Latest Patents

Ack holds a patent for the CTMP-process, which boasts a wood yield above 88%. The pulp produced has a low resin content of less than 0.15%, a long fiber content exceeding 70%, a short fiber content below 10%, and a shive content under 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 of at most 2 minutes, often less than 1 minute. The process utilizes a warm impregnating liquid at temperatures of at least 100°C, ideally around 130°C, and preheats the chips at temperatures between 150°C and 175°C.
