Latest Patents
Wenche holds a patent for a process titled "Process for acid bleaching of lignocellulose-containing pulp with a magnesium compound." This invention outlines a method for delignification and bleaching of chemically digested lignocellulose-containing pulp. In the first embodiment, the pulp is acid treated at a pH of between about 1 and about 6. Following this, a water-soluble compound containing an alkaline earth metal is added at a pH of between about 1 and about 7 before the pulp is treated with a chlorine-free bleaching agent.
