Title: Werner Stender: Innovator in Catalyst Manufacturing

Introduction

Werner Stender is a notable inventor based in Raesfeld, Germany. He has made significant contributions to the field of catalyst manufacturing, holding a total of three patents. His work primarily focuses on processes that enhance the efficiency of catalysts used in various chemical reactions.

Latest Patents

Stender's latest patents include a process for the manufacture of a catalyst for the reduction of nitrogen oxides in exhaust gases. This invention involves a catalyst that contains a metal oxide and is particularly effective for catalytic reduction with ammonia. The process begins with screening natural goethite iron ore to the required grain size, followed by treatment with sulfuric acid. The goethite iron ore is then heated to a temperature that approximates the conditions under which it will be used in the catalytic reaction.

Another significant patent by Stender is for the manufacture of catalyst moldings. In this process, a natural raw material containing components such as Fe₂O₃ or Cr₂O₃ is screened to a grain size of approximately 0.25 mm or less. This base mixture is thoroughly blended, and concentrated sulfuric acid is added. The resulting mixture is then pressed into a molding using a hydraulic press at a pressure of around 500 bar.

Career Highlights

Throughout his career, Stender has worked with various companies, including Didier Engineering GmbH and Didier-Werke AG. His experience in these organizations has contributed to his expertise in catalyst technology and innovation.
