Title: Harro Lentz: Innovator in Cellulose Treatment
Introduction
Harro Lentz is a notable inventor based in Siegen, Germany. He has made significant contributions to the field of cellulose treatment, particularly through his innovative processes that enhance the activation of cellulose for chemical reactions.
Latest Patents
Lentz holds a patent for a process for the treatment of cellulose. This process involves bringing cellulose into contact with liquid ammonia at pressures higher than atmospheric pressure within a pressure vessel. The subsequent rapid reduction of pressure to atmospheric pressure allows for the activation of cellulose pulp, which contains at least 92 mass % alpha-cellulose. The ammonia acts on the pulp at room temperature or higher, and after expansion, the residual ammonia is removed while maintaining the state of activation. This method is particularly suitable for large-scale industrial applications, especially for pulp that is to be acetylated, achieving a homogeneous and high-grade activation without the need for costly cooling apparatus.
