Title: Innovative Contributions of Horst Kruger in Cellulose Processing
Introduction
Horst Kruger, an accomplished inventor based in Darmstadt, Germany, has made significant strides in the field of cellulose processing. With a total of six patents to his name, Kruger is known for his pioneering techniques in delignification and bleaching processes that enhance the production of cellulose.
Latest Patents
Among his recent innovations, two patents stand out prominently. The first is a process for the delignification and acid bleaching of cellulose which utilizes both oxygen and hydrogen peroxide. This process involves the use of magnesium oxide (MgO) during delignification with oxygen, followed by simultaneous bleaching of cellulose at a pH of less than five.
The second noteworthy patent focuses on the bleaching of cellulose using organic peracids. This method entails bleaching cellulose in the acidic region with an organic peracid, which is derived from a corresponding carboxylic acid reacted with hydrogen peroxide in the presence of a mineral acid. Following this, an alkaline peroxide bleaching step is performed without requiring an intermediate washing of the cellulose, thereby streamlining the process.
