Title: Innovations of Hans Höglund in Chemithermomechanical Pulp Production
Introduction
Hans Höglund is a notable inventor based in Matfors, Sweden. He has made significant contributions to the field of pulp production, particularly through his innovative CTMP-process. This process is designed to produce absorbent, chemithermomechanical pulp from lignocellulosic material, achieving impressive yields and quality.
Latest Patents
Höglund holds a patent for the CTMP-process, which boasts a wood yield exceeding 88%. The pulp produced has a low resin content of less than 0.15%, a long fiber content above 70%, a short fiber content below 10%, and a shive content below 3%. The method involves several steps, including impregnating, preheating, defibering, and washing the material. Notably, the impregnation and preheating occur in a single vessel within a combined time frame of no more than 2 minutes, often as short as 0.5 minutes. The process utilizes a warm impregnating liquid at temperatures of at least 100°C, ideally around 160-170°C for preheating.
