Title: Werner Sebb: Innovator in Bleaching Technologies
Introduction
Werner Sebb is a notable inventor based in Geretsried, Germany. He has made significant contributions to the field of bleaching technologies, particularly in the processing of cellulosic pulp and natural chalk. With a total of 2 patents, his work has had a considerable impact on industrial applications.
Latest Patents
Sebb's latest patents include innovative methods for bleaching and delignifying cellulosic pulp using a caroate/caro's acid solution. Additionally, he has developed a process for bleaching natural chalk. This process involves preparing an aqueous suspension consisting of 50 to 80% by weight fine-grained natural chalk and 50 to 20% by weight water. The suspension contains 0.1 to 1.5% by weight of a dispersant based on the dry weight of the chalk. It may also include a hydrogen peroxide stabilizer or activator. The suspension is then wet ground to reduce the particle size until about 90% of the particles have a grain size of less than 4 micrometers. Following this, the suspension is mixed with hydrogen peroxide or a salt of hydrogen peroxide with a divalent metal at temperatures between 50°C and 99°C, and at a specific pH-value or an alkaline pH. The mixture is stirred intensively until it is well mixed and foaming begins. The suspension is allowed to stand until foam formation is complete, after which the foam containing dark particles is separated.
