iron oxide-containing dust and/or sludge is granulated with water. The granules, along with carbonaceous material, are introduced into a circulating fluidized bed system. The gas-solids suspension is then fed into a second fluidized bed reactor, where the solids are recycled back to the first reactor. The process efficiently utilizes oxygen to gasify the carbonaceous material, resulting in the discharge of iron oxide-containing material and zinc-containing material with the exhaust gas.
Another significant patent involves the process of regenerating waste pickle, which contains metal salts and acids. This waste, generated during the surface treatment of rolled steel, undergoes acid dialysis followed by membrane electrolysis. This innovative approach allows for the recycling of free acids and the recovery of metals in a form suitable for direct use in melting processes.
Career Highlights
Throughout his career, Wallis has worked with prominent companies such as Metallgesellschaft Aktiengesellschaft and VDM Nickel-Technologie Aktiengesellschaft. His experience in these organizations has contributed to his expertise in metal processing technologies and waste management.
Collaborations
Wallis has collaborated with notable professionals in his field, including Ulrich Heubner and Michael Kohler. These partnerships have likely facilitated the development and refinement of his innovative processes.
Conclusion
Ernst Wallis stands out as a significant figure in the realm of metal reprocessing, with a focus on sustainable practices and innovative technologies. His patents reflect a commitment to improving industrial processes and enhancing the recycling of valuable materials.
